Abstract

Penicisteroid C, a new polyoxygenated steroid was isolated from co-cultivation of Streptomyces piomogenus AS63D and Aspergillus niger using solid-state fermentation on rice medium. Additional diverse eleven known metabolites were identified: Fumigaclavine C, fumiquinazoline C, physcion, methylsulochrin, methyllinoleate, glycerol linoleate, cerebroside A, thymine, adenine, thymidine and adenosine. The structure of penicisteroid C was determined by HRESIMS, 1D and 2D NMR data. The antimicrobial and in vitro cytotoxic activities of the microbial extract and penicisteroid C were reported as well.

Keywords: Antimicrobial activity; Aspergillus niger; Co-cultivation; Cytotoxicity; Penicisteroid C; Sterol; Streptomyces piomogenus.
