Probiotics play a vital role in clinical applications for the treatment of diarrhea, obesity and urinary tract infections. Phytate, an anti-nutrient, chelates essential minerals that are vital for human health. In the past few decades, research reports emphasize extensively on phytate degradation in animals. There is a growing need for finding alternate strategies of phytate utilization in human, as they are unable to produce phytase. At this juncture, probiotics can be utilized for phytase production to combat mineral deficiency in humans. The main focus of this review is on improving phosphate bioavailability by employing two approaches: supplementation of (1) fermented food products that contain probiotics and (2) recombinant phytase producing bacteria. In addition, several factors influencing phytase activity such as bacterial viability, optimal pH, substrate concentration and specificity were also discussed.
