In Vitro Characterization of a Novel Consensus Bacterial 6-Phytase and One of its Variants

Current Biochemical Engineering, 2020
Background:: Microbial phytases are added to animal feed to hydrolyze phytic acid (myoinositol hexakisphosphate, IP6) and phytate (salt of phytic acid) increasing phosphorus bioavailability. Novel phytases with enhanced bio-efficacy are being developed.

Evaluation of Commercial 6-Phytases on Growth Performance, Bone Mineral Content, and Feed Digestibility of Broiler Chicks

The Journal of Poultry Science, 2022
We evaluated the effects of 6-phytases on the growth performance of broilers (UK Chunky) under the recommended supplier-application dosage of each phytase. A nutritionally sufficient standard diet was administered as the base diets in the positive control feed.

Comparison of mucosal phosphatase activity, phytate degradation, and nutrient digestibility in 3-week-old turkeys and broilers at different dietary levels of phosphorus and phytase

Poultry Science, 2023
: A comparison between 3-wk-old female turkeys (B.U.T. 6) and broilers (Ross 308) was performed to study the effects of species, dietary P, Ca, and phytase levels on gut mucosal phosphatase activity, myo-inositol hexakisphosphate (InsP6) degradation ...

Inositol and gradient phytase supplementation in broiler diets during a 6-week production period: 2. Effects on phytate degradation and inositol liberation in gizzard and ileal digesta contents1

Poultry Science, 2021
An experiment was conducted to evaluate effects of dietary phytase and inositol supplementation on phytate degradation in gizzard and ileal digesta contents of broilers from 1 to 43 d of age.

Ileal and total tract digestibility of energy and nutrients in pig diets supplemented with a novel consensus bacterial 6-phytase variant. [PDF]

J Anim Sci, 2022
AbstractAn experiment was conducted to test the hypothesis that increasing levels of a novel phytase increases the apparent ileal digestibility (AID) and apparent total tract digestibility (ATTD) of nutrients in diets fed to young pigs. A negative control (NC) diet based on corn, soybean meal, and canola meal that contained approximately 0.83% phytate (

Assessment of a bacterial 6-phytase in the diets of broiler chickens

Poultry Science, 2013
Two 21-d broiler experiments were conducted to assess the efficacy of a bacterial 6-phytase expressed in Aspergillus oryzae on growth performance, nutrient utilization, and intestinal molecular markers. Two hundred forty birds in 5 treatments (experiment 1) or 256 birds in 4 treatments (experiment 2) were used.

EFFECT OF USING DIFFERENT SOURCES OF PHYTASE ON SOME PRODUCTIVE PERFORMANCE OF BROILER CHICKS. [PDF]

Minia Journal of Agricultural Research and Development, 2019
A total number of 240 unsexed, one-day old Arbor Acres broiler chicks were randomly distributed into 6 experimental groups of 40 birds each. Each group contained four replicates of 10 birds each.

Enhanced Farrowing Efficiency and Sow Performance with <i>Escherichia coli</i>-Derived 6-Phytase Supplementation During Late Gestation and Lactation. [PDF]

Animals (Basel)
Phytase releases phosphorus from phytate and may confer extra-phosphoric benefits in sows. We tested whether Escherichia coli-derived 6-phytase during late gestation and lactation improves sow and litter outcomes. In a randomized complete block trial, 186 TN70 sows received a phytase-free positive control (adequate Ca and available P) or Ca- and P ...

Degradation of Phytate by the 6-Phytase from Hafnia alvei: A Combined Structural and Solution Study

PLoS ONE, 2013
Phytases hydrolyse phytate (myo-inositol hexakisphosphate), the principal form of phosphate stored in plant seeds to produce phosphate and lower phosphorylated myo-inositols. They are used extensively in the feed industry, and have been characterised biochemically and structurally with a number of structures in the PDB.
