Hi there,
We know that nitrogen is one of the primary nutrients critical for the survival of all living organisms. It is a necessary component of many biomolecules, including proteins, and DNA. All organisms on Earth require nitrogen to survive. Does that mean that all microbes can absorb or assimilate nitrogen from the environment (These include any form of organic or inorganic nitrogen)? If not, where does nitrogen come from in microbes? Thank you very much!
Best wishes,
Quan
Though, largest pool of freely accessible N2 is atm. N2 but only free living or symbiotic N2 fixer can make use of it. Most of the m. O rely on NH4 and NO3 - N for their growth. The availability of these substrates depend on diverse N2 transforming reactions carried out by nitrifiers and denitrifiers and similar classes inadequate. Microbial N- transforming net works both attenuate and exacerbate human induced global change. They produce and consume powerful green house gas nitrous oxide, lead to eutrophication of aquatic system and at the same time remove nitrogen from water.
