Question

Is Azotobacter aerobic?

Answer 1

Azotobacter:

1. Azotobacter is a genus of bacteria that are generally motile, oval, or spherical in shape, develop thick-walled cysts (with a hard crust), and can create vast amounts of capsular slime.
2. They are aerobic, free-living soil microorganisms that play a crucial part in nature's nitrogen cycle by binding atmospheric nitrogen that plants cannot access and releasing in the form of ammonium ions into the soil (nitrogen fixation).
3. It is used by humans to produce biofertilizers, food additives, and certain biopolymers, in addition to being a model organism for researching diazotrophs. Martinus Beijerinck, a Dutch microbiologist and botanist, discovered and named the first member of the genus, Azotobacter chroococcum, in 1901.
4. Azotobacter species are Gram-negative bacteria that may be found in neutral and alkaline soils, water, and in conjunction with certain plants.
