BACKGROUND Phytate is an anti-nutritional factor in plants, which catches the most phosphorus contents and some vital minerals. Therefore, Phytase is added mainly as an additive to the monogastric animals' foods to hydrolyze phytate and increase absorption of phosphorus. OBJECTIVES Y. intermedia phytase is a new phytase with special characteristics such as high specific activity, pH stability...

This study explores the potential application of rice bran (agro waste) to nano-encapsulate phytase, which is a thermally unstable biologically active enzyme. Rice bran was converted to nanofibers (20-50 nm in diameter) using electrospinning. After optimizing the pH, viscosity, voltage and the distance between electrodes for electrospinning, phytase enzyme was encapsulated and the fibers were c...

Aspergillus fumigatus contains a heat-stable phytase of great potential. To determine whether this phytase could be expressed in plants as a functional enzyme, we introduced the phytase gene from A. fumigatus (fphyA) in tobacco (Nicotiana tabacum L. cv. NC89) by Agrobacterium-mediated transformation. Phytase expression was controlled by the cauliflower mosaic virus (CaMV) 35S promoter. Secretio...

Phytases catalyze the release of phosphate from phytic acid. In this study, a phytase producing bacterial strain Shigella sp. CD2 was isolated from the wheat rhizosphere. Phytase production started from the exponential phase of bacterial growth, showing the highest activity during the stationary phase. The enzyme activity was detected in both periplasmic and intracellular fractions. The enzyme ...

background: it has been shown that zinc has an effect on physiological responses in animals and birds. on the other hand, dietary phytase in poultry results in increased availability of zinc. objectives: this study was conducted to investigate the effects of zinc oxide (zno) and escherichia coli-derived 6-phytase supplemented diets on the plasma metabolites and enzyme activities of broiler bree...

Fifty isolates capable of producing phytase were isolated from various soil samples. Out of fifty isolates five isolates showed maximum phytase activity. P6 isolate was selected for further study P6 isolate was biochemically characterized as Pseudomonas spp. The culture conditions were optimized for maximum enzyme production. The best carbon and nitrogen sources for maximum phytase production w...
