Abstract Through the role of phytase, some soil bacteria can mineralize insoluble organic P such as phytate (myoinositol hexakisphosphate). Phytase is a secreted enzyme possessing ability to hydrolyze into phosphate esters and inorganic for plants absorption. This study aimed isolate phytase-producing from mangrove sediment examine influence nutrients (source carbon, nitrogen, phosphorus) physi...

This experiment was conducted to investigate the effects of supplemental phytase in a corn-wheatsoybean meal basal diet on phosphorus (P) digestibility and performance of broiler chicks. 378 one-day old broiler chicks (Ross 308) were allocated to 3×3 factorial arrangements with three levels of phytase enzyme (0, 500 and 1000 FTU/kg) and three levels of non-phytate P (100, 80 and 60% of NRC requ...

Optimization for enhanced phytase production by Aspergillus oryzae SBS50 in submerged fermentation was investigated using Taguchi design. In first step design, starch, beef extract, magnesium sulphate, ferrous sulphate and Tween 80 were identified as significant factors affecting phytase production. These significant factors were further optimized at four different levels using a second Taguchi...

Phytase can improve the nutritional value of plant-based foods by enhancing protein digestibility and mineral availability through phytate digestion in the stomach and the food processing industry. Microbial sources are more promising for the production of phytases on a commercial scale. The objectives of this exploration were to screening and isolation of phytase-producing bacteria from hot sp...

The aim of this experiment was to compare the responses of young broiler chickens directly with the responses of turkeys to different dietary phytase concentrations. Nine hundred sixty birds (480 female Ross 308 broilers, and 480 female BUT6 turkeys) were reared in 64 floor pens from 0 to 21 d of age. Each species was fed a nutritionally complete (12.79 MJ/kg of AME, 231 g/kg of CP vs. 11.75 MJ...

Phytases are nutritionally important for increased bioavailability of dietary minerals and phosphate for monogastric animals including humans. Release of minerals and phosphate is accomplished by the enzymatic stepwise degradation of phytate (inositol hexaphosphate, IP6). Activity determinations of phytase is often based on analysis of total released phosphate (Pi), but phytase activity in its ...

Phytases (myo-inositol hexakisphosphate phosphohydrolases; EC 3.1.3.8) catalyze the hydrolysis of phytic acid (myoinositol hexakisphosphate) to the mono-, di-, tri-, tetra-, and pentaphosphates of myo-inositol and inorganic phosphate. Therrmophilic bacteria isolated from water sampled from hot spring. About 120 isolates of bacteria were successfully isolated form hot spring water sample and tes...

Background: Exogenous enzyme supplementation is an effective and cost-saving mechanism for increasing the availability of dietary nutrients by digestion reducing excretion. Objective: To evaluate effects phytase on performance, egg quality, economic parameters in commercial laying hens fed reduced-nutrient diets from 70 weeks age. Methods: Novogen White® (n=256) were randomly allocated to four ...

The effects of phytase and tannase enzyme treatment sorghum-based broiler diets on ileal villi characteristics were evaluated in Cobb 500 broilers. A total three sorghum levels, 0, 50, 100%, with 4 levels; 5% phytase, phytase+tannase combination used to develop 12 different dietary treatments. Three hundred sixty broilers randomly allocated the treatments a completely randomized design experime...

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 in a so called premix factory producing animal feed additives, could be due to type I (mediated ...
