title: Production and Consumption of H(2) during Growth of Methanosarcina spp. on Acetate.
abstract: Methanosarcina sp. strain TM-1 and Methanosarcina acetivorans produced and consumed H(2) to maintain H(2) partial pressures of 16 to 92 Pa in closed cultures during growth on acetate. Strain TM-1 produced H(2) continuously when H(2) was continuously removed from the culture. The potential physiological significance of H(2) in acetate metabolism to methane is discussed.
