摘要: 通过对河北、云南、青藏高原不同地区的粘细菌进行生态多样性研究,从42个样品中分离得 到了10个属(Archangium、Myxococcus、Cystobacter、Corallococcus、Melittangium 、Sorangium、 Polyangium、Chondromyces、Angiococcus、Stigmatella)的150余株粘 细菌,其中包括一些尚未有描述的菌株,有待鉴定。根据这些菌株的子实体结构、菌落形态 、 营养细胞、粘孢子形态等特征将它们初步鉴定到属。对这些特有自然生态环境的粘细菌按不 同地点、植被、营养基质进行统计比较,结果表明粘细菌生态分布极为广泛,具有丰富的生 态多样性。以上结果为粘细菌生物资源的有效开发利用奠定了基础。

Abstract: Through study on ecological diversity of myxobacteria in some areas of Hebei , Yunnan , and the Qinghai-Tibet Plateau , more than 150 st rains of 10 genera ( Archangium , Myxococcus , Cystobacter , Corallococcus , Melit tangium , Sorangium , Polyangium , Chondromyces , Angiococcus and Stigmatella) of Myxococcales were isolated from 42 samples , including some special strains that have never been described before. These strains were preliminary identified to generic level by their fruiting bodies , swarms , myxospores and vegetative cells. Comparison of myxobacteria statistics with the different sites , vegetations and nut rition sources of these special habitat sshows wide distribution and variety of ecological diversity of myxobacteria. This sets a strong base for developing and utilizing myxobacteria efficiently.
