Phytase activity in lichens [PDF]
New Phytologist, 2015 Phytase activity was investigated in 13 lichen species using a novel assay method. The work tested the hypothesis that phytase is a component of the suite of surface-bound lichen enzymes that hydrolyse simple organic forms of phosphorus (P) and nitrogen (

Phytases and Phytase-Labile Organic Phosphorus in Manures and Soils
Critical 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 ...

Secreted Phytase Activities of Yeasts [PDF]
Bioscience, Biotechnology, and Biochemistry, 2000 The enzyme phytase dephosphorylates phytin (inositol hexaphosphate), a major phosphate reserve in plants. We found that a large number of yeast species secreted a phytase. Several species were identified as high phytase producers. The yeast enzymes had an optimal activity at pH 4-5 and generally a very high optimal temperature, ranging from 60 degrees ...

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.

Improvement of Fungal Phytase Production and Its In vitro Application in Ruminant Nutrition [PDF]
Arab Universities Journal of Agricultural Sciences, 2021 Various fungal genotypes (Aspergillus niger NRRL 3135 (AN1), Aspergillus niger NRRL 326 (AN26), Aspergillus terrus F2-Kh (AT) and Mucor racemosus NRRL 3639 (MI)) were studied for their ability to produce phytase and improve the produced enzyme by ethyl ...

Citrobacter amalonaticus phytase on the cell surface of Pichia pastoris exhibits high pH stability as a promising potential feed supplement. [PDF]
PLoS ONE, 2014 Phytase expressed and anchored on the cell surface of Pichia pastoris avoids the expensive and time-consuming steps of protein purification and separation. Furthermore, yeast cells with anchored phytase can be used as a whole-cell biocatalyst.

Safety and efficacy profile of a phytase produced by fermentation and used as a feed additive
Heliyon, 2021 Enzymes can aid in optimal feed stock utilization when used as feed additives. A range of toxicological studies were performed to evaluate the safety profile of a novel phytase (phytase HM) from Citrobacter braakii produced in Aspergillus oryzae. Phytase
