以青黴( penicillium . sp ) ds9701為出發菌株,通過紫外線誘變分生孢子,採用透明圈初篩和搖瓶培養復篩的方法,獲得4個能穩定遺傳的phb解聚酶高產菌株。Specific pichia clony pcr product showed that foreign phytase gene was integrated into the host cell. the experimental results from flask fermentation and phytase activity assay indicated that phytase gene was effectively expressed by the recombinant pichia
挑選轉化子經過bmgy搖瓶培養、 bmmy誘導發酵后,用釩鋁酸按法測定了表達產物的酶活性,結果表明重組菌株可有效表達具有生物學活性的植酸酶。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。Western blot analysis showed that rhpk - 5 ( recombinant human plasminogen kringle 5, rhpk - 5 ) protein was recognized by mab same as native hpk - 5. the result suggested that we obtained correct gene sequence of hpk - 5 and got the purified rhpk - 5. section ii : construction of pbv220 / hpk - 5 vector for obtaining high - level hpk - 5 expression system, the hpk - 5 gene was recombined with plasmid pbv220 to construct the vector of pbv / hpk - 5
