摘要評述了對甲苯磺酸、氨基磺酸、強酸性陽離子交換樹脂、六水三氯化鐵、二水氯化銅、五水四氯化錫、十二水合硫酸鐵銨、一水硫酸氫鈉、硫酸氫鉀、殼聚糖硫酸鹽、磷酸二氫鈉、稀土金屬氧化物、固體超強酸、雜多酸和分子篩等催化劑催化合成乙酸異丁酯的方法。 -
Phytases are a class of phosphatases that 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, has drawn much attention in home and abroard
研究表明，飼料中添加植酸酶可使其中磷利用率提高60 ，糞便中磷排出量減少40 ，還可以提高飼料轉化率，改善動物的生產性能，因此對提高養殖業的經濟效益及環境保護均具十分重要意義。 -
The cadmium content in weathering phosphate rock is nearly two times of original phosphate rock, this demonstrates that under the surrounding of oxidization in the surface of the earth, cadmium is oxidized under the action of acidic water solution and is displaced distinctly
白果坪磷礦風化磷礦中的鎘含量較原生磷礦鎘含量高近一倍，表明在地表氧化環境下，鎘元素在酸性水溶液的作用下被氧化淋濾發生了明顯遷移。 -
Acidic sodium aluminum phosphate
酸式磷酸鈉鋁 -
The soil phosphate activities were determined after 0, 10, 50, 60 days. the results show that alkaline phosphate activity was degressive, acidic phosphate activity changed inconsistently and neutral phosphate activity was ascending slowing. the analyse of the phosphate activity ' s absolute change also shows that the influence of soil algae on phosphate activity is not prominent
結果表明，待測土壤中的堿性磷酸酶活性全部是下降的，中性磷酸酶活性緩』陛上升，而酸性磷酸酶活性的變化沒有太大的規律性，但是總體上還是上升的、其磷酸酶活性絕對變化的方差分析也表明藻類對土壤磷酸酶的影晌不顯著。 -
The 102 strains which can produce hydrolyzed circles were obtained using alternative medium containing phytate - calcium. after being isolated and purified, these strains were inoculated into fermented medium, shaking in 28 c at 220r / min for 5 days, then their enzymatic activities were determined by ammonium molybdate - phosphate colorimertry under the condition of 37 cand ph2. 5. the result showed there were 24 strains with higher enzymatic activities among the 102 strains, after the rescreening, 7 strains were gained with enzymatic activities beyond 15u / ml and stable ability of producing acidic phytase, of which, enzymatic activity of the strain 14 was the highest, reaching 53. 86u / ml, and it was preliminarilly identified as aspergillus. niger, then numbered as aspergillus. niger 14
用植酸鈣選擇性平板培養基從土樣中篩選出了102株能產透明圈的菌株，經分離純化后，接入液體發酵培養基， 28 、 220r min發酵5天，在37 、 ph2 . 5條件下用釩鉬酸銨法測定其所產植酸酶的活力，結果顯示，酶活較高的有24株，經再次搖瓶復篩后，酶活大於15u ml且產酶性能穩定的共有7株，其中以14 ~ #菌株的酶活最高，可達53 . 86u ml ，經初步鑒定為黑麴黴，編號為aspergillus . niger14 ~ # 。 -
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。
