WebAzotobacter strains are natural bioremediator and can tolerate different climatic conditions in the soil ecosystem. It is evident from this study that Azotobacter strains are potential bio-agents for agriculture and maintaining of ecological imbalance in the environment. Azotobacter respires aerobically, receiving energy from redox reactions, using organic compounds as electron donors, and can use a variety of carbohydrates, alcohols, and salts of organic acids as sources of carbon. Azotobacter can fix at least 10 μg of nitrogen per gram of glucose consumed.
