It is dilution spread and repeat dish sandwish cultivated method with the exellence of dilution spread and embeded growth, and it can help separation and identification of SRB. The method has simple operation and less equipment. And using this method, the natural SRB drop was successfully gained, and small agar pieces containing SRB drop were acquired in easiness. The brief SRB transfering operation in strict anaerobic condition was indeed realized. Fig 1, Ref展开更多
