This study developed sweet potato media (SPM) as an alternative medium for cultivating Lactobacillus bacteria using sweet potatoes as the basic nutrient component. Three SPM were formulated with varying concentrations of nitrogen sources. Ten Lactobacillus strains were cultured in MRS broth and the three SPM to analyze growth, pH, and acidity. Results showed that SPM2, containing intermediate nitrogen levels, supported Lactobacillus growth equivalent to MRS broth based on growth curves, bacterial populations, pH maintenance above 4.4, and acid production. Thus, SPM2 is a suitable low-cost alternative to MRS for cultivating Lactobacillus.

Expression of Genetically Engineered Chitinase Gene of Pyrococcus furiosusIJERDJOURNAL
ABSTRACT: Wild-type Pyrococcus furiosus is most likely unable to grow on chitin in the natural biotope due to a nucleotide insertion which separates the chitinase gene into two ORFs, whereas a genetically engineered strain with the deleted nucleotide is able to grow on chitin. In the latest studies, the recombinant enzyme activity against the crystal chitins was examined. But there are still some conflictions. In our study, to shed a light on whether the construct composed of a catalytic domain and a chitin binding domain show any activity against crystalline chitin, the construct was created in the pET 28b (+) expression vector and expressed in Escherichia coli. The chitinase with an approximately 55 kDa molecular weight was determined. The activity of the enzyme was measured spectrophotometrically. Despite the presence of enzyme activity against the colloidal chitin, no significant activity against the crystal chitin has been measured.

This document summarizes a study on bacterial transformation. It discusses how plasmids can contain genes that provide resistance to bacteria in foreign environments. The experiment introduces an ampicillin-resistant plasmid to E. coli through a process called transformation. Transformation incorporates foreign DNA into a host cell's genome. The experiment uses E. coli as the host, a plasmid as the vector to transfer DNA, and tags the transformed cells to identify them. The objectives are to observe bacterial transformation and demonstrate a change in phenotype from uptake of plasmid genes.
This document summarizes a plasmid lab report that used pUC19 plasmids as the vector for E. coli transformation due to its small size, high uptake efficiency, and fast replication time. Key features of pUC19 include an origin of replication and multiple cloning sites. Transformed E. coli were able to grow on agar plates containing ampicillin due to the plasmid containing an ampicillin resistance gene. Non-recombinant E. coli colonies were blue due to expression of the lacZ gene, while recombinant colonies were white due to insertion of the CIH-1 gene within the multiple cloning sites.

- The pVAOMP38 plasmid was transfected into seabass kidney cells in vitro and shown to express.
- Fish were vaccinated by feeding with chitosan-pVAOMP38 nanoparticles, chitosan-empty vector, or chitosan alone. The fish were later challenged with V. anguillarum to evaluate vaccine efficiency.
Recombinant Antibody Production: Current Methods and a Novel Antibody Generat...InsideScientific
Dr. Yuning Chen discusses strategies involved in recombinant antibody production and introduces a novel antibody expression platform to facilitate antibody library generation.
Antibodies are bio-macromolecules that bind to their corresponding antigens with exceptional specificity and affinity. They are the foundation of modern biopharmaceuticals and are widely used as therapeutics, diagnostic agents, and tools for biomedical research. Antibodies are derived from methods such as hybridoma, phage-display, and B cell sorting, and produced mainly via recombinant expression.
In this talk, Dr. Yuning Chen from Sino Biological reviews strategies involved in recombinant antibody production, particularly aspects such as construct design, culture condition optimization, and purification methods to provide the audience with a gateway to the field of recombinant antibody expression, technology, and optimization. He also introduces a novel high-throughput antibody expression platform to facilitate antibody library generation and the identification of suitable candidates for further development.
Key Topics Include:
- What are antibodies and what is their role in modern biotechnology?
- Recombinant antibody expression: host systems and general workflow
- Strategies for recombinant antibody construct design
- Methods for optimal recombinant antibody expression and purification
- Applications of a recombinant antibody generation platform for research and therapeutic antibody production
Production of recombinant proteins through fermentation technology involves several key steps:
1. Selection of a host cell, such as E. coli or yeast, for gene expression. Prokaryotic and eukaryotic cells each have advantages and disadvantages as hosts.
2. Cloning the gene of interest into an expression vector and transforming it into the host cell. Coordinated expression of multiple genes may be required to produce complex proteins.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
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:
