Journal ArticleDOI
Carbon and Electron Flow in Mud and Sandflat Intertidal Sediments at Delaware Inlet, Nelson, New Zealand
TL;DR: The results suggested that although methanogenesis was inhibited by sulfate (presumably through the activity of sulfate-reducing bacteria), it was not always limited by sulfATE reduction.
Journal ArticleDOI
Production and regulation of cellulase by two strains of the rumen anaerobic fungus Neocallimastix frontalis.
TL;DR: Exoglucanase, measured with alkali-treated Sigmacell or Avicel, gave low levels of activity in the culture fluid and did not appear to be associated with the fungal rhizoid, as treatment with various solubilizing agents failed to give increased activity.
Journal ArticleDOI
Fermentation of Cellulose to Methane and Carbon Dioxide by a Rumen Anaerobic Fungus in a Triculture with Methanobrevibacter sp. Strain RA1 and Methanosarcina barkeri.
TL;DR: The effect of methanogens is interpreted as a shift in the flow of electrons away from the formation of electron sink products lactate and ethanol to methane via hydrogen, favoring an increase in acetate, which is in turn converted to methane and carbon dioxide by M. barkeri.
Journal ArticleDOI
Effect of inorganic sulfide on the growth and metabolism of Methanosarcina barkeri strain DM.
TL;DR: 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.
Journal ArticleDOI
Changes in proportions of acetate and carbon dioxide used as methane precursors during the anaerobic digestion of bovine waste
TL;DR: This article corrects the article on p. 651 in vol.
