132 microorganisms, isolates from soil and decayed fruits, were tested for phytase production. All isolates intensively producing active extracellular phytase were of fungal origin. The most active fungal isolates with phytase activity were identified as Aspergillus niger. At the end of the growth phase, the extracellular phytase activity produced by A.

Advances in immobilization of phytases and their application
Bioresource Technology, 2023The review describes the advances in the phytase immobilization for the past decade and their biotechnological applications. Different approaches for phytase immobilization are described including the process using organic and inorganic matrices and microbial cells, as well as nanostructures of various nature.

Phytases increase utilization of phytate phosphorus in feed. Since wheat is rich in endogenous phytase activity it was examined whether wheat phytases could improve phytate degradation compared to microbial phytases. Moreover, it was investigated whether enzymatic degradation of phytate is influenced by the matrix surrounding it.

Biotechnological production and applications of phytases
Applied Microbiology and Biotechnology, 2005Phytases decompose phytate, which is the primary storage form of phosphate in plants. More than 10 years ago, the first commercial phytase product became available on the market. It offered to help farmers reduce phosphorus excretion of monogastric animals by replacing inorganic phosphates by microbial phytase in the animal diet.

Adoption of Phytase by Livestock Farmers [PDF]
, 2008 Phytase represents a potential win/win management practice for non-ruminant producers since it can reduce the need for phosphorous supplementation and also result in lower phosphorous runoff. Cost of phytase has decreased and cost of phosphorous has increased.

Distribution of phytase in the rat
Archives of Biochemistry and Biophysics, 1959Abstract Phytase activity has been demonstrated to be widely distributed in the rat, the highest activity being found in the intestinal mucosa. The relative distribution of this enzyme parallels closely the known relative distribution of alkaline phosphatase with the exception of brain which exhibits a high phytase activity in relation to its β ...

THE CHARACTERISTICS OF SOYBEAN PHYTASE
Journal of Food Biochemistry, 1986Soybean phytase was extracted with 2% CaCl2 and partially purified by ammonium sulphate fractionation followed by dialysis in 0.01 M tris-maleate buffer, pH 6.5. The enzyme showed an optimum pH of 4.8 and optimum temperature of 60°C. The phytase was partially inhibited at high substrate concentration, with an optimum substrate concentration at 20 mM ...

Isolation and characterization of a new bacillary phytase
Russian Journal of Bioorganic Chemistry, 2013Bacillus ginsengihumi phytase has been firstly isolated and studied from the recombinant Escherichia coli strain cellular lysates. The enzyme was obtained from the cellular lysate, purified till homogeneous condition, primary structure was determined. It's concluded that phytase relates to beta-propeller class of phosphatases.

Beta-propeller phytases in the aquatic environment
Archives of Microbiology, 2006Phytate, which is one of the dominant organic phosphorus compounds in nature, is very stable in soils. Although a substantial amount of phytate is carried from terrestrial to aquatic systems, it is a minor component of organic phosphorus in coastal sediments.

Phytase: Sources, preparation and exploitation
Folia Microbiologica, 1998This review deals with phytase (myo-inositol hexakisphosphate phosphohydrolase) and covers microbiological sources, phytase occurrence in plants and animals, its purification, physico-chemical and molecular properties. Protein engineering of phytase and potential enzyme applications are discussed.
