Abstract:
Through experiment on single or both of the two preponderant funct ional bacteria, AB- ZH01 and SRB- ZH07 isolated from acidog enic bio-reactor, ecological relat ion of microbe in acidog enic desulfate bio-reactor were studied. T he order of removal rate of SO 2- 4 for SRBZH07 using all the subst rates is lact ic acid> propionate> butyric acid> acet ic acid> glucose; the OD600 nm order of AB- ZH01 culture solut ion using all the subst rates as sole carbon source is g lucose> lactic acid> butyric acid> acetate acid> propionate. Protocooperation betw een ABZH01 and SRB- ZH07 w as found. AB- ZH01 can accelerate deg radation of glucose and pro vide subst rates for SRB- ZH07. The produced H2S throug h metabolism of SRB- ZH07 can re st rain the grow th of AB- ZH01. When the amount ratio of AB- ZH01 and SRB- ZH07 is 0. 5, theSO 2- 4 removal rate is the greatest .
