Estimation of methanogenesis by quantification of coenzyme F430 in marine sediments
methane hydrate methanogens function-specific compound analysis marine sedimen
2017/4/10
Coenzyme F430 is the hydrocorphinoid nickel complex which acts as active site in methyl-coenzyme M reductase
(MCR). The MCR-F430 complex catalyzes the last step of methanogenesis: reduction of methyl...
Microbial Community Composition and the Effects of Trace Elements on Methanogenesis Associated with Deep Subsurface Coal
Biological sciences Coalbed methane Coal biodegradation Methanogenesis Trace elements
2015/1/28
Biogenic coalbed methane (CBM), an end product of anaerobic coal biodegradation, is a natural gas. It is generated and trapped in large quantities in deep, unmineable coalbeds. This dissertation descr...
Changes in Microbial Diversity, Methanogenesis and Fermentation Characteristics in the Rumen in Response to Medicinal Plant Extracts
Real-time PCR Relative Quantification Ruminal Methanogenesis
2016/5/12
This study evaluated the in vitro effect of medicinal plant extracts on ruminal methanogenesis, four different groups of methanogens and ruminal fermentation characteristics. A fistulated Holstein cow...
