Microbial fuel cells often produce more electrical power with mixed cultures than with pure cultures. Here, we show that a coculture of a nonexoelectrogen (Escherichia coli) and Geobacter sulfurreducens improved system performance relative to that of a pure culture of the exoelectrogen due to the consumption of oxygen leaking into the reactor.
微生物燃料电池通常在混合培养物中产生比纯培养物更多的电力。在这里,我们表明,由于反应器中泄漏的氧气的消耗,一种非产电菌(大肠杆菌)和脱硫弧菌的共培养物改善了系统性能,优于产电菌的纯培养物。
