Methane is an important greenhouse gas and microbes in the environment play major roles
in both global methane emissions and terrestrial sinks. However, a full mechanistic …

Methanogens are a unique group of strictly anaerobic archaea that are more metabolically
diverse than previously thought. Traditionally, it was thought that methanogens could only …

Methanogenesis is the primary biogenic source of methane in the atmosphere and a key
contributor to climate change. The long-standing dogma that methanogenesis originated …

Carbon monoxide dehydrogenase/acetyl-CoA synthase (CODH/ACS) is a five-subunit
enzyme complex responsible for the carbonyl branch of the Wood–Ljungdahl (WL) pathway …

The atmospheric concentration of methane (CH4), a major greenhouse gas, is mainly
controlled by the activities of methane-producing (methanogens) and methane-consuming …

The prevailing paradigm in aquatic science is that microbial methanogenesis happens
primarily in anoxic environments. Here, we used multiple complementary approaches to …

Resource recovery and prevention of environmental pollution are key goals for sustainable
development. It is widely reported that agro-industrial activities are responsible for the …

Methylmercury (MeHg) production was compared among nine cultured methanogenic
archaea that contain hgcAB, a gene pair that codes for mercury (Hg) methylation. The …

Oil sands tailings ponds receive and store the solid and liquid waste from bitumen extraction
and are managed to promote solids densification and water recycling. The ponds are highly …

Anaerobic digestion of high-salinity wastewaters often results in process inhibition due to the
susceptibility of the methanogenic archaea. The ability of the microbial community to deal …
