Considering that birds are unable to hydrolyze efficiently this molecule present in the grain, as they do not produce sufficient amount of endogenous
phytase, the utilization and the digestibility of phytic phosphorus and bounded nutrients are affected [6].

PhytaseWe have previously produced recombinant thermostable
phytase and now we have characterized the cellulase.
Approximately less than one-third of the phosphorus (P) in feedstuffs of plant origin is biologically accessible to poultry [National Research Council (NRC), 1994] because they do not have the digestive enzyme
phytase to hydrolyze the phytate phosphorus (Nelson, McGillivray, Shieh, Wodzinski, & Ware, 1968).

phytase, carbohydrase, protease and lipase) are used in aquaculture feeds to overcome the negative effects of anti-nutritional factors, and to improve the digestion of dietary components and enhance growth of fish [15,16].
One approach, being investigated by ARS and university scientists in Auburn, Alabama, is to spray plant-based feeds with
phytase, a commercially available enzyme that destroys phytic acid and is used with pig and other livestock feeds.
