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].

We 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).
coli with a monocot expression vector in which phytase gene cassette was cloned.
The negative effects of the lack of availability of phosphorus and other minerals bound by phytic acid can be reduced it by degrading the phytic acid bonds by hydrolysis via the phytase enzyme.
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.
