Abstract
Exploration of different Azospirillum strains from various crop soils of Srivlliputtur Taluk was analysed. There are three different species of strains were found and analysed with different parameters like their morphology, motility, catalase and biotin content. However, the biology was also been studied which includes the vitamin and carbon utilization of the Azospirillum. In this results showed that there are two different species of Azospirillum were identified in all the soils namely A.lipoferum, and A.brasilense. The morphology, biochemical parameters of these two species of Azospirillum are varied according to the soil in which they are identified. It is concluded that the strains of Azospirillum will help to the plants for better growing by means of utilization of various parameters from the soil to the plants and these strains are used as very efficient biofertilizers in the crop plants from all over the world.
Highlights
Biofertilizer is a wide term which includes a diverse category of bioinoculants such as nitrogen fixers, phosphate solubilizers, phosphate mobilizers and plant growth promoting rhizobacteria
Fifteen Azospirillum strains were isolated from the soil samples collected from different crop plants at various places of Srivilliputtur Taluk, Virudhunagar district
Azospirillum population was least in soil samples collected from bhendi (Table 1)
Summary
Biofertilizer is a wide term which includes a diverse category of bioinoculants such as nitrogen fixers, phosphate solubilizers, phosphate mobilizers and plant growth promoting rhizobacteria. The name lipoferum means fat bearing; brasilense from brasiliensis pertaining to the country of Brazil, South America They explored the high potentiality of Azospirillum as microbial inoculant with tropical grasses and other crop plants. Azospirillum is a gram negative, motile, curved rod of variable size, ranging from 0.5 – 1μm in length, exhibits spirillar movement and polymorphism, containing poly-β- hydroxy butyrate (PHB) granules and fat droplets [4,5] They contain peritrichous flagella and polar flagellum used for swarming [6] It was associated with the root system of plants making use of the nutrients exuded by them. The present study aims to isolate, identify, screen and study the biology of Azospirillum spp from various soils of Srivilliputtur Taluk, Virudhunagar District, Tamil Nadu, India
