The anaerobic bacterium Megasphaera hexanoica has great potential for caproate production through reverse β-oxidation using lactate, acetate, and butyrate as substrates. This study assessed the effect of acetate concentrations (10-50 mM) on biosynthesis, lactate oxidation, cell synthesis in M. hexanoica. At 30 mM reached 42.83 mM, with an electron efficiency 67.03 % a specific productivity 4.47 gCA·h-1·gDCW-1. Subsequent fed-batch experiments maintained continuous production, achieving 65.21 mM. Bioreactor assays further validated strategy, yielding 65.25 over 180 h. Mechanistic analysis demonstrated that optimized acetyl-CoA flux enhanced caproyl-CoA transferase activity (3.5 U‧mg-1), supporting synthesis. Kinetic modeling Logistic model fit consumption (R2 = 0.991), while Fitzhugh captured 0.991, NRMSE 1.137). findings offer practical insights industrial-scale production.

Wastewater treatment significantly contributes to greenhouse gas emissions, which are further exacerbated by the environmental impact of external chemical additions. In response, microbial electrochemical wastewater refining has gained prominence at interdisciplinary frontier resource recovery and green bio-manufacturing. Significant progress been made in utilizing active electrodes stimulate CO2 fixation rates, applying "binary electron donors" produce high-value-added chemicals, developing novel processes equipment. This review explores various aspects refining, including monitoring water quality, synthesis from diverse carbon sources, deployment pilot-scale systems for generating electricity, hydrogen, methane, as well in-situ remediation. Additionally, it discusses challenges future directions, highlighting importance understanding mechanisms, advancing electrocatalyst engineering, innovating hybrid processes. conclusion, widespread adoption is emphasized sustainable production, ultimately reducing impact.
