胶州湾放线菌的分离及其抗病原微生物的活性检测
ISOLATION OF STRAINS OF ACTINOMYCETES FROM JIAOZHOU BAY AND THEIR ACTIVITIES AGAINST PATHOGENIC MICROORGANISMS
摘要
Abstract
We isolated 224 actinomycetes strains from sea mud samples and 32 strains from seawater samples of the Jiaozhou Bay, China,by using the spread method. The isolates were grouped into 7 groups on basis of their morphological characteristics. Their antimicrobial activities were tested by using the cup-plate method, and the results showed that 7% of the isolates were active against Staphylococcus aureus, 11% against Sarcine lutea, 10% against Escherichia coli, 11% against Bacillus pyocyaneus, 2% against Candida albicans, 5% against Cryptococcus, 6% against Streptomyces viridochromogenes, and 6% against Mucor miehei. Twenty-two percent of isolates were active against at least one of the test organisms. Our data suggests that actinomycetes from the Jiaozhou Bay, China can produce various active metabolites against pathogenic microorganisms, which provids unique and plentiful sources to screen novel natural products for combating diseases in man.关键词
