Phytate, the major source of phosphorus in seeds, exists as a complex with different metal ions. Alkaline phytases are known to dephosphorylate phytate complexed with calcium ions in contrast to acid phytases that act only on phytic acid. A recombinant alkaline phytase from Bacillus sp. MD2 has been purified and characterized with respect to the effect of divalent metal ions on the enzyme activ...
Abstract We aimed to investigate phosphorus (P) mobilization by different plant species from organic and inorganic sources in relation P mechanisms. Knowledge about is important for producing crops on other than phosphate rock-derived fertilizers. conducted a greenhouse experiment with four (maize, soy, lupin, mustard) three (FePO 4 , phytate, struvite). determined pH phosphomonoesterase activi...
An experiment was conducted to evaluate the effects of one alpha-hydroxycholecalciferol (1α-OH D3) on growth performance, tibia quality, and skin and meat color in broilers fed calcium (Ca)- and phosphorus (P)-deficient corn-soybean meal diets. A total of 288 male Ross broilers, at 21 days of age, were randomly assigned to three treatments with eight cages per treatment. Three levels of 1α-OH D...
We have recently expressed a new phytase enzyme in a yeast system. Three experiments with a total of 140 weanling crossbred pigs were conducted to examine the efficacy of this enzyme in improving the bioavailability of phytate-P in corn-soybean meal diets to young pigs. Experiment 1 compared the efficacy of this new phytase with a commercially available phytase (Natuphos, BASF) for 4 wk at an i...
Phytases are hydrolytic enzymes that initiate the release of phosphate from phytate In recent years the application of the phytase enzyme have been studied intensively. Phytase enzymes have a wide distribution in plants, microorganisms, and in some animal tissues. Many strategies have been developed for improving phosphate and mineral availability in feed. However in recent years, expression of...
