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.
