Yeast Acid Phosphatases and Phytases: Production, Characterization and Commercial Prospects

A novel phytase characterized by thermostability and high pH tolerance from rice phyllosphere isolated Bacillus subtilis B.S.46

“…Numerous researchers have shown that microbial phytases are more promising for the commercial production of phytase [7] , [8] , [9] . Although several strains of bacteria [10] , yeasts [11] , and fungi [9] have been isolated and studied for phytase production, currently commercial scale feed phytases are mainly derived from Aspergillus niger (3-phytase), Peniophora lycii and Escherichia coli (6-phytase) [7] , [12] . However, according to strict substrate specificity, higher heat stability, wide pH profile, and resistant to proteolysis, Bacillus phytases are potential alternatives to fungal ones [8] , [13] , [14] .…”
