Two names of a bacterium facultative anaerobic bacteria are also called facultative aerobic bacteria. This microorganism has wide adaptability and can grow in aerobic or anaerobic environment. Generally, aerobic growth is dominant, and respiratory productivity depends on aerobic growth; It has both anaerobic growth ability and anaerobic fermentation or anaerobic respiration ability. Such as Escherichia coli, Enterobacter aerogenes, members of Enterobacteriaceae, Bacillus licheniformis, Saccharomyces cerevisiae, etc.

Also known as aerobic bacteria and aerobic microorganisms. Growth and reproduction in aerobic environment, oxidation of organic or inorganic substances, aerobic respiration with molecular oxygen as the final electron acceptor. Include most bacteria, actinomycetes and fungi.

The function of stable and effective aquarium biochemical filtration system is to remove NH4, NH3, NO3 and NO2 from water. The whole removal process is generally called nitrogen cycle. The first explanation: refers to bacteria whose main energy source is ammonia or nitrite, and whose main carbon source is CO2. Nitrifying bacteria play an important role in nitrogen cycle. It can convert nitrite into nitrate, which can be used by aquatic plants and algae to improve water quality. & ltbr/>； Another explanation is that. Refers to a bacterium that can oxidize inorganic nitrides and obtain energy from them, thus synthesizing carbon dioxide into organic matter. I think this explanation is relatively clear. Look, everybody.

Denitrifying bacteria (photosynthetic bacteria are also anaerobic bacteria)
