Biokinetic evaluation of fatty acids degradation in microbial fuel cell type bioreactors

摘要: Biodegradations of Na-lactate and Na-acetate were evaluated in microbial fuel cell (MFC) type bioreactors. Increase lactate concentration from 1,000 to 5,000 mg L−1 enhanced the biodegradation rate 4.6 23.9 mg L−1 h−1. Sequential batch operation MFC rate. With acetate, neither increase nor sequential had a marked effect. Maximum power current densities MFCs operated batch-wise with acetate 3.30 2.28 mW m−2, 48.2 40.2 mA m−2, respectively. In continuously, loading caused pass through maximum value 1,668.2 mg L−1 h−1 (residence time: 1.2 h). Open circuit potential, for continuous 700 mV, 8.10 mW m−2 43.0 mA m−2, Using experimental data, kinetic models growth developed.
