Definition

noun

An aerobic rod shape soil-dwelling organism involved in synthesizing nitrogen aerobically which is valuable in measuring health and nutrients of the soil.

Supplement

Azotobacter vinelandii has a size of at least 2 microns in diameter rods and can live singly, in clumps and in chains which may or may not have a whip-like structure flagella used for locomotion. Its resting stage spends in a thick-walled cyst to prevent and protect from uncontrolled harsh environment.

Azotobacter vinelandii has the capability in synthesizing molybdenum-containing nitrogenase enzyme that characterized most of the diazotrophs and two alternative nitrogenases that carry out the chemistry of nitrogen reduction at sites. Shows a great deal of interest in the scientific research due to its unique mode of metabolism wherein it able to fix nitrogen aerobically.

Azotobacter vinelandii is capable of generating a protein that protects the nitrogenase from sudden oxygen-provoked stress and the ability to synthesize three nitrogenases. It has a significant role in every ecosystem by creating nitrogen that is accessible to all organisms that turns into ammonia through the mechanism of nitrogen fixation which eventually turned into proteins needed in agriculture in related to fertilization and crop rotation.
