Phytases are phosphatases that can break down the undigestible phytic acid (phytate). They are frequently used as an animal feed supplement - often in poultry and swine - to enhance the nutritive value of plant material by liberation of inorganic phosphate from phytate. Exposure to enzyme dusts has
Phytase 50104 enzyme (also known as VR003) can be added to swine and poultry diets to catalyze the hydrolysis of phosphate from phytic acid, thereby increasing phosphorus bioavailability in these animals. This enzyme was produced from a Pseudomonas fluorescens (P. fluorescens) production strain and
The food enzyme Myo-inositol-hexakisphosphate 4-phosphohydrolase (4-phytase, EC 3.1.3.26) is produced with a genetically modified Trichoderma reesei DP-Nzt55 by Danisco US Inc. The production strain contains a known antimicrobial resistance gene. However, based on the absence of viable cells
OBJECTIVE
Phytase is a phosphatase derived from Aspergillus niger that enhances phosphate bioavailability in the gut, and therefore has been increasingly used as an animal feed additive since the early 1990s. The aim of this study was to assess whether work related respiratory symptoms among workers
The immune response of aged broiler breeder hens is influenced by many factors including obesity and aged lymphatic organs, but may improve by increasing the bioavailability of various nutrients such as zinc (Zn). Dietary supplementation of phytase can improve Zn availability in 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. One problem
BACKGROUND
Industrial enzymes cause the increasing prevalence of occupational hypersensitivity. Our objective was to study workers occupationally exposed to fungal enzymes in 2 animal feed factories to determine if the sensitization originated in the enzymes or was caused by the microorganism used
The use of genetically engineered enzymes in the synthesis of flavourings, fragrances and other applications has increased tremendously. There is, however, a paucity of data on sensitisation and/or allergy to the finished products. We aimed to review the use of genetically modified enzymes and the
