广西湖润锰矿床的共生生金菌的分离与鉴定

ISOLATION AND DETERMINATION OF METALLOGENIUM SYMBIOTICUM IN HURUN MANGANESE DEPOSIT OF GUANGXI

从锰矿床中分离出一种氧化锰的细菌－－共生生金菌、该菌嗜温、好氧，是一 化能有机营养型细菌其适宜于ＰＨ６－８的环境中生长，生长具有周期性，与锰作用也表现出阶段性，是氧化锰的主要生物因素。

Metallogenium symbioticum, a manganese-oxidizing bacterium, was isolated from manganese deposit. It isa budding-breeding, thermophilic and aerobic oxidizing bacterium, and also is a chemoheterotrophic bacterium. It isfit to grow in the pH6--8 environment. Its growth shows periodic, and the interaction with manganese also showsperiodic. It is the main biofactor for oxidizing manganese.
