枯草芽孢杆菌和光合细菌对鹅场养殖污水净化效率的研究

鹅养殖污水中的有害细菌和内毒素可严重影响鹅的生产性能，甚至引起发病，导致死亡．为探索鹅场养殖污水的净化方法，本研究以枯草芽孢杆菌（Ｂａｃｉｌｌｕｓｓｕｂｔｉｌｉｓ）和光合细菌为试验菌种，探究枯草芽孢杆菌和光合细菌通过单独或协同作用对鹅场养殖污水中总细菌数量、大肠杆菌和沙门氏菌的抑制效果．结果表明，枯草芽孢杆菌和光合细菌能够有效的抑制水体中大肠杆菌和沙门氏菌的繁殖，且两者协同作用抑制效果更为明显．二者对污水中大肠杆菌和沙门氏菌的抑制作用具有一定的时间限制性，在处理后７ｄ内对大肠杆菌的抑制效果最佳．因此，添加枯草芽孢杆菌和光合细菌能够显著净化水禽养殖水质，有效改善养殖环境．

Purification effects for foul water treated with Bacillus subtilis and Photosynthetic bacteria

The pathogenic bacteria in the foul water from goose farm could affect the production performance of goose, even cause diseases and death. In order to explore the purification methods for foul water from goose farm, Bacillus subtilis and Photosynthetic bacteria were used to know about the purification effects for foul water from goose farms in this study. The evaluation index includes the total number of bacteria, the number of Escherichia coli and Salmonella in foul water treated with B. subtilis and Photosynthetic bacteria. The results showed that B. subtilis and Photosynthetic bacteria can inhibit the proliferation of E. coli and salmonella effectively, more efficiently treated with B. subtilis and Photosynthetic bacteria together. However, the inhibition effect is time restrictive and the most inhibition effect in 7 days after treatment. In conclusion, B. subtilis and Photosynthetic bacteria can be used to treatment with foul water from goose farms to improve the breeding environment.
