چکیده
<p>Dual-chamber microbial fuel cell (MFC) was constructed to treat heavy metal wastewater (Pb2+ solution). The results showed the maximum voltage, electric power density and pb2+ removal were 9.6 mV, 371.0 mV/m2 52.3% respectively. effects of different cathode chamber environments on production potential (V, volts) Pb2+ rate strained CD-1 investigated. show that when is soil, voltage 8.88mV, solution, 12.11mV. efficiency metals polluted from near far electrode plate in soil 68.9%, 62.1%, 57.5%, solution 67.46%. It can be concluded chamber. local highest. When used as a chamber, average bacteria, named strain CD-1, electricity bacteria (EPB) dual (MFC), isolated activate sludge identified its morphology, physichemical properties phylogenetic positions. indicated Gram-negative, rod. Oxidase catalase reactions positive. Strain could use gluconate, lactose, D-fructose, L-Arabinose, D-arabinose, acetate, propionate, butyrate, lactate, sucrose glucose, not melibiose, galactose, N-acetylglucosamine, ethanol glycerol.16S rRNA gene sequences analysis most related Ochrobactrum sp. (AJ245941）with homology similarities 98%. Based above results, belonged genus seemed represent novel species.</p>
