Khảo sát ảnh hưởng của một số nguồn cacbon và nitơ đến khả năng sinh trưởng và kháng khuẩn của chủng Streptomyces sp. HM9 phân lập từ hải miên.

Abstract

Streptomyces has been known as a source of natural bioactive substances so far. In this present study, the sponge-derived Streptomyces HM9 was optimised with a number of different carbon (C) and nitrogen (N) sources to evaluate the broad-spectrum antibacterial ability. Starch and (NH4)2SO4 were favourable carbon and nitrogen sources to the growth of the strain HM9. Starch and casein were suitable carbon and nitrogen sources for antibacterial activity of strain HM9 against Vibrio, whereas lactose and NH4Cl were beneficial on the inhibition of standard indicator Bacillus subtilis ATCC 6633
