Phytases and Phytase-Labile Organic Phosphorus in Manures and Soils

open access: yesCritical Reviews in Environmental Science and Technology, 2013
Organic phosphorus (Po) hydrolysis by microbial phytases has extensively been considered in diverse biotechnological applications, including environmental protection and agricultural, animal, and human nutrition. The authors review the available information on the content of phytase-labile Po in manures and soils, as well as the environmental factors ...

The phytases. I. Lysolecithin-activated phytase from wheat bran

Biochimica et Biophysica Acta (BBA) - Enzymology, 1971
1. 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.

Phytase fromAspergillus niger

Folia Microbiologica, 1994
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.

Phytase

1996
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 ...

Research status of Bacillus phytase

3 Biotech, 2021
Phytic 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.
