摘要：

为了恢复遭受严重有机污染北方季节性河流自净能力,以河北某典型黑臭河流为研究对象,采集其河道底泥和水样,采用乳酸菌、酵母菌、放线菌和硝化细菌专性培养基对底泥中的微生物进行富集、分离、纯化,获取了15株有机污染物降解菌,对其中的6株优势菌采用脂肪酸谱图分析进行了鉴定,这6株菌最终鉴定为黄杆菌属(Flavobacterium)、微球菌属(Micrococcus)、乳杆菌属(Lactobacillus)、小单孢菌属(Micromonospora)、假丝酵母菌(Candida)、硝化球菌属(Nitrococcus)。为了提高菌株的降解与适应能力,采用定向富集液进行菌群复配,得到复合菌,复配试验表明,菌群最佳配比为乳酸菌1. 0%、酵母菌0. 5%、放线菌2. 0...

摘要(英文)：

In order to restore the self-purification capability of the northern seasonal river seriously contaminated by organic pollutants, a typical black-odor river in Hebei Province of North China was taken as the study object, its sediments and water samples were collected, and the culture media specifically for lactobacillus, yeast, actinomycetes, and nitrobacteria were adopted to enrich, isolate, and identify the microbes in the samples. A total of 15 organic pollutants-degrading bacteria strains were isolated, and 6 dominant bacterial isolates of ...
