为了筛选针对畜禽养殖污水的高效絮凝菌,试验通过富集、分离、纯化和絮凝活性测定,从绍兴县中大畜牧有限公司(生猪饲养繁育)氧化塘的污水和浅层底泥中筛选絮凝菌,通过形态学、生理生化反应和16S rD NA测序,对絮凝能力最强的菌株进行鉴定。结果表明:从养猪场氧化塘的污水和浅层底泥中分离筛选到7株絮凝菌,其中C4絮凝活性最强,鉴定为解木糖赖氨酸芽胞杆菌(Lysinibacillus xylanilyticus)。
In order to screen efficient flocculation bacteria against livestock and poultry breeding wastewater, flocculation was screened from sewage and shallow sediment of oxidation pond of Shaoxing County Zhongda Animal Husbandry Co., Ltd. (pig breeding and breeding) by enrichment, separation, purification and flocculation activity determination The strains with the highest flocculation capacity were identified by morphological, physiological and biochemical reactions and 16S rD NA sequencing. The results showed that seven flocculating bacteria were screened from the sewage and shallow sediment of the oxidation pond in pig farms. Among them, the highest flocculation activity of C4 was identified as Lysinibacillus xylanilyticus.
