污水中解有机磷微生物的筛选

Screening on Phosphate Solubilizing Bacteria in Sewage

水污染是全球十大环境问题之一,而城镇生活污水的排放则是造成水体磷污染的主要来源之一,以有机磷的形态为主的输入,是引起水体富营养化的关键因素。试验从生活污泥中分离筛选出六株解磷细菌,其中,3、5、6号菌株在培养5天后,仍有较强的解磷能力,分离筛选结果将为今后的研究提供依据。

Water pollution is one of ten global environmental issues,and the discharge of sewage in urban life is one of main sources of phosphorus pollution,input based on organic phosphorus is the key factor to cause eutrophication of water body.This test isolates six phosphate solubilizing bacteria from sewage sludge,No.3 strain,No.5 strain and No.6 strain still have a strong solubilizing ability,this screening results will provide the basis for future research.
