中文拼音 [mùsuāngài]
鉬酸鈣
英文
calcium molybdate-
A new process for preparing ammonium molybdate by using waste calcium molybdate
利用鉬酸鈣廢物制取鉬酸銨的新工藝The main conclusions with innovative features acquired from the present work are as follows : ( 1 ) soft solution processing technique for preparing functional thin films was put forward and applied to preparing advanced inorganic functional thin films ; a series of molybdate and tungstate films with scheelite - type were prepared directly on metal substrates ( molybdenum and tungsten foils ) by using constant current electrochemical technique at room temperature ; a series of titanate thin films with perovskite - type were synthesized directly on titanium flakes by hydrothermal method in our country for the first time
通過上述研究工作，得到了如下具有創新性研究成果： （ 1 ）首次在國內提出和運用軟溶液制備工藝技術進行無機功能薄膜材料的制備研究；首次在國內採用室溫恆電流電化學技術直接在金屬基底（鉬片和鎢四川大學博士學位論文片）制備了白鎢礦結構的鋁酸鹽、鎢酸鹽薄膜;首次在國內採用水熱合成技術在欽金屬片上直接沛叮備了鈣欽礦結構的欽酸鹽薄膜。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 ~ # 。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。分享友人
