Molecular hydrogen is an important intermediate in the degradation of organic matter by microorganisms in anoxic habitats such as freshwater and marine sediments, wet land soils, and the gastrointestinal tract of animals. In these particular conditions H2 is produced during fermentation of carbohydrates, lipids, nucleic acids, and proteins by anaerobic bacteria and,... 

Under conditions of reduced oxygen (O2) availability, selected species of marine bacteria can use NOs as a terminal acceptor for electrons during metabolism, a process termed N03 respiration or dissimilatory N03 reduction. This process allows microorganisms to utilize organic matter in I0W-O2... 

A major proportion of the organic matter on Earth is plant tissue ( biomass ) and is composed of carbohydrates, principally cellulose. This is the structural support polymer of land plants and the material used since ancient times in the form of cotton and linen textiles, and later as paper. Chitin is a polymer related to cellulose that has skeletal function in arthropods and fungi. Other polymeric carbohydrates constitute the structural support framework for marine plants and the cell walls of microorganisms. The sweet carbohydrate of sugar cane, now termed sucrose, has been a dietary item for at least 10 millennia.
