Anti-Bacterial and Anti-Dermatophytic Activity of Extracellular Secondary Metabolites of Streptomyces glaucescens NTSB-37 Isolated from Lichen Parmotrema perlatum (Huds.) M. Choisy in Kolli Hills, Tamil Nadu, India.

Lichen-associated endophytic Actinobacteria, particularly Streptomyces species, are recognized for their production of bioactive secondary metabolites with significant pharmaceutical potential. With the escalating prevalence of diseases, Streptomyces species are being investigated for its natural source of antimicrobial compounds for new antibiotics. This study focuses on the bioactive properties of secondary metabolites from lichen-associated endophytic Actinobacteria, focusing on Streptomyces glaucescens NTSB-37 isolated form lichen, Parmotrema perlatum (Huds.

Isolation and Characterization of Probiotic Bacteria from Traditional Foods.

A probiotic is a live bacterium that, when given in sufficient proportions, helps to improve the host's gut health. Kimchi and pearl millet, two traditional foods, were used to isolate probiotic bacterial strains. This study's primary goals were to isolate, identify and analyse the microorganisms for potential probiotic traits, tolerance to gastrointestinal environments, and antimicrobial activity, and produce probiotic capsule.

Breeding rice for yield improvement through CRISPR/Cas9 genome editing method: current technologies and examples.

Unlabelled: The impending climate change is threatening the rice productivity of the Asian subcontinent as instances of crop failures due to adverse abiotic and biotic stress factors are becoming common occurrences. CRISPR-Cas9 mediated genome editing offers a potential solution for improving rice yield as well as its stress adaptation. This technology allows modification of plant's genetic elements and is not dependent on foreign DNA/gene insertion for incorporating a particular trait.

Production, optimization and characterization of partially purified anti-mycotic compound from marine soil derived streptomycetes originating at unexplored region of Bay of Bengal, India.

Sixty-eight morphologically distinct isolates of marine actinomycetes were derived from seashore, mangrove, and saltpan ecosystems located between the Palk Strait and Gulf of Mannar region, Bay of Bengal, Tamilnadu. Twenty-five (36.8%) isolates exhibited anti-mycotic activity against Candida albicans and Cryptococcus neoformans in preliminary screening, and 4 isolates with prominent activity were identified and designated at the genus level as Streptomyces sp.
