Abstract:
:The maintenance energy coefficient of Desulfovibrio vulgaris was studied by using a chemostat, with Methanosarcina barkeri or sulfate as the electron acceptor; lithium lactate or sodium pyruvate served as the electron donor. The experiments showed that the growth energetics of D. vulgaris or M. barkeri were greatly affected by maintenance energy coefficients. When D. vulgaris grew on lactate or pyruvate medium with sulfate, these coefficients reached 4.40 and 2.80 mM g-1 h-1, respectively; on lactate medium in the presence of M. barkeri the same coefficient reached a value of 2.90 mM g-1 h-1. Results also showed that the increase of the value of the maintenance energy coefficient corresponded to a decrease of the biomass produced. D. vulgaris maximal growth yield values calculated by use of the Pirt equation were slightly higher with M. barkeri (maximal growth yield, 10 g/mol) than with sulfate (maximal growth yield, 7.5 g/mol). This finding could be interpreted by reference to the ATP-generating reactions involved in D. vulgaris growth in the presence of sulfate or M. barkeri.
