| 摘 要： | 目的]为光合细菌的大规模培养提供技术资料。方法]从池塘底泥中分离出多株光合细菌,通过分离鉴定,对其中1株生长迅速、各方面性状良好的紫色非硫细菌psb-4进行大规模培养和降解污水试验,并研究pH值及Cu^2＋、Pb^2＋对该菌株净化水质的影响。结果]psb-4为革兰氏阴性菌,可在光照、厌氧、微好氧条件下生长,适合大规模培养;当温度适宜时,psb-4具有良好的培养特性,培养液中细菌最高浓度超过1.0×10^10个/ml,同时,光照是psb-4生长的重要影响因子;pH值为6-9时,psb-4均具有一定的降解污水中氮、磷的能力,其中pH值为8时,该菌株对氮、磷的降解效果最好;psb-4对Cu^2＋、Pb^2＋具有一定的耐受性,可在重金属污染不严重的污水中应用。结论]psb-4可在一定pH值和重金属离子浓度范围内降解污水中的氮、磷。
