Subsequently through the soil(sterilized or not) culture, the effects of carbon source and soil structure on the isolated bacteria growth and formation of WSA were studied by wet sieve and chloroform fumigation extraction methods.

• 最后通过灭菌与不灭菌条件下的土壤培养，采用湿筛、氯仿熏蒸等方法，进一步研究了碳源物质、土壤机械组成对菌株在土壤中的生长以及对土壤水稳性团聚体形成的影响。
