西藏索马地区土壤放线菌的初步鉴定

采用常规方法对西藏索马地区高山草原土中放线菌进行了初步鉴定和分类，并对链霉菌属进行了生理生化鉴定。结果表明，该地区放线菌可分为１０个属，以链霉菌属占优势；链霉菌属可分为１２个类群，金色类群占优势。生理生化试验表明，参试菌株淀粉水解，明胶液化能力较强，纤维素分解能力较弱；拮抗试验中抗细菌多于抗真菌菌株，细菌中以抗Ｇ＋细菌为主。

Identification of Soil Actinomyces from Suoma Area in Tibet

The Actinomyces from alpine meadow soil in Tibet was identified and classified by using routine methods,and its physiological and biochemical characteristics were identified.The results showed that the Actinomyces of Suoma Area could be classified into 10 genus with dominative streptomyces ,and then streptomyces into 12 series with dominative S.Aureus .In physiological biochemical test,the test strains had strong ability of starch hydrolysis,geletin liquification and weak ability of cellulose decomposition.In antibiotic test,bacterial resistance was in the majority and G Bacteria were dominative.
