What Happens When You Mix Chitosan and Poultry Litter?

LPE Learning Center

http://www.extension.org/67731 The solubility of phosphorus (P) and low nitrogen(N):P ratio of poultry litter present environmental challenges when using this resource to supply nutrients to crops and forages. Here, we explore the use of chitosan to reduce water extractable P (WEP) in poultry litter and potentially increase the N:P ratio. Chitosan is derived from chitin, which is a waste product from the commercial shellfish industry; chitin is processed into chitosan through deacetylation, removing acetyl groups from this long-chained molecule. Chitin has been successfully used in manure separation and flocculation in wastewater treatment processes, as well as immobilizing algae in wastewater streams to uptake nutrients.

adsorption of methylene blue onto xanthogenated modified chitosan microbeads

Siti Nadzifah Ghazali

Methylene Blue (MB) is thiazine dyes that widely use to color product in many industry such as textile, printing, leather, cosmetic and paper. Xanthogenated-Modified Chitosan Microbeads (XMCM) is use to observe the new alternative adsorbent in removing MB from water body through adsorption process. The interactions between MB and functional group in XMCM were confirmed by Fourier Transform Infrared (FT-IR) spectra. Several parameters that influence adsorption ability such as the effect of adsorbent dosage of XMCM and the effect of initial pH of MB aqueous solution were studied. This study were done at optimum condition which is at pH 4 of initial pH of MB solution, 0.01 g of initial XMCM dosage, 6 hours stirring time and temperature of (30 ± 2 ℃). The adsorption data fit well Langmuir model more than Freundlich model. Based on Langmuir model, the maximum monolayer adsorption capacity of MB was 21.62 mg g-1 which indicated that XMCM can be a new alternative adsorbent for removing MB.

SSR Institute of International Journal of Life Sciences

ABSTRACT In the present study, Chitin has been extracted from Agaricus bisporus (Button mushroom). The obtained chitin was converted into the more useful chitosan and the crude chitosan extract was measured for its absorption maxima by UV Spectrophotometer and the maximum peak at 265nm was observed. FT-IR spectroscopy was done to identify the functional groups present in the chitosan which was analyzed between the ranges of 4000–400 cm-1. Chitosan was characterized by significant amide bands at 3265.49 cm−1. The absorbance bands of 1402.25, 1153.43, 900.76 and 445.56 cm-1 indicates CH2 stretching, CH stretching, C=O stretching in secondary amide respectively which confirms the structure of chitosan. The antioxidant activity of chitosan was determined by DPPH free radical scavenging assay and the value gained is 65.90% at 250 mg/ml which is due to the presence of rutin, gallic acid, caffeic acid and catechin in the phenolic composition of Agaricus bisporus. Finally, in vitro antibacterial screening of chitosan from Agaricus bisporus was performed against selected clinical isolates and the zone of inhibition shows highest activity in Bacillus subtilis, P. aeruginosa followed by K. pneumonia, and Acinetobacter baumannii. These findings suggest that the Agaricus bisporus act as the potential source to produce eco-friendly chitin and chitosan in the development of drugs, artificial bone and raw material for food industries in near future.

CULTIVATION OF OSCILLATORIA SP IN DAIRY WASTE WATER IN TWO STAGE PHOTO BIOREA...

civej

This paper presents an integrated approach to cultivate microalgae in dairy wastewater and to investigate the capability of the organism for biodiesel production. The present study was carried out using tolerant strains of microalgae collected from dairy effluent treatment plant, Kochi. Selected blue green algal strains were mass cultured in the laboratory and acclimatized using different concentrations of synthetic effluent. Blue green algal filaments were immobilized inside the primary and secondary photobioreactors. The experiment was conducted in two stages including batch and continuous treatment. The stage 1 of the experiment was designed for the reduction of physical impurities and the nutrients. Stage 2 was designed mainly for the cultivation of blue green algae in dairy waste water by utilizing the extra nutrients . Reduction of 94 -99.5% in phosphate was observed after 48 h of treatment in the primary and secondary photobioreactors. The level of phosphate, total hardness, ammoniacal nitrogen in the MSE was reduced by 97%,93 %, 81% respectively. BOD was reduced to 370mg L-1 from 1500 mg L-1 after 48 hrs of treatment in the primary reactor. COD was reduced to 85 mg L -1 from an initial value of 1500 mg L -1 from medium strength effluent (MSE) and 90-95 % removal of COD was also obtained from high strength effluent(HSE) during the study period. Biomass developed within the reactor was harvested at every 15 days intervals from the secondary reactor and analyzed for lipids and fattyacids. Presence of C14:0, C16:0,C18:0, C18:1 and C18:2 fatty acids strongly supports its abilility for biodiesel production.

