Molecular analysis of cocultures. (a) Relative transcript abundances of the formate dehydrogenase gene (fdnG), the hydrogenase gene (hybA), and the housekeeping gene recA in P. carbinolicus-G. sulfurreducens cocultures as determined by RT-qPCR. Results are the means and standard deviations for triplicate cultures. (b) Western blot analysis of OmcS in equivalent cell protein of G. sulfurreducens grown with fumarate as the electron acceptor or ethanol-fumarate cocultures of P. carbinolicus-G. sulfurreducens or G. metallireducens-G. sulfurreducens cocultures.
