Abstract:
:A mixed methanogenic culture fed with glucose was perturbed with butyrate and formate to investigate the role of formate in the acetogenesis of butyrate. A free energy analysis suggests that formate rather than H(2) was the interspecies electron carrier for butyrate conversion into acetate for the culture studied.
