To date, there are very limited reports on sequence analysis and structure-based molecular modeling of phosphatases produced by probiotic bacteria. Therefore, a novel protein tyrosine-like phosphatase was characterized from L. helveticus 2126 in this study.

The application of exogenous phytases in poultry feed has served as a solution to this problem. However, they are linked to certain limitations which include thermal instability during prolonged feed processing.

The selected bacteria were viable in the intestinal lumen and produced extracellular phytase at optimal phytate concentration of 6.25 mM when compared to 3.

However, recent use of probiotic Bifidobacterium, Enterococcus, and Lactobacillus spp. has been plagued by certain disadvantages such as complex growth requirements, high maintenance cost, susceptibility to the gastrointestinal environment, pathogenic gene transfer, non-standardized dosage, cell lysis at extreme acidic pH, widespread antibiotic resistance, and lower bacterial viability due to the lack of spore formation.
