Research status of Bacillus phytase
3 Biotech, 2021Phytic acid is abundant in seeds, roots and stems of plants, it acts as an anti-nutrient in food and feed industry, since it affects the absorption of nutrients by humans and monogastric animals. Furthermore, phosphorus produced through its decomposition by microorganisms can cause environmental pollution.

Microorganisms as phytase producers
Microbiology, 2012Replenishing of the stores of inorganic phosphate is among the most urgent environmental problems. In soil, phosphorus within inorganic compounds is mostly (over 80%) present as insoluble, phytic acid-based conglomerates. Phytates are strong chelating agents, binding the cations of bivalent metals, as well as peptides and low-molecular metabolites into

Diversity of Phytases in the Rumen
Microbial Ecology, 2006Examples of a new class of phytase related to protein tyrosine phosphatases (PTP) were recently isolated from several anaerobic bacteria from the rumen of cattle. In this study, the diversity of PTP-like phytase gene sequences in the rumen was surveyed by using the polymerase chain reaction (PCR).

The phytases. I. Lysolecithin-activated phytase from wheat bran
Biochimica et Biophysica Acta (BBA) - Enzymology, 19711. 1. Myo-Inositol hexaphosphate phosphohydrolase (EC 3.1.3.8, phytase) from wheat bran may be separated by DEAE-cellulose into two fractions (F1 and F2) which yield different substrate degradation patterns. 2. 2. Fraction F1 contains a lipid activator whose properties are consistent with those of lysolecithin.

Of all the sources of phytase that have been studied (plant, animal, and microorganisms), the highest yields are produced by a wild-type strain A. niger NRRL 3135 (12.7 mg P/hr/ml = 6.8 microns P/ml/min = 113.9 nKat/ml) in a mineral salt medium in which total phosphate (4 mg %) is limiting for growth and cornstarch and glucose are the carbon sources ...

Phytase properties and locations in tissues of transgenic pigs secreting phytase in the saliva1
Journal of Animal Science, 2014A transgenic Cassie (CA) line of Yorkshire (YK) pigs was developed using a transgene composed of the mouse parotid secretory protein promoter linked to the Escherichia coli phytase gene integrated in chromosome 4. Previous studies documented that salivary secretion of phytase was sufficient to enable efficient digestion of plant feed phytate P.
