Energy + end products
Biogeochemical cyclingDescribes the transport and transformation of materials caused by biochemical activities in atmosphere, soil and marine environments.Occurs Globaly and in micro habitats
Transformations * Physical : Leaching, precipitation, evaporation and immobilization* Chemical:: Biosynthesis, biodegradation, oxidation/reduction
Microorganisms:
AssimilationBiosynthesis
BiotransformationExcretion
Methane and methanogenesis
Methanogenic bacteria 4H2 + CO2 CH4 + 2H20
Other sources (electron donors) for methan production:
CH3OH - methanol
HCOO- formate
CH3SH methyl mercaptan
CH3COO- acetate
