Microbial mediated processes in the nitrogen cycle

Nitrogen fixation Cyanobacteria live everywhere in the aquatic environment Nitrogen fixing bacteria in plant root nodules Microbes fix nitrogen gas into ammonia that is incorporated into plant tissue

Ammonification (Mineralization) Refers to the breakdown of organic matter in order to release the organically bound nitrogen as inorganic (mineral) nitrogen in the form of ammonia Decomposition is the biological process that allows for the process

Nitrifying bacteria (Nitrosomonas and Nitrobacter)

Occurs in oxygen poor or anaerobic environments usually deep in the soil or in muddy sediments

NO 3 - NO 3 - → NO 2 - → NO → N 2 O → N 2 gasNO 2 -NON 2 ON 2 The complete denitrification process can be expressed as a redox reaction 2NO e H + → N 2 + 6H 2 O

Mangrove swamps are areas where denitrification happens

Ecosystems and the Gaia Hypothesis

Ecosystem defined: a community of organisms and it’s corresponding abiotic environment through which matter cycles and energy flows Wide variation in ecosystems Boarders can be well defined or vague Can be natural or artificial, managed or wild Wide range in scale Common to all ecosystems: energy flow and cycling of matter

Gaia Hypothesis(es) Life has greatly affected the planetary environment This alteration has allowed life to persist The Earth is a “super-organism” - Life controls the environment in a fashion that is equivalent to the way an organism controls its various systems Evolution?
