Plausible exploitation of Jatropha de-oiled seed cake for lipase and phytase production and simultaneous detoxification by Candida parapsilosis isolated from poultry garbage.

Jatropha de-oiled seed cake was explored to utilize as a basic nutrient source for Candida parapsilosis, isolated from poultry garbage and selected based on the production of lipase and phytase enzymes under submerged fermentation. At optimized parameters under solid-state fermentation, lipase and phytase activities were recorded as 1056.66±2.92 and 833±2.5U/g of substrate (U/g), respectively. Besides enzyme production, complete elimination of phorbol esters and significant phytate reduction from 6.51±0.01 to 0.43±0.01g/100g of seed cake were noted after 3days incubation. Curcin and trypsin inhibition activity were reduced significantly from 26.33±0.43 to 0.56±0.02mg/100g and 229.33±2.02 to 11.66±0.28U/g, respectively after 5days incubation. Saponins were reduced from 5.56±0.19 to 1.95±0.01g/100g of seed cake after 7days incubation.
