Abstract:The absolute alcohol extraction of Streptomyces 702 from shaking-flask fermentation broth was diluted in 200 times as the Bio-antiseptic 702. To assay its effects on anti-bacteria, anti-moulds and anti-yeasts, 6 different kinds of bacteria, 9 different kinds of moulds and 4 different kinds of yeasts were used as indicator strains, respectively. The results showed that the antimicrobial rates on these indicator strains were 100% ,except for E.coli, which was 93%; when the medium plates were inoculanted in the air , the antimicrobial rates of Bio-antiseptic 702 could also reach 100%.
Keywords:Bio-antiseptic 702  Streptomyces 702  antimicrobial assay
