【 摘 要 】

Phytate, the major storage form of phosphorus in plant seeds, can form insoluble complexes with minerals such as iron, zinc and calcium thus reducing their bioavailability. Phytase enzymes are often used to upgrade the nutritional quality of phytate-rich foods and feeds such as grains. The phytate-degrading activity of 43 lactic acid bacteria including isolates from commercial probiotic preparations, dairy products and type strains were measured. The phytate-degrading activity of bifidobacteria and lactobacillus isolates from pharmaceutical probiotics, dairy products and type strains were determined. The enzyme activity of probotic bacteria ranged between 1.1-5.4 mU and was strain not species specific. Phytase activity may thus be a useful additional attribute of probiotics to be used as food supplements.
