Biotechnological phytase preparations are commercially available and are currently used in animal feeding.However, thermostability constraints, low yields, and the high cost of the enzyme have limited its use. This study represents anew perspective for the food enzyme market. The research screened thermostable yeast strains for their ability to producephytase. The screening was carried out with a gradual increase in temperature (30-48oC). Sixteen strains (1 strain identified asSaccharomyces cerevisiae) maintained the ability to produce phytase at 48oC and their phytase activity was confirmed using 2phytase assay methodologies. The yeast strains tested in this study seem to be potential efficient producers of phytase,indicating a possible new source of thermostable phytase of commercial interest, particularly that from S. cerevisiae.
