在鱼虾育苗、养殖,池塘淡水养鱼以及观赏鱼养殖中,使用以牛肉水提取液为主要培养基培养的活菌数大于50亿/mL的活性光合细菌,测定了使用前后水的pH值、COD值、NH3-N、亚硝酸盐、溶解氧等指标,结果表明:与市场出售的光合细菌(活菌数为25亿/mL)相比,活菌数大于50亿/mL活性光合细菌能明显改善水产养殖体系的水质状况。 In fish and shrimp breeding, aquaculture, pond freshwater fish culture and ornamental fish, the use of beef water extract as the main culture medium with viable count of more than 5 billion / mL of active photosynthetic bacteria measured before and after the use of water pH, COD value, NH3-N, nitrite, dissolved oxygen and other indicators, the results showed that: compared with the market of photosynthetic bacteria (viable count of 2.5 billion / mL), the number of viable bacteria is greater than 5 billion / mL of active photosynthetic bacteria Significant improvement of water quality in aquaculture systems.
