Abstract
Novel phytases derived from ruminal microorganisms are provided. The phytases are capable of catalyzing the release of inorganic phosphorus from phytic acid. Preferred sources of phytases include Selenomonas, Prevotella, Treponema and Megasphaera. A purified and isolated DNA encoding a phytase of Selenomonas ruminantium JY35 (ATCC 55785) is provided. Recombinant expression vectors containing DNA's encoding the novel phytases and host cells transformed with DNA's encoding the novel phytases are also provided. The novel phytases are useful in a wide range of applications involving the dephosphorylation of phytate, including, among other things, use in animal feed supplements.
