Abstract

Isolate and identify the phosphate solubilization ability of marine yeast Candida tropicalis and its alternative approach for bio fertilizer. The marine yeast was isolated and subjected to observe phosphate solubilization of yeast by plating in Pikovskaya medium and the characterization of yeast was done by the microbial and biochemical methods. The phosphate solubilization was measured by phosphate molybdenum method. The growth of Sorghum bicolor crop and seed was measured by using phosphate solubilized yeast in the field.

Keywords

Candida tropicalis, phosphate solubilization, biofertilizer, Pikovskaya medium

Conclusion

Phosphorous is an essential macronutrient for plant growth and development. About 95- 99% present in soil insoluble form. Phosphate solubilizing microorganisms can increase soil phosphate solubility and availability. This study was aimed to identify and evaluate phosphate solubilizing yeast, yeast species were positive in phosphate solubilizing ability. Therefore, these species can be candidate and exploited after further evaluation as bio fertilizers. Utilization efficiency of crops for phosphate chemical fertilizer is around 30%, the remaining 70% exist in compound and bound form, such economic considerations and phosphate existence in compound form necessitate for an alternative less expensive and environmentally friendly bio fertilizer improving yield and quality.
