methanogen
Danh từ
Số nhiều: methanogens
This term is used exclusively within scientific and technical registers, specifically in microbiology, ecology, and geochemistry. It describes a specialized group of organisms that occupy a narrow ecological niche where oxygen is absent, making it a key term when discussing anaerobic digestion or the carbon cycle.
Because it refers to a specific biological entity, it is used as a countable noun. Researchers typically refer to a "methanogen" when discussing a single species or strain, and "methanogens" when referring to the group or a population within a sample.
