SCREENING OF THERMOPHYLIC MICROORGANISM FROM IJEN CRATER BANYUWANGI AS PHYTASE ENZYME PRODUCER
Phytase is enzyme which hydrolysis phytic acid to anorganic phosphate and myo-inositol pentakis-, tetrakis-, tris-, bis-, and monophosphate. The use of phytase in feed industry can overcome environment and nutrition problems which were arisen from ...

Advances in phytase research [PDF]
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.

Secreted Phytase Activities of Yeasts [PDF]
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 ...

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

Enzymatic association in the diets of laying hens raised in an alternative cage-free system [PDF]
: The objective of this work was to evaluate the use of enzyme combinations in diets, with different nutritional uplift matrices, for hens raised in an alternative cage-free system. The experiment was carried out with 800 Isa Brown laying hens aged 24-30

Effect of divalent metals on phytase activity and enzymatic kinetics of As-hyperaccumulation ferns
Phytase secreted by plant roots can hydrolyse phytate to provide phosphorus (P) for plants growth. To ensure the plant growth and to reduce the pollution caused by heavy metal in environment, this paper studies the phytase activity in environment.

Effect of phytase on phosphorous balance in 20-kg barrows fed low or adequate phosphorous diets
The effects of phytase on phosphorus (P) digestibility are well established. However, there are few studies that report P balance, particularly when phytase is used in diets that have adequate or deficient P.
