2019 - Profiling of filamentous bacteria in activated sludge by 16s RNA ampli...
Abstract: In this study, filamentous bacteria in the activated sludge of a WWTP were investigated throughout a one-year period using high-throughput short-read (Illumina) and full-length (PacBio) 16S rRNA gene amplicon sequencing. The results showed that a total of 28 filamentous bacteria genera
were identified using Illumina sequencing. Also, we found 25 species using PacBio sequencing, belonging to Curvibacter, Mycobacterium, Haliscomenobacter, Defluvicoccus, Sphaerotilus, Thiothrix, Leptothrix, Gordonia and Tetrasphaera genera. Active Volatile Suspended Solids (AVSS) were
calculated from ATP data contained in living microorganisms, this parameter represents the living biomass concentration, and the food/microorganisms ratio (F/M ratio) was calculated using AVSS instead of MLVSS. To assess the contribution of the F/M ratio to the variability observed in the filamentous bacteria structure we carried out distance-based linear models (DISTLM) and distancebased redundancy analysis (dbRDA).

Researchers at the University of North Carolina Wilmington collaborated with IKA Works, Inc. to create a 10 liter closed, stirred-tank photobioreactor to produce high densities of dinoflagellate microalgae. Using cultures of Amphidinium gibbosum and Alexandrium ostenfeldii/peruvianum, the photobioreactor generated equal biomass to eighty liters of static culture and cell counts of A. gibbosum reached up to 300 million cells per liter. The photobioreactor provides an effective system for growing dinoflagellates at scale while using fewer resources than traditional methods.

Presentation- UVA researcg Cyanobactbloom
This document summarizes a study that aimed to:
1) Elucidate the behavior of cyanobacteria under nitrate-nitrogen stress
2) Determine if the cyanobacterial cell wall specifically responds to nitrate stress
3) Develop tools to monitor cyanobacterial blooms
The study found that nitrate depletion caused bleaching of cyanobacterial cells and slower growth. Analysis of cell wall proteins showed new proteins were synthesized under nitrate stress. The cell wall responded specifically to different nitrogen sources. The study concluded the cyanobacterial strain demonstrated a specific adaptation of the cell wall to nutrient stress.
Role of fungi in biomethanation process
Anaerobic fungi particularly belonging to the phylum Neocallimastigomycota, are the most basal lineage of the kingdom Fungi. These fungi are principally known from the digestive tracts of the larger mammalian herbivores, where they play an inevitable role as primary colonisers of ingested forage. Recent researches indicate their appearance in herbivorous reptiles like the green iguana and termites also.

Inhibhition of quorum sensing
This seminar discusses quorum sensing in bacteria and the potential to develop natural quorum sensing inhibitors from marine algae as anti-fouling agents. Quorum sensing allows bacteria to communicate and coordinate behaviors at high cell densities through signaling molecules. The speaker aims to screen marine algae for compounds that can inhibit quorum sensing and thereby prevent biofilm formation and fouling of marine structures. Inhibiting quorum sensing could provide a non-toxic alternative to toxic anti-fouling paints currently used.
NESS 48poster_HF_VF_LN_Final (1)
This study examined the impacts of gold nanoparticle charge and ligand type on surface binding and toxicity to the gram-positive bacterium Bacillus subtilis. Positively charged PAH-AuNPs showed the highest cell surface binding and toxicity, while negatively charged MPA-AuNPs had minimal effects. Differences in cell wall structures between B. subtilis and the gram-negative bacterium Shewanella oneidensis resulted in different surface binding of nanoparticles. The findings illustrate the importance of electrostatic interactions and cell surface structures in nanoparticle-biological interactions.
Bioluminescence assay
This document discusses the analytical technique of bioluminescence. It begins by defining bioluminescence as the production and emission of light by living organisms through a chemical reaction involving luciferin and luciferase. This reaction produces light energy. Bioluminescence assays can be used to measure cell proliferation, apoptosis, drug metabolism, and kinase activity. The document then explains the principle behind bioluminescence and provides steps for a bioluminescence procedure using cell lysis and a luminometer to measure light emission. Finally, some applications of bioluminescence are mentioned such as food testing, imaging, and medical research.
displayarticle
This document describes an experiment assessing the use of green crabs (Carcinus maenas) as indicator species in the Multispecies Freshwater Biomonitor (MFB), an online water quality biomonitor. The experiment tested whether: 1) the electrical field of the MFB affects crab behavior; 2) ammonia presence alters crab behavior; 3) the electrical field further impacts behavior in ammonia's presence. Results showed the electrical field did not significantly impact crabs on its own. Ammonia did alter crab behavior in a dose-dependent manner. Five distinct crab behaviors were detected by the MFB. Overall, green crabs appear suitable for use in the MFB as marine biomonitors.
Marine Bio-Prospecting
This document discusses the importance of marine biotechnology and summarizes some key points. Marine organisms contribute to the oxygen cycle and help regulate the Earth's climate. They represent an untapped reservoir of biologically active compounds that can potentially lead to new medicines, cosmetics, nutraceuticals, enzymes, fuels, foods and more. Microbes, fungi, invertebrates and other marine sources have been found to produce secondary metabolites and bioactive compounds with applications such as antibiotics, anticancer agents, anti-inflammatories and more. However, marine bioprospecting faces challenges such as difficulties in synthesis and cultivation of marine microorganisms.
Metagenomics
This document discusses metagenomics, which is the study of microbial communities directly in their natural environments without isolating individual species. It outlines some key aspects of metagenomics including that most prokaryotes cannot be cultured, the use of metagenomics to study viral communities, and approaches such as functional screening and sequence-based screening. Limitations and future directions are also mentioned. Metagenomics provides insights into microbial interactions, metabolism, and genomics that were previously unknown.
Glowing plants
1. The document discusses developing glowing plants through inserting luciferase genes from bioluminescent bacteria into plants. This could create natural street lighting and reduce CO2 emissions.
2. Luciferase produces a chemical reaction that causes bioluminescence in fireflies. Researchers aim to transfer the bacterial luciferase-luciferin system, including the lux operon genes, into plants like tobacco through Agrobacterium-mediated transformation.
3. Experiments have shown that luciferase expression can vary in transgenic tobacco plants depending on DNA insertion location, with expression in some veins but not others. This demonstrates challenges in stable, uniform luciferase expression across plant tissues.

