Spore forming bacterial biofertilizer for phosphate solublization and bio-control agen

Spore forming bacteria are resistance to heat, drying, radiation, chemicals, disinfectants and antibiotics. So, the spore forming bacteria are used as a biofertilizer in agricultural purposes. Microbial solubilization of hardly soluble mineral phosphate in soil is an important process. Phosphorus involved in photosynthesis, respiration, energy storage and transfer, cell division and enlargement etc. Ten soil samples were collected from different rhizosphere regions and spreaded on Pikovaskaya’s agar medium and PDA for isolation of Phosphate solubilising bacteria (PSB) and pathogen (Fusarium). The isolated PSB of Bacillus Species was taken for further studies such as micro morphological and cultural characteristics and antagonistic activity against Fusarium. The strain improvement was carried out on Tricalcium Phosphate (TCP) agar, different temperature, pH, UV treatment and antibiotic sensitivity test. The field soil sample was analyzed and pot culture method was carried out. The spore forming Bacillus strain is resistant to various environmental factors. It improves the crop production and controls the plant pathogen in groundnut.
