Differential anaerobic oxidation of benzoate in <i>Geotalea daltonii</i> FRC-32.

ABSTRACT: The efficient carbon source utilization in dynamic environments, including anoxic subsurface contaminated by aromatic compounds, is a challenge for anaerobic bacteria such as Geotalea daltonii strain FRC-32. The aim of this study was to elucidate the metabolic pathways employed by G. daltonii FRC-32 during anaerobic benzoate oxidation in the presence of acetate, a key intermediate in anaerobic organic matter degradation, to predict carbon source transport and utilization strategies. Simultaneous carbon source oxidation and monoauxic growth were observed in G. daltonii FRC-32 cultures grown on 1 mM benzoate + 5 mM acetate, 1 mM benzoate + 2 mM acetate, and 2 mM acetate spiked with 1 mM benzoate. Sequential carbon source oxidation and diauxic growth were observed
