Desulfovibrio vulgaris (Marburg) and Methanobrevibacter arboriphilus (AZ) are anaerobic sewage sludge bacteria which grow on H2 plus sulfate and H2 plus CO2 as sole energy sources, respectively. Their apparent Ks values for H2 were determined and found to be approximately 1 μM for the sulfate reducing bacterium and 6 μM for the methanogenic bacterium. In mixed cell suspensions of the two bacteria (adjusted to equal Vmax) the rate of H2 consumption by D. vulgaris was five times that of M… Expand

Kinetic mechanism for the ability of sulfate reducers to out-compete methanogens for acetate
Methanosarcina barkeri and Desulfobacter postgatei are ubiquitous anaerobic bacteria which grow on acetate or acetate plus sulfate, respectively, as sole energy sources. Their apparent Ks values forExpand
Why do sulfate-reducing bacteria outcompete methanogenic bacteria for substrates?
TLDR
Difference in substrate affinity can account for the inhibition of methanogenesis from H2 and CO2 in sulfate-rich ecosystems (mainly saltwater marshes), where the H2 concentration is well below 5 μM. Expand
Competition between sulfate-reducing and methanogenic bacteria for H2 under resting and growing conditions
TLDR
Calculated μmax and Vmax/Km values for the methanogens and sulfidogens studied predict that the latter bacterial group will process more H2 whether these organisms are in a growing or resting state, when the H2 concentration is in the first-order region. Expand
Competition for ethanol between sulfate-reducing and fermenting bacteria
TLDR
In competition experiments with ethanollimited chemostat cultures the sulfate-reducing bacteria Desulfobulbus propionicus and Desulfovibrio vulgaris outcompeted Pelob bacteria at dilution rates below their maximum specific growth rates. Expand
Physiological basis for sulfate-dependent hydrogen competition between sulfidogens and methanogens
Desulfovibrio vulgaris strain Madison outcompetedMethanobacterium strain ivanov for hydrogen when sulfate was in excess because of higher cell yield and growth rate and a greater affinity forExpand
The capacity of hydrogenotrophic anaerobic bacteria to compete for traces of hydrogen depends on the redox potential of the terminal electron acceptor

Dependence of the specific growth rate of methanogenic mutualistic cocultures on the methanogen
TLDR
It is demonstrated experimentally that with methanogens known to have similar Ks (H2) values, the specific growth rates of methanogenic mutualistic cocultures are dependent upon the maximum specific growth rate of the methanogen. Expand
Kinetic characterization of Methanobacterium bryantii M.o.H.
TLDR
This self-consistent set of parameters indicates that, when H2 is not limiting, M.H. bryantii is a slow grower compared to other H2-oxidizing methanogens and sulfate reducers, and this is mainly due to its low true Y, not a low qmax. Expand
Effect on methane digestion of decreased H2 partial pressure by means of phototrophic or sulfate-reducing bacteria grown in an auxiliary reactor
SummaryH2 is a central metabolite in the process of methane digestion. In this study, the partial pressure of H2 was decreased by sparging the gas phase of the digester through an auxiliary reactorExpand
Interspecific hydrogen transfer during methanol degradation by Sporomusa acidovorans and hydrogenophilic anaerobes
TLDR
In the presence of active hydrogenophilic sulfate-reducing bacteria, the homoacetogenic bacterium Sporomusa acidovorans did not produce acetate during methanol degradation, and the results suggested that H2-production and H1-consumption were involved during anaerobic methnol degradation by S. acidov orans.

Growth of Desulfovibrio in Lactate or Ethanol Media Low in Sulfate in Association with H2-Utilizing Methanogenic Bacteria
TLDR
The results with known mixtures of bacteria suggest that hydrogenase-forming, sulfate-reducing bacteria could be active in some methanogenic ecosystems that are low in sulfate, and it is suggested that lack of availability of H(2) for growth of methanogens is a major factor in suppression of meetinghanogenesis by sulfate in natural ecosystems.

Hydrogen as a substrate for methanogenesis and sulphate reduction in anaerobic saltmarsh sediment
TLDR
The removal of inhibition of methanogenesis by the use of fluorolactate to suppress sulphate reduction or by the provision of hydrogen indicates competitive inhibition of meethanogens by sulphate reducers utilizing transferred hydrogen. Expand

Effect of inorganic sulfide on the growth and metabolism of Methanosarcina barkeri strain DM
TLDR
The data suggested that at elevated sulfide levels (12.5 mM) the decrease in YCH4 might be a result of an increase in the relative energy needed for maintnenace and of uncoupling of growth from energy production. Expand

TLDR
H(2) produced by the Desulfovibrio species during growth with lactate inhibited acetate degradation by M. barkeri, and the ultimate rate of acetate utilization for methanogenesis was greater for those cocultures receiving the highest levels of lactate. Expand
Kinetic Parameters of the Conversion of Methane Precursors to Methane in a Hypereutrophic Lake Sediment
TLDR
Kinetic experiments using [2-C]acetate and sediments collected in the summer indicated that acetate was being converted to methane at or near the maximal rate, and indicate that methane may not be the only fate of hydrogen in the sediment. Expand
