Estimation of methanogen biomass via quantitation of coenzyme M
Dwayne A. Elias, Lee R. Krumholz, Ralph S. Tanner, Joseph M. Suflita
1999, Applied and Environmental Microbiology (65) 5541-5545
Determination of the role of methanogenic bacteria in an anaerobic ecosystem often requires quantitation of the organisms. Because of the extreme oxygen sensitivity of these organisms and the inherent limitations of cultural techniques, an accurate biomass value is very difficult to obtain. We standardized a simple method for estimating methanogen...
