Biologically Synthesized Silver Nanoparticles and Their Diverse Applications.

Nanotechnology has become the most effective and rapidly developing field in the area of material science, and silver nanoparticles (AgNPs) are of leading interest because of their smaller size, larger surface area, and multiple applications. The use of plant sources as reducing agents in the fabrication of silver nanoparticles is most attractive due to the cheaper and less time-consuming process for synthesis. Furthermore, the tremendous attention of AgNPs in scientific fields is due to their multiple biomedical applications such as antibacterial, anticancer, and anti-inflammatory activities, and they could be used for clean environment applications.

Structural Characterisation and Assessment of the Novel RK3 Exopolysaccharide on the Improvement of Cognitive Function in Alzheimer's Disease Mice.

In this study RK3 was isolated from a sugar mill effluent-contaminated soil and utilised to generate a potential polysaccharide with anti-Alzheimer's activity. Traditional and molecular methods were used to validate the strain. The polysaccharide produced by RK3 was purified, and the yield was estimated to be 10.

Antimicrobial and antifungal activity of soil actinomycetes isolated from coal mine sites.

In the current study, twenty-eight soil samples were collected from coalmine sites of Telangana, India. The isolates were purified and identified based on their culture characterization on oatmeal agar, glycerol asparagine agar, yeast extract-malt extract agar, inorganic salt starch agar, and starch casein agar medium. Further, the supernatant of all the isolates were tested for antimicrobial and antifungal activities.
