Degradation of phytate in rice bran by local bacteria phytase

Phytate (myo-inositol hexakisphosphates), a phosphorylated derivative of myo-inositol, is widely distributed in plants, particularly in cereals and legumes, such as corn, soybean, wheat bran, rice bran, cotton seeds, rape seeds and soybean with a concentration range between 0.4% to 6.4%. Rice bran,...
