Abstract
Azotobacter is a well-known nonsymbiotic nitrogen fixer. Although Azotobacter was described in 1901, the organism is attracting microbiologist attention for its interesting potential applications. India is recognized as hot spot of biodiversity, and this may offer an opportunity to screen various strains of Azotobacter from different habitat with various novel potential. Agriculture is one of the major sectors of the Indian economy, and hence the isolation of new and potentially beneficial organisms for various crops is a current priority in developing countries like India due to the increasing prices of petroleum-based fertilizers. The present chapter describes the simple morphological and biochemical characteristics of different Azotobacter sp., which is useful to screen and identify potent Azotobacter sp. in minimal laboratories.
