Releasing phosphorus from phytate with a phytase
enzyme reduces the environmental load and also reduces the cost of feed, as other sources of phosphorus are then required at lower levels.
The reasons for the aforementioned inconsistencies of phytase
effects on digestibility of nutrients other than P are not well understood.
The other part was sealed, stored at 4[degrees]C, and analysed for soil phytase
activity and microbial biomass C (MB-C) and MB-P within 48 h.
Determination of phosphate concentration was done following the method for phytase
assay described by Engelen et al.
Diets 2 to 5 were supplemented with 150, 300, 450 and 600 FTU/Kg phytase
A very small amount of phytase
activity is present in the small intestine, (16) but most phytate appears to transit the digestive tract relatively intact, (17) with bacterial fermentation occurring largely in the large intestine.
To take care of this, researchers took a gene responsible for the creation of phytase
NSP-enzymes degrade the non-starch polysaccharide fraction in feed, whereas phytase
improves the use of the phytic acid present in most plant-derived feedstuffs.
corn was also locally developed by China's Academy of Agricultural Science and Nasdaq-listed Origin Agritech Ltd, which has seen its share price double since shareholders were notified of the approval on Saturday.
Verenium Corporation (San Diego, CA) has patented a purified recombinant phytase
enzyme derived from Escherichia coli B.
High moisture content and relative humidity also stimulate phytase
and pectin methyl esterase activity (PME) .
Effect of phytase
supplementation on the performance of broilers grown to market weights.
