Optimisation of Parameters for Fermentation Conditions of Phosphate Solubilising Bacteria

Sonia Sethi,Saksham Gupta

The microorganisms play a vital role in fertility of soil and hence favors’ large group of plants. In present study we have successfully isolated certain Gram negative bacteria from soil and access their ability in phosphate solubilization. Effects of temperature, pH and different carbon sources, on phosphate solubilization, by these isolates were also determined. High temperature 40 °C, pH 6, Dextrose as carbon source, Yeast as Nitrogen source and Soyacake as waste source were found to be best for phosphate solubilization by most of the isolates. Among all isolates Bacillus sp followed by Pseudomonas sp was found to be the best phosphate solubilizers. Present study highlights the importance of these plants growth promoting bacteria and their uses for agriculture purposes.