Impact of heavy metals pollution on molecular genetics of some medicinal plants
This document summarizes a study on the impact of heavy metal pollution on the molecular genetics of three medicinal plant species. DNA was extracted from plants collected from polluted and non-polluted sites. Inter simple sequence repeats (ISSR) and amplified fragment length polymorphisms (AFLP) markers were used to analyze genetic differences at the molecular level. ISSR analysis generated 172 bands from 5 primers, showing differences between polluted and non-polluted plants. AFLP analysis using 2 primer pairs produced 116 bands, with 79 being polymorphic. Dendograms based on ISSR and AFLP data showed genetic differences between polluted and non-polluted plant populations, indicating heavy metal pollution affects plant genetics at the molecular level

Microorganisms involved in the biodegradation of municipal solid waste (MSW) in Abakaliki dumps were isolated and characterized using standard microbiology technique. Five municipal solid waste dumpsites located within Abakaliki metropolis, Ebonyi State, Nigeria were used for this study. The potential of individual microbial isolate to grow on the MSW was also studied using nutrient broth supplemented with mineral salt media and thereafter five of the best microbial degraders were subjected to a 98 days biodegradation studies using weight loss, change in pH, density change and CO2 evolution as indices of success. The study showed that different dumpsites had different temperature readings, bacterial and fungal load, caused by the volume of waste dumped and the habits of the inhabitants. The bacteria population isolated from the dumpsites included Pseudomonas spp, Bacillus spp, Lactobacillus spp, Streptococcus spp, Staphylococcus spp and Micrococcus spp. Penicillum spp, Mucor spp, Aspergillus spp, Fusarum spp, Saccharomyces spp and Candida spp were the fungal species isolated from the dumpsites. The bacteria with the highest growth rate were Bacillus spp, Pseudomonas spp, while Aspergillus spp, Mucor spp, and Saccharomyces spp recorded the highest growth rate for the fungi isolates. The fungi group proved to be better microbial degraders than the bacteria population as a percent weight loss of 1.11 ± 0.03, 1.04 ± 0.05 and 1.23 ± 0.02 were achieved by Saccharomyces spp, Mucor spp and Aspergillus spp respectively. This was in comparison to the bacteria group, which recorded 0.89 ± 0.04 and 0.87 ± 0.03 percent weight loss by Pseudomonas spp and Bacillus spp. Increases in CO2 evolution was equally recorded by both the fungal and bacterial groups as well as increase in acidity. There was a positive correlation among CO2 evolution, weight loss and density for all the test organisms. However, there was no relationship between pH and CO2 evolution, weight loss and density.
Improving microalgae for biotechnology - from genetics to synthetic biology
The document discusses genetic engineering approaches for microalgae. It describes forward genetics methods like chemical and physical mutagenesis that generate random mutants for screening. It also describes reverse genetics methods like insertional mutagenesis that allow targeted modification of specific genes. The goal is to generate strains with desired traits like increased lipid or starch production for industrial applications.
Developement of Nematicide Resistance in Nematodes
This document summarizes the development of resistance in nematodes to nematicides and anthelmintics. It discusses key concepts like the definition of resistance, types of resistance, and mechanisms of resistance development. It also presents a case study on the development of resistance in nematode populations exposed to long-term treatment with carbofuran nematicide in vineyard plots. The study found increasing tolerance in the nematode populations to carbofuran through field and laboratory tests, demonstrating the development of resistance under field conditions. Factors influencing the spread of resistance and integrated control approaches are suggested to reduce dependency on chemicals and slow the development of resistance.

