phytate -phosphatase 中文意思是什麼

phytate -phosphatase 解釋

  1. Monogastric animals, such as pigs and poultry, are not able to utilize phytate phosphorus efficiently, since they have only low levels of phytase activity in their digestive tracts, phytate also acts as an antinutritional agent in monogastric animals by chelating various microelements needed by the animal

  5. In total 102 strains of acidic phytase producing strains were selected from soil by selective plate containing calcium phytate. among them 32 strains with relatively large clear circle were purified and re - selected by shaking - culturing. after fermented for 5days at 28 c and shaking at 220r / min, the activity of phytase was determined by nh4vo4 - ( nh4 ) 6mo7o24 method at 37 c and ph2. 5 or ph5. 5

    主要結果如下： 1植酸酶高產菌株的篩選利用植酸鈣選擇性子板培養基從土樣中篩選出102株酸性植酸酶產生菌，從中挑選出透明圈較大的菌株32株，經分離純化後分別進行搖瓶復篩， 28 、 220r / min發酵5天後，在37 、 ph2 . 5或ph5 . 5條件下用釩鉬酸銨法檢測其酶活，結果發現有3株菌產酶活性較高且產酶性能較為穩定。
  6. Phytases are hydrolytic enzymes that initiate the release of phosphate from phytate, the major phosphorus ( p ) form in animal feeds of plant origin. phytases are found naturally in microorganisms and plants

    植酸是植物性飼料中磷的主要貯存形式，植酸酶是一種能將植酸水解並釋放出無機磷的酶，它廣泛存在於微生物與植物中。
  7. Phytases catalyze the hydrolysis of phytic acid or phytate ( myo - inositol hexakisphosphate ) to inositol and inorganic phosphate. their roles in eliminating anti - nutritional effects of phytate in plant fodder or foods, in increasing the efficiencies of protein and various microelement utilizations in the animal body and the animal productivities, in reducing the amount of phosphorus in animal excretions and thus reducing environmental pollutions, etc, have been the research focuses domestically and internationally

    植酸酶是一類能催化植酸及植酸鹽水解成肌醇和無機磷酸鹽的酶，它具有解除植物性飼料（或食品）中植酸的抗營養作用、提高機體對蛋白質及多種微量元素的利用率、促進生長發育、提高動物生產性能、減少糞便中磷的排放量、降低磷對環境的污染等多種功能，因而受到國內外的廣泛關注。
  8. Phytase is a kind of enzymes which can catalyze the hydrolysis of phytate into myo - inositol and phosphate. it can relieve anti - nutrition of phytate and improve the nutritional value of animal feed from plant, the study on phytase, especially acidic phytase produced by micro - organism, is paid much attention by scientists in our country and abroard

    植酸酶是催化植酸及植酸鹽水解成肌醇和無機磷酸鹽的一類酶，它能夠解除動物植物性飼料中植酸的抗營養作用，提高植物性飼料的營養價值，因而受到國內外廣泛關注，尤其是微生物所產生的酸性植酸酶。
