Rhizobium
1. Nitrogen fixing bacteria
2. Ammonification bacteria
3. Denitrifying bacteria
4. Nitrifying bacteria
Denitrifying bacteria
1. Can induce root nodules on many plant species
2. Can fix nitrogen in the free – living state
3. Like Rhizobium, it usually infacts its host plant proliferation in the host’s cortex
4. Forms specialized vesicles, in which the nitrogen ase is protected from oxygen by a chemical barrier involving triterpene hopanoids

Protein
1. Transfer genes from one plant to another
2. Decompose variety of organic compounds
