Abstract
Acid phytase is produced by the aerobic culture of a microorganism in a medium containing sources of carbon and nitrogen and inorganic salts, the available orthophosphate content of the medium being maintained at less than 0.005% by weight (as phosphorus). This concentration is less than the optimum for growth of the organism but results in an enhanced production of the enzyme. The microorganism may be a fungus, e.g. Aspergillus niger, A. oryzae, A. flavus, A. flavipes, A. melleus, A. giganteus, A. parasiticus, A. phoenicis, A. tamarii, A. nidulans, A. repens, A. clavatus, A. terreus, A. saitoi, A. awamori or a species of Rhizopus, Penicillium or Mucor, a yeast, e.g. Hansenula subpelliculosa or Saccharomyces cerevisiae, or a bacterium e.g. Escherichia coli.ALSO:Acid phytase prepared by culture of a micro-organism (see Division C3) is added to corn meal, wheat bran, rice bran, cereal grains, or cottonseed, linseed or soybean meal for animal feeding to render the phytin phosphorus in the feed available to the animal.
