查询词典 phytase

Many research indicated that addition of microbial phytase can increase the bioavailability of P in feed significantly, even when thelevel of P in diet is close to the level of nutrition requirement recommendation, addition of phytase can still improve the apparentabsorption of P in pig and poultry and enhance the bone ash.

大量研究表明添加微生物源植酸酶，能明显提高日粮植酸磷的生物学利用率，即使日粮磷水平已接近营养需要推荐水平，添加植酸酶还可进一步提高畜禽对磷的表观吸收、增加脚掌切力和骨灰分。

Experiment 2, an in-vitro study, was conducted to determine the dialyzability of phosphorus in different plant feedstuffs as experiment 1, with phytase supplementation (500 FTU/kg) and no phytase, respectively, and to research the relationship between the dialyzability with no phytase and apparent or true phosphorus digestibility.

试验2采用体外透析法研究了不同植物饲料(待测植物饲料同试验1)在添加植酸酶(500FTU/kg)和不添加植酸酶情况下磷的体外透析率，并探讨了不同植物饲料在不添加植酸酶情况下磷的透析率与其体内表观消化率和真消化率间的相关关系。

Phytase mainly comes from plant and organism, phytase of plant belongs to 6-phytase and it s optimum pH ranges from 5.0 to 7. 5. Plant phytase can not function effectively in monogastric animals and it is not rich in plant. So research direction about phytase is turned to Aspergillus niger which is rich in acid phytase.

植酸酶主要来自于植物和微生物，来源于植物的植酸酶均属于6—植酸酶，最适pH范围在5.0—7.5，不适合在单胃动物中起作用的，而且在植物中含量极低，因此植酸酶的研究方向转向最适pH值为酸性、酶含量较高的丝状真菌。

Phytase can add to the feed of monogastric animals and hunan food. The addition of phytase to feed and food can resolve the antinutrition of phytic acid, increase the bioavailablity of protein and minerals, decrease animals' fecal phosphorus excretion and reduce environment pollution.

植酸酶可添加于食品与饲料中，能消除因不能降解的植酸所引起的抗营养作用，提高机体对蛋白质及多种微量元素的利用率，降低粪便中磷的含量，从而减少环境中磷的积累污染，有利于保护生态环境。

There isn't a perfect product of phytase while tens kind of phytase product came out.

虽然国内外已经有数种植酸酶商品问世，但还没有一种非常完美的产品。

This paper reports the property of phytase, the structure and function of its gene and the advances in gene engineering of phytase, with a view to discuss the application prospects.

本文谨对植酸酶的性质、基因结构和功能及其基因工程的研究进展做一综述，并探讨了植酸酶的应用前景。

To study the influences of diets with different calcium and phosphorus levels and with added phytase on the fattening results of egg-type cockerels,600 one day egg-type cockerels were divided into three groups and fed with diet in which higher level of Ca and P were designed according to the National Feed Standard of Broilers,low Ca-P level diet which contained 50%CaHPO4 of the control group and diet which was added with 0.2 g.kg－1 phytase on the basic diet of group Ⅰ respectively.

600只1日龄商品代蛋公雏被均等分为3组，分别给以按国标肉仔鸡饲养标准设计的高钙磷日粮，将CK组磷酸氢钙减少50%设计的低钙磷水平日粮及在试Ⅰ组基础上按每kg日粮添加0.2 g植酸酶，探讨不同钙磷水平及添加植酸酶对育肥蛋公雏饲养效果的影响。

In addition, phytase had great applicable foreground for the addition of phytase to feedstuffs because it had a widespread application in food and medicament et al.

此外，植酸酶制剂在食品、医药等方面有广泛的应用。所以，植酸酶作为一种饲料添加剂，有着广阔的应用前景。

The phytase gene was cloned in this study would not only provided excellent gene resource which could express in the microbe and plant but also remedied the vacancy of phytase gene cloned in the funguses.

本研究所克隆的植酸酶基因不仅为植酸酶进一步在各种微生物、植物中表达提供了优良的基因源，而且弥补了食用菌中克隆植酸酶基因的空白。

This gene, together with a phytase gene ( 168phyA) identified in the B. subtilis strain 168 genome by a homology search, was cloned and over-expressed in B. subtilis using a phi105MU331 prophage vector system. Up to 35 units of phytase/ml were secreted into the culture media; and mature enzymes of around 44-47 kDa were purified for characterization.

借助于ф105MU331前噬菌体载体系统，这个基因和另一个通过同源性研究并在B.subtilis菌株168的基因组中被鉴定的植酸酶基因(168phyA)，于B.subtilis中得到克隆和过度表达。B.subtilis菌体向培养基中分泌了高达35个单位的酶夜，同时分子量在44-47kDa之间的成熟酶得到纯化。
