Abstract
The present invention relates to isolated polypeptides having phytase activity, the corresponding cloned DNA sequences, a process for preparing such polypeptides, and the use thereof for a number of industrial applications. In particular, the invention relates to phytases derived from the phyllum Basidiomycota, phytases of certain consensus sequences and fungal 6-phytases.
