In anaerobic conditions. Carbon is emitted in the form of methane. By the methanogen bacteria, methane is converted to carbon dioxide. By methylotroph bacteria as methylomonas.
Best in the State, there are no oxygen. Carbon is released as methane gas by Methanogen bacteria are a group of gases, methane is converted to carbon dioxide by Methylotroph Methylomonas group of bacteria.
The State does not have a carbon oxygen is released in the form of methane gas by working groups of bacteria Methanogen methane gas will be replaced with a carbon dioxide emissions by bacteria such as Methylomonas Methylotroph group
