养殖水体中大量氨氮、硫化物的产生以及溶解氧的降低严重影响了对虾的正常生长。本文报道了光合细菌在实验室环境中净化水质的情况，结果表明，光合细菌能降低养殖水体中的氨氮和H2S含量，并提高水体中溶解氧的含量。
Aquaculture water, a large number of ammonia, sulfide and dissolved oxygen to reduce the serious impact on the normal growth of shrimp. The paper reports the purification of photosynthetic bacteria in laboratory environment. The results show that photosynthetic bacteria can reduce the content of ammonia nitrogen and H2S in aquaculture water and increase the content of dissolved oxygen in water.
