STRUCTURE-FUNCTION STUDIES OF MULTIPLE INOSITOL POLYPHOSPHATE PHOSPHATASES FROM GUT COMMENSAL BACTERIA
… storage form of phosphorous in animal feeds. Phytases are enzymes (myo-inositol hexakisphosphate phosphohydrolases) that break down InsP6 by hydrolysis to release inorganic phosphate. Non-ruminant animals do not produce phytases needed to digest dietary InsP6, instead relying on enzymes …

An in vitro assessment of the effects of feed-grade trace minerals on commercial phytase activity
Exogenous phytases have the capacity to increase the nutritional value of animal feeds through the hydrolysis of phytate-bound phosphorus. Inorganic trace minerals (ITM) routinely added to feed can negatively impact phytase activity. Recent research has shown that replacement of ITMs with organic …

Evaluation of Particle Size Differences, Calcium Sources, and Phytases on Ph and Calcium and Phosphorus Solubility in an in Vitro Simulation of Broiler Digestion
… was to evaluate various Ca sources and microbial phytases using an in vitro assay to simulate broiler digestion. The trial measured total Ca and P, soluble Ca and P, and pH. It involved limestone, dicalcium phosphate, highly soluble Ca (HSC), whey, and a control with no added Ca. Each diet was …

The Interactive Effects of Phosporus and Calcium on Phosphorus Requirement, Utilization, and Phytase Efficacy in Poultry
… relative bioavailability of 2 Escherichia coli phytases. Retained P was higher for broilers fed Finase, which was more bioavailable than Optiphos. One experiment was conducted to investigate the influence of Ca level on the efficacy of phytase. Calcium level did not influence phytase efficacy. …

Efficacy of an Escherichia Coli Phytase for Improving Mineral Utilization in Pigs and Chickens
… values of approximately 0.04% for the other two phytases, relative to monobasic potassium phosphate. In young pigs, 400 FTU/kg of EcoPhos(TM) released 0.11% P, compared to P-release values of 0.08 and 0.04% for NatuphosRTM and Ronozyme RTM, respectively. EcoPhos(TM) (500 FTU/kg) also released …

Functional and community investigation of nodule endophytes for the selection of phosphate solubilizing rhizobial inoculants for clover : A thesis submitted in partial fulfilment of the requirements for the degree of Doctor of Philosophy at Lincoln University
… These bacteria can also release organic acids, phytases and phosphatases to make P soluble and plant available. The goal of this thesis was to understand the potential of P solubilizing rhizobia (PSR) to perform dual functions of P solubilization (PS) and N fixation and determine the magnitude …

The interaction of dietary phosphorus and exogenous phytase concentrations on nutrient metabolism of beef cattle
… The microbial population in the rumen produces phytases; however, passage rate, Ca-complexes formed with phytate, and processing of dietary ingredients can reduce ruminal phytase activity (Konishi et al., 1999; Park et al., 1999; Kincaid et al., 2005). Limited data exists on the addition of …