The document describes the isolation and molecular characterization of Rhizobium bacteria from soil samples. Key steps included:
1. Isolating Rhizobium colonies from soil dilutions on nutrient agar plates.
2. Amplifying genes from the bacterial DNA using PCR with specific primers.
3. Analyzing the amplified genes using various bioinformatics tools like NCBI BLAST, codon usage analysis, and phylogenetic analysis to identify and characterize the bacteria.
Bacteria identification Biosensor
This document describes a new method for rapidly identifying bacteria using gold nanoparticles conjugated to fluorescent polymers. It finds that:
1) When these nanoparticle-polymer constructs interact with different bacteria, they produce unique fluorescence response patterns that can differentiate between bacterial species and strains within 30 minutes.
2) Linear discriminant analysis of the response patterns from three constructs allowed accurate identification of 12 bacterial species and differentiation of strains within a single species.
3) The method relies on bacteria displacing the fluorescent polymers from the gold nanoparticle surface, restoring fluorescence. Interactions between hydrophobic regions on bacteria and the nanoparticles enhance this effect.
Hariom chemotaxis iiiiiii
Chemotaxis is the movement of an organism in response to chemicals in its environment. There are two types: positive chemotaxis where an organism moves toward an attractant, and negative chemotaxis where it moves away from a repellent. Bacteria like E. coli use runs and tumbles to navigate chemical gradients - detecting increases in attractants which reduces tumbling, and increases in repellents which increases tumbling. Chemotaxis allows bacteria in soil to move toward nutrient-rich root exudates from plants, potentially forming symbiotic relationships. Factors like chemical compounds, temperature, pH, and water potential can influence bacterial chemotaxis.
Taxonomy, phylogeny, epidemiology rupinder
Environmental microbiology pertains to microorganisms found in air, water, soil, and wastewater that can affect public health or decompose organic matter. The document discusses taxonomy, which is the classification of organisms, and epidemiology, which is the study of disease patterns in populations. It also examines airborne pathogens and their lifecycles, noting that microbes are often suspended in air droplets and face stresses like desiccation and temperature changes as they are launched, transported, and deposited in the atmosphere.
History, Introduction & Scope Of Microbiology
This document discusses the history and scope of microbiology. It covers key discoveries such as the first observation of microorganisms by Antonie van Leeuwenhoek and the conflict over spontaneous generation that was resolved by experiments showing that microbes were required for decay and fermentation. The "golden age of microbiology" established germ theory and Koch's postulates. This led to the development of medical, agricultural, industrial, and food microbiology.

Microbial community analysis in anaerobic palm oil mill effluent (pome) waste...
Microorganisms play a key role in wastewater bio-treatment processes and understanding the microbial community structure is of great importance to improve treatment performance. Denaturing gradient gel electrophoresis (DGGE) was used to monitor succession of the microbial community and thus predominant bands were sequenced to reveal the microbial community composition inside palm oil mill effluent (POME) wastewater.DNA bands from DGGE gels were excised with a sterile blade and placed in 1.5 ml eppendorf tube containing 50 μl deionized water (ddH2O). Tubes were incubated overnight at 4C to elute the DNA. Eluted DNA was purified using QIAquick gel extraction kits (QIAGEN, Inc., Valencia, CA) and was frozen and thawed three times.Microbial DNA successfully excised and purified from DGGE was amplified using polymerase chain reaction (PCR).Five micro liters of the supernatant were used as a template to re-amplify the DNA using 16s rDNA primers,341f (with no GC-clamp) (5'- cct-acg-gga-ggc-agc-ag-3') and reverse(r) primers 907r (5'-ccc-cgt-caa-ttc-att-tga-gtt-t-3'). Amplification was repeated referring to the steps in ‘PCR amplification of 16s rDNA’. PCR products from agarose gels were cut and purified using QIAquick Gel Extraction Kit (QIAGEN, Inc., Valencia, CA), which were similar to the purification steps after recovery of DNA from DGGE, and sequenced in both directions with the same primers (with no GC-clamp) as used in PCR. Moreover, start-up is an important step in establishing proper community structure in all kinds of biological treatment processes. In anaerobic POME wastewater, 6 sequences of Firmicutes, 5 sequence of Proteobacterium and 2 sequences of Bacteroidetes were found through denaturing gradient gel electrophoresis (DGGE) results. Sequence closely related to Rummeliibacillus suwonensis strain G20 was detected grows at band BE10, BE11, BE12, BE15, BE16, BE17 and BE18. Meanwhile BE25 and BE26 were found at band after treatment process done.Rummeliibacillus suwonensis is an aerobic, Gram-positive, rod shaped, round-spore-forming bacteria which were isolated from aerobic condition. Keywords: Palm oil mill effluent (POME), anaerobic POME, Denaturing gradient gel electrophoresis (DGGE), and microbial community.

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex Proofs
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

Epistemic Interaction - tuning interfaces to provide information for AI support
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
