Physical and chemical mutagens improved Sporotrichum thermophile : strain ST20 for enhanced Phytase activity

Abstract EN

Phosphorous is an essential micronutrient of plants and involved in critical biological functions.

In nature, phosphorous is mostly present in immobilized inorganic mineral and in the fixed organic form including phytic acid and phosphoesteric compounds.

However, the bioavailability of bound phosphorous could be enhanced by the use of phosphate solubilizing microorganisms such as bacteria and fungi.

The phytases are widespread in an environment and have been isolated from different sources comprising bacteria and fungi.

Methodology In current studies, we show the successful use of gamma rays and EMS (Ethyl Methane Sulphonate) mutagenesis for enhanced activity of phytases in a fungal strain Sporotrichum thermophile.
