13. EFFECTS OF THE COMBINATION OF NON-PHYTATE PHOSPHORUS, PHYTASE AND 25-HYDROXYCHOLECALCIFEROL ON THE PERFORMANCE AND MEAT QUALITY OF BROILER CHICKENS
ABSTRACTThis experiment was conducted to evaluate the combination effect of low dietary non-phytate phosphorus (NPP) concentrations, phytase (PHY) levels, and 25-hydroxycholecalciferol (25-OH-D3) levels on the growth performance and meat quality of broilers. Two levels of NPP, two levels of PHY, and two levels of 25-OH-D3 resulted in a 2�2�2 factorial ar

14. Isolation of a thermostable acid phytase from Aspergillus niger UFV-1 with strong proteolysis resistance
An Aspergillus niger UFV-1 phytase was characterized and made available for industrial application. The enzyme was purified via ultrafiltration followed by acid precipitation, ion exchange and gel filtration chromatography. This protein exhibited a molecular mass of 161 kDa in gel filtration and 81 kDa in sodium dodecyl sulfate polyacrylamide gel electrophor

15. Chemical composition and effects of micronized corn bran on iron bioavailability in rats
The degermination of corn grains by dry milling generates 5% of a fibrous residue. After segregation and micronization, corn bran becomes a potential source of dietary fiber consumption. However, its effect on iron bioavailability has not been reported in the literature. The objective of the present study was to determine the nutritional composition of corn

16. Phytate decreases oxidative damage caused by labile forms of iron in solution, blood plasma and in HeLa cells
Fitato (PHYT, mio-inositol 1,2,3,4,5,6-hexakisfosfato) é um produto natural com forte efeito sobre a biodisponibilidade de minerais, especialmente o ferro. Neste trabalho, investigamos os efeitos antioxidantes do PHYT em modelos de transtornos de sobrecarga de ferro (ferro lábil plasmático e reservatório de ferro lábil). PHYT apresentou um efeito antiox

17. Effect of preparation practices and the cowpea cultivar Vigna unguiculata L.Walp on the quality and content of myo-inositol phosphate in akara (fried bean paste)
Akara is one of Brazil's national treasures prepared from cowpea (Vigna unguiculata L.Walp), grated onions and salt and deep-fried in crude palm oil. The results of this study on akara preparation methods showed that, in general, cowpeas were soaked for up 3 hours at room temperature, and the seed coats were then removed. The akara makers preferred the olho

18. Influence of Annona muricata (soursop) on biodistribution of radiopharmaceuticals in rats
PURPOSE: To evaluate the effect of hydroalcoholic extract of A. muricata on biodistribution of two radiopharmaceuticals: sodium phytate and dimercaptosuccinic acid (DMSA), both labeled with 99mtechnetium.METHODS: Twenty four Wistar rats were divided into two treated groups and two controls groups. The controls received water and the treated received 25mg/kg/

19. Isolation, morphological and molecular characterization of phytate-hydrolysing fungi by 18S rDNA sequence analysis
Phytate is the primary storage form of phosphate in plants. Monogastric animals like poultry, pigs and fishes have very low or no phytase activities in their digestive tracts therefore, are incapable to efficiently utilize phytate phosphorus from the feed. Phytase from microbial sources are supplemented to feedstuff of these to increase the uptake of phytate

20. The ileum as a determinant organ of the functional liver cell mass in rats
PURPOSE: To evaluate if the ileum resection changes the functioning liver cell mass, the hepatic metabolism and the biodistribution of radiopharmaceutical in rats. METHODS: Twelve Wistar rats weighing 285g±34g were randomly divided into the ileum resection group (n = 6) and sham group rats (n = 6). After 30 days, they were anesthetized and 0.1mL of 99m-Tc-p

21. Effect of ph and temperature on the activity of phytase products used in broiler nutrition
The activity of three commercial microbial phytase (Aspergillus oryzae, A. niger, and Saccharomyces cerevisae) products used in broiler nutrition was determined at different pH (2.0 to 9.0) and temperature (20 to 90°C) values. Enzymatic activity was determined according to the reaction of the phytase with its substrate (sodium phytate), in four replicates,

22. Fermentation and enzyme treatments for sorghum
Sorghum (Sorghum bicolor Moench) is the fifth most produced cereal worldwide. However, some varieties of this cereal contain antinutritional factors, such as tannins and phytate that may form stable complexes with proteins and minerals which decreases digestibility and nutritional value. The present study sought to diminish antinutritional tannins and phytat

23. Produção, caracterização bioquímica e purificação de fitase produzida por Aspergillus niger var. phoenicis URM 4924.
During ripening, vegetable seeds and grain accumulated substantial amount of phytic acid, representing over 60% of total phosphorus in them. Phytate acts as an energy source for seed germination and is rarely available for non-ruminants, since they do not synthesize the enzyme. Due to the unavailability of biological organic phosphorus in many vegetable food
