摘　　要：实验选用了光合细菌、芽孢杆菌、酵母菌、保加利亚乳酸菌为主要菌种按一定比例配制出4种复合菌,并研究了这4种复合菌对水产养殖水体的净化作用.结果显示:"光合细菌组"在提高水体的溶氧量方面效果极显著,比对照组提高了29%;"芽孢杆菌组"、"乳酸菌组"和"光合细菌组"在降低氨氮方面效果极显著,分别比对照组降低了80%,78%和65%;在降低pH值方面,"芽孢杆菌组"和"乳酸菌组"作用明显,且不引起PH值剧烈波动.结果表明:这几种微生物都可用于养殖水体的净化,可根据具体水质变化加以应用.The four beneficial microorganisms Photosynthetic Bacteria, Bacillus, Yeast and Bulgaria Lactobacillus strains were selected to composite four compound bacteria, and the four compound bacteria were studied on purification aquaculture water. Results showed that ＂Photosynthetic Bacteria＂ unit had significant difference in raising the water＇s dissolved oxygen content, which increased 29 % compared to the control group.＂ Bacillus＂, ＂Bulgaria Lactobacillus＂ and ＂Photosynthetic Bacteria＂ unit had significant difference in reducing ammonia content, which dvcreased 80%, 78% and 65 % compared to the control group respectively.＂ Bacillus＂ and ＂Bulgaria Lactobacillus＂ unit had significant difference in controlling the pH of the water, which would not cause the pH value to fluctuate drastically. It is suggested that all four beneficial microorganisms can be used to purify aquaculture water according to the changes of water quality.
