Isolation and mass production of Azotobacter species potential useful in agricultural application
Authors

Abstract
Great many papers on this genus have dealt
with its significance in plant nutrition and its contribution to soil
fertility. Because of this and for better clarity, this paper has been divided
into three sections: Azotobacteria and their natural habitat (the soil
and plant); production of growth substances and their effects on the plant; and
possibility of using Azotobacteria in agriculture. As soil bacteria, Azotobacteria
cannot be studied without their natural environment. The main focus of study
was the soil as the natural habitat of these bacteria. A bacterium of the Azotobacteria
genus synthesizes IAA and these growth materials are the primary substances
controlling the enhanced growth. These hormonal substances, which originate
from the rhizosphere or root surface, affect the growth of the closely
associated higher plants. In order to guarantee the high effectiveness of
inoculants and microbiological fertilizers it is necessary to find the
compatible partners, i.e. a particular plant genotype and a particular Azotobacteria
strain that will form a good association.