preparation and foliar application of oligochitosan

IJEAB

Oligochitosan with weight average molecu-lar weight (Mw) of 5000 g/mol was prepared by gamma Co-60 radiation degradation of 4% chitosan solution containing 0.5% H2O2 at 21 kGy. Nanosilica with size of 10 – 30 nm was synthesized by calcination of acid treated rice husk at 700o C for 2 h. The mixture of 2% oligo-chitosan-2% nanosilica was prepared by dispersion of nanosilica in oligochitosan solution. Oligochitosan, nanosilica and their mixture were characterized by gel permeation chromatography (GPC), transmission electr-on microscopy (TEM), X-ray diffraction (XRD), energy dispersive x-ray spectroscopy (EDX), Ultraviolet-visible spectroscopy (UV-Vis), and Furrier transform infrared spectroscopy (FT-IR). Effect of foliar application of oli-gochitosan and oligochitosan-nanosilica on soybean seed yield was conducted in experimental field. Results indi-cated that soybean seed yield increased 10.5 and 17.0% for oligochitosan and oligochitosan-nanosilica, respect-tively for the control. Radiation degraded oligo-chitosan and its mixture with nanosilica can be potentially used for cultivation of soybean with enhanced seed yield.

Phycoremediation is a green technology that supports the direct use of living green microalgae for in situ, or in place removal, degradation, of contaminants in soils, sludge, sediments, surface water and ground waters by the mechanisms of bio-transformation, bio-accumulation, bio-concentration, bio-sparging. It can be said by the current study that microalgae has a great potential for the treatment of industrial and municipal wastewaters as compared to the chemical treatments available commercially. Biological systems are much more efficient in cleaning the excess nutrients from the waste water followed by generation of valuable biomass which can be applied in the food, fertilizer, energy production as use of inorganic chemicals like lime and ferrous sulphate generates huge amount of sludge in textile industries, but on the other hand static anaerobic treatment using acclimatized MLSS gives better colour reduction with zero sludge generation. Microalgal cells can be used in free form to treat waste waters containing high C.O.D., high ammonical nitrogen and high TDS. It not only provides a better reduction of chemicals from wastewaters but it also helps to reduce the operational cost of ETP. Microalgaes not only helps to remediate industrial waste waters but also to treat sweage water and to restore natural water bodies like lakes and ponds. As they are active in remediating the chemicals but also it shows an antagonistic effect against some pathogenic germs like total coliforms and fecal coliforms. These microalgal cells can also be combined with bacterial biomass of activated sludge process to develop an Algal-Bacterial consortium (ALBA) for better enhancement in the reduction of chemicals from the wastewaters as this symbiotic relation of algae and bacteria provides high satiability of the microalgae along with MLSS and faceable in terms of price and economy for instance the bacterial biomass provides carbon dioxide to algal cells for photosynthesis and in return the bacteria acquires oxygen from algae. The harvested biomass from the ETP’s can be used as bio-fertilizers as it consists of appropriate ratio of vital macro and micro nutrients like N,P,K etc. which enhance the growth of plantlets. It can also be used as aqua feeds for shrimps, fishes and molluscs. Furthermore these microlgal cells are non-toxic in the environment as it becomes a part of food chain and do not cause eutrophication. Therefore, micro-algal based treatment is most suitable for the treating the waste waters and restoring the natural water bodies as compared to other chemical treatments.

inventionjournals

Chitin is a biodegradable,long, linear chain polymer found naturally abundantly in the marine and terrestrial environments. In this study, the capability of Chitin to delay the ripening of fruits is proved by coating chitin composites in three concentrations (low0.25%, Medium0.5%, High0.75%) on Apple and Tomato samples. A comparison study was carried out between three groups of samples which were coated with Glucose/Chitosan Medium, Glucose/Chitosan medium added chitinase enzyme and Chitosan Silver Nano composites respectively. Edible Chitosan coating effected positively on the samples and the coated samples showed significant difference in all physiochemical parameters than the control (uncoated). The results showed that all the groups showed similar effects in the quality parameters such as pH, phenolic content and antimicrobial activity of the samples. The third group comprising of the Apples and Tomatoes coated with Chitosan silver Nano composites showed significant time delay of ripening of the fruits in comparison with the other two groups.Chitosan coatings can be used for storage of highly perishable fruits as it had showed increase in the shelf life of the samples used in the study. They significantly control the moisture content between the fruits and the external environment thus proving effective in preventing fungal contamination of the fruits.

Dr.Ir. Gatot Trimulyadi Rekso, M.Si- Indonesia

Dr.Ir. Gatot Trimulyadi : The adsorption behavior of chitin and its concerns with various degree of deacetylization. This high adsorption capacity was ascribable primarily to its remarkable hydrophilicity in cooperation with the relatively high amino group content. It is indicate that the importance of hydrophlicity and suggest that, in order to develop adsorbents of high capacity, it is make indicate the importance of hydrophilicity essential to make chitin derivatives highly hydrophylic and yet insoluble in water.

Climate Impact of Software Testing at Nordic Testing Days

Kari Kakkonen

My slides at Nordic Testing Days 6.6.2024 Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Epistemic Interaction - tuning interfaces to provide information for AI support

Alan Dix

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.

Securing your Kubernetes cluster_ a step-by-step guide to success !

KatiaHIMEUR1

Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster. However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks. In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

Removing Uninteresting Bytes in Software Fuzzing

Aftab Hussain

Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process. In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds. - These are slides of the talk given at IEEE International Conference on Software Testing Verification and Validation Workshop, ICSTW 2022.
