大肠杆菌能分解萄葡糖而产酸,当水中有毒物质存在时,产酸作用将受到抑制,因此,水中大肠杆菌生长状况可作为环境污染的毒理学监测方法之一,Anugwelem与Guthrie用平皿计数法研究了不同浓度的西维因对水中大肠杆菌计数的影响,但在六价铬的环境毒理学研究中,没有这方面的报道,本实验的主要目的是观察水体不同浓度六价铬对大肠杆菌生长的影响,从另一侧面为地面水六价铬最大允许浓度的修订提供依据。
Escherichia coli can break down glucose and produce acid, when the presence of toxic substances in the water, acid production will be inhibited, therefore, the growth of E. coli in water can be used as toxicological monitoring of environmental pollution, Anugwelem and Guthrie with plate count Law study of different concentrations of cisplatin in water on the count of E. coli, but in the hexavalent chromium environmental toxicology studies, there is no report in this area, the main purpose of this experiment is to observe the water of different concentrations of hexavalent chromium on the large intestine Bacilli growth from the other side of the surface water hexavalent chromium maximum allowable concentration to provide the basis for revision.
