Project description:Propionate accumulation is an important bottleneck for anaerobic degradation of organic matter. We hypothesized that propionate conversion by a novel coculture of Syntrophobacter fumaroxidans and Geobacter sulfurreducens can be an alternative strategy for propionate oxidation coupled to Fe(III) reduction. In this study, we successfully cocultured S. fumaroxidans and G. sulfurreducens on propionate and Fe(III). Proteomic analyses of this coculture provided insights into the underlying mechanisms of propionate metabolism pathway and interspecies electron transfer mechanism. Our study can be further useful in understanding syntrophic propionate degradation in bioelectrochemical and anaerobic digestion systems.
