Abstract

Abstract: Actinomyces T151, isolated from soil in Hainan province, was identified and screened for antimicrobial activity. T151 was designated as a new strain of Streptomyces according to the observation of SEM morpholiogical and analysis of 16S rDNA sequence. Its fermentation broth exhibited inhibition effect against Escherichia coli, Bacillus subtilis and Rhizopus. The fermentation broth was still owned high antimicrobial activity under 100℃ for 30 min or pH5-11.

Key words: Actinomyces, 16S rDNA, Streptomyces, Antimicrobial activity
