摘要 在厌氧-缺氧环境下,从磷矿废水中筛选出一株高效的厌氧型聚磷菌,命名为AP06.对该菌株进行了生理生化研究及16S rDNA序列分析,并对该菌株的聚磷效率和影响聚磷特性的因素进行了研究.结果显示:菌株初步鉴定为Aeromonas sobria,聚磷效果最佳的pH值为7,温度为30℃,磷源为KH_2PO_4,接种量(V/V)为7%,菌株的聚磷效率为86.1%. A high-efficiency phosphate-accumulating bacterium strain named AP 06 was isolated from phosphorite wastewater .The strain was identified according to its physiological and biochemical characteristics , and its 16S rDNA sequence .The biological phosphorus removal characteristics of this strain were also studied .The results showed that the strain was identified as Aeromonas sobria.The phosphorus effect was best with removal rate of 86.1% when pH of the fermentation medium was 7, culture temperature was 30 ℃, KH2 PO4 was used as phosphorus source , and the inoculum concentration was 7%( V/V) .
