phytase in releasing phytate phosphorus in the diets for swine and poultry [58]. Two phytases with high activity at low temperature and neutral pH, which are the desirable qualities for its application in aqua feed, have been isolated from Pedobacter nyackensis and Erwinia carotovora [59,60]. A few strains of lactic acid bacteria have also been reported to possess phytate-degrading activity [61]. Sixtyseven phytate-degrading bacteria were isolated from different habitats in the extreme environment of the Tibetan plateau and their diversity was analyzed by PCR-RFLP [62]. Phytase-producing strains (Bacillus cereus, Bacillus subtilis, and Pseudomonas aeruginosa) exhibiting potent probiotic properties have been identified [63]. Phytase-producing bacterial isolates identified as Advenella sp. and Cellulosimicrobium sp. were analyzed for their plant growth-promoting activities such as phosphate solubilization, antifungal activity, and production of siderophore, indole acetic acid, hydrogen cyanide, and ammonia [64]. LppA, a cysteine phytase identified from Legionella pneumophila, the causative agent of Legionnaires’ pneumonia, was proposed to represent a therapeutic target to combat intracellular pathogens [65].
