摘要
[ Objective] To lay the basis for further studying bioactive substances in myxobacteria. [ Method] A total of 35 samples including fresh water, mud, rabbit dung, sheep dung, weathered rock and rotten wood were collected from districts and counties of Chengdu. After pretreatment, the myxobacteria were isolated and purified using different methods. Vegetative cells, myxospores, fruiting body and colony morphology of these myxobacteria strains were observed. E ResultJ Forty-two myxobacteda strains were isolated and purified. They were classified into seven genera including Myxococcus, Angiococcus, Chondromyces, Sorangium, Melittangium, Stigmatella and Archangium. The plating efficiency of myxobacteria was highest in the fresh water samples. [ Conclusion] Abundant myxobacteria resource is found in fresh water.
