高效中等嗜热菌自然界选育方法探索研究

Exploratory Research on Isolation of High-efficiency Moderate Thermophilic Bacteria from Nature

通过采样、富集、分离纯化、菌种鉴定等系列措施 ,建立了从自然界选育高效浸矿菌的有效方法。在研究的过程中 ,确定了样品采集原则 ,培养基选择的基本方法 ,以及对菌种分离及鉴定的初步手段。通过探索性试验 ,选育分离出一株中等嗜热菌CLJ菌 ,并对其进行了初步鉴定 。

Application and isolation of moderate thermophilic bacteria become a research hotspot during recent years. In this paper we discuss the fundamental of sample collection,analyze the culture medium selection and establish the effective method of isolating moderate thermophilic bacteria from nature. The moderate thermophilic bacteria isolated from nature named CLJ bacteria. During the test we deeply express the characteristic of physiological ecology, and test ability of bio-leaching. After the study we establish a effective method of isolating moderater thermophilic bacteria from nature.
