Answer 1

Answer:

bacillus , azatobacter

Answer 2

The non-symbiotic bacteria which fix nitrogen live in the soil independently are Cyanobacteria, Anabaena, Nostoc, etc.

• Nitrogen fixation in soil takes place by prokaryotic organisms.
• Prokaryotes that fix the nitrogen fixation are of various types.  The one who fixes nitrogen by the symbiotic way and the ones who fix it by the non-symbiotic way.
• The non-symbiotic are free-living that is they live independently and fix nitrogen mostly in leguminous plants.
• Then fix nitrogen by nodule formation in cortical cells.

• Here are a few examples, Cyanobacteria (commonly called Blue-green algae), Anabaena, Nostoc.

• Also, some genera like Beijerinckia, Clostridium, Azotobacter are examples of non-symbiotic free-living nitrogen-fixing bacteria.
