During the investigation, soil actinomycetes were isolated from Kathlekanu swamp forest and the crude ethyl acetate extract from the potent isolate KF15 was analysed with GC-MS and HPTLC to identify bioactive metabolites. The crude extract was examined for in-vitro antifungal activity on pathogens of chilli; MTT cytotoxicity assay was performed against HeLa cell line to determine the anticancer potential. The isolate Streptomyces sp. strain KF15 exhibited antagonistic activity against fungal pathogens by inhibiting growth and altering growth pattern with increased antimicrobial activity in dose-dependent manner. GC-MS revealed many bioactive compounds and HPTLC depicted metabolite fingerprint. The IC of 99.85 µg/ml indicated the high potential of KF15 extract to prevent proliferation of HeLa cells. Therefore, the findings of this study indicate that the crude extract from Streptomyces sp. strain KF15 contains antifungal and anticancer metabolites; further study on purification could help in controlling many fungal diseases as well as cervical cancer in humans.

Under semi-open brewing conditions, traditional often suffers from unstable flavor quality, including occasional delayed bitterness. To address this issue, a yeast strain, SC-6, was screened for its ability to reduce delayed bitterness. The effects of SC-6 on the flavor and microbial composition of exhibiting high levels of delayed bitterness were also investigated.

Background: Actinomycetes are a well-known example of a microbiological origin that may generate a wide variety of chemical structures. As excellent cell factories, these sources are able to manufacture medicines, agrochemicals, and enzymes that are crucial.
Results: In this study, about 34 randomly selected Streptomyces isolates were discovered in soil, sediment, sea water, and other environments.

Medicinal plants often harbour various endophytic actinomycetia, which are well known for their potent antimicrobial properties and plant growth-promoting traits. In this study, we isolated an endophytic actinomycetia, A13, from the leaves of tea clone P312 from the MEG Tea Estate, Meghalaya, India. The isolate A13 was identified as Streptomyces sp.

Doramectin, a 16-membered macrocyclic lactone that is widely used in the treatment of mammalian parasitic diseases. Doramectin was produced by mutant using cyclohexanecarboxylic acid as a precursor. As a semi-synthetic insecticidal agent produced, the production of doramectin was low, which could not be satisfy the demands of industrial fermentation.
