Question

example of bacterium which helps in biological nitrogen fixation?

Answer 1

Two types of bacteria do this job: non-symbiotic bacteria in the soil and symbiotic bacteria that live in the roots of plants. Bacteria in the genera Clostridium and Azotobacter are non-symbiotic nitrogen-fixing bacteria, while those in the genus Rhizobiumare symbiotic bacteria.

Answer 2

Hello dear,

# Nitrogen fixing bacteria -

1. Rhizobium
2. Cyanobacteria
3. Anabaena
4. Azotobacter
5. Clostridium
6. Nostoc

◆ Rhizobium -

• Rhizobia is a symbiotic bacteria that resides in this nodules of leguminous plants.
• This Rhizobia carry out the function of nitrogen fixation in atmosphere.
• Nitrogen gas is converted into ammonia during this process of nitrogen fixation.
• Rhizobium is used as biofertilizer because of this property.

Thanks dear. Hope this helps you...
