摘　　要：本文从铁锰矿样品中分离筛选得到一株具有产电能力的细菌,经16S rRNA序列测序鉴定为恶臭假单胞菌,命名为PseudomonasputidaF04,NCBI序列号为MN726711。该菌株在4 g/L蔗糖和中性pH的阳极溶液中,最大面积功率密度达181.8 mW/m2,循环伏安扫描显示该菌体中含有电化学活性物质,为微生物燃料电池处理铁锰废矿提供了科学依据。Anexoelectrogenic bacteriumwas isolated and screened from ferromanganese samples,it was identified asPseudomonasputidaF04 by 16S rRNA sequencing analysis(Gene Bank Accession:MN726711).The strain showed a strong power generation capacity,its maximum area power density of reached 181.8 mW/m2,when 4 g/L sucrose was used as the substrate and the pH of anode solution was neutral.There were electrochemically active substances in the bacteriafromcyclic voltammetry result.It provides a scientific basis for the treatment of ferromanganese ore samples.
