Caboxamycin, a new benzoxazole antibiotic, was detected by HPLC-diode array screening in extracts of the marine strain Streptomyces sp. NTK 937, which was isolated from deep-sea sediment collected in the Canary Basin. The structure of caboxamycin was determined by mass spectrometry, NMR experiments and X-ray analysis. It showed inhibitory activity against Gram-positive bacteria, selected human tumor cell lines and the enzyme phosphodiesterase.

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.
