Nitrogen fixing heterotrophic bacteria

Denitrification The conversion of fixed nitrogen, typically nitrate, into N2 gas. This is achieved by heterotrophic bacteria that use nitrate as an electron acceptor under suboxic and anoxic conditions. [Pg.872]

The sequence of nitrogen fixation and nitrification is a source of fixed nitrogen and a sink of dissolved oxygen in the ocean. Aerobic respiration of organic material by heterotrophic bacteria also consumes oxygen and releases nitrogen to the dissolved inorganic pool the... [Pg.1539]

Under very low oxygen conditions, denitrification, resulting from the anaerobic reduction of nitrate by heterotrophic bacteria, consumes fixed nitrogen in the form of nitrate, ultimately regenerating N2 gas (Froelich et al, 1979). [Pg.1539]

The heterotrophic soil bacteria include nitrogen-fixing bacteria and the denitrifying bacteria that will be discussed later. [Pg.701]
