Assessment of the feed additive consisting of 6-phytase (produced with <i>Trichoderma reesei</i>CBS 126897) (Quantum® Blue) for the renewal of its authorisation for poultry, weaned piglets, pigs for fattening and sows (4a19), and its extension of use to other porcine species and ornamental birds (AB Enzymes Finland Oy). [PDF]

open access: yesEFSA J
Abstract Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of the feed additive consisting of 6‐phytase produced with a genetically modified strain of Trichoderma reesei (CBS 126897) (Quantum® Blue) as a zootechnical feed additive for poultry, piglets, pigs for fattening and sows,

Secreted Phytase Activities of Yeasts [PDF]

open access: bronzeBioscience, 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 ...

Phytase activity in lichens [PDF]

open access: yesNew Phytologist, 2015
Summary 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 (N) deposited onto the thallus surface.

Insights into the morphology-productivity relationship of filamentous fungi through small-scale cultivation and automated microscopy of Thermothelomyces thermophilus. [PDF]

open access: yesBiotechnol Prog
Abstract Filamentous fungi are a cornerstone in the biotechnological production of enzymes, proteins, and organic acids. However, challenges in understanding and controlling the relationship between morphology and productivity can limit their application.

Transgenic soybean expressing a thermostable phytase as substitution for feed additive phytase [PDF]

open access: yesScientific Reports, 2019
AbstractPhytase is one of the most effective feed additives to increase the availability of phosphorus and minerals by catalyzing the hydrolysis of phytic acid. A modified appA gene (mappA) was transformed into soybean (Glycine max) under the control of a seed-specific promoter from common bean (Phaselous vulgaris).

Isolation of Phytase Producing Bacteria and Optimization of Phytase Production Parameters [PDF]

open access: yesJundishapur Journal of Microbiology, 2013
Background: Cereals, legumes, and oilseed crops are very important crops as nutrition for human and animals. Phytate (myo inositol hexa kis phosphate) is the main storage form of phosphorus in these crops. These crops are major source of nutrients for humans and animals including fish, poultry and pig.

Advances in phytase research [PDF]

open access: yes, 2000
Since its discovery in 1907, a complex of technological developments has created a potential $500 million market for phytase as an animal feed additive. During the last 30 years, research has led to increased use of soybean meal and other plant material as protein sources in animal feed.

Phytate and phytase in fish nutrition [PDF]

open access: yesJournal of Animal Physiology and Animal Nutrition, 2011
SummaryPhytate formed during maturation of plant seeds and grains is a common constituent of plant‐derived fish feed. Phytate‐bound phosphorus (P) is not available to gastric or agastric fish. A major concern about the presence of phytate in the aquafeed is its negative effect on growth performance, nutrient and energy utilization, and mineral uptake ...

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 ...
