  1. According to these problems, we adopt to the method of mending material, optimize to fermentation media and partly ferment condition. finally, we excogitate a kind of fermentation technology that is suitable for target gene efficiency expressed and is advantageous of product purified. with the plasmid pbv220 - ifnr, pbv220 - hgfa, pbv220 - hgfb, pbv220 - hpk5 that expresses serve as the model, adopting the biostat - c15l of b. braun company, utilize the method of mending material to ferment, through optimization fermentation media and optimization partly ferment condition ( ventilate quantity, stir speed, mend material speed ), eventually establishment a kind of fermentation technology that is suitable for target gene efficiency expressed and is advantageous of product purified

    以我室構建並穩定表達的重組質粒pbv220 - - ifn 、 pbv220 - hgf 、 pbv220 - hgf 、 pbv220 - hpk5為模型,分別從不同的表達宿主菌中篩選出一種適合大規模生產的菌種bl21 ( de3 ) ,該工程菌株連續傳代100代表達質粒不丟失,表達量穩定;採用b . braun公司的biostat - c15l自控發酵罐,運用分批補料技術分別進行四種工程菌的高密度發酵,通過優化工程菌發酵的培養基配方及優化部分發酵條件(通氣量、攪拌速度、補料速度) ,最終建立一種適于目的基因高效表達的高密度發酵工藝模式。
  2. The transgenic plants have been studying for more than ten years, which have some advantages including that the plants are autotrophy not requiring expensive media or strict culture conditions, and the plant viruses cannot infect human, compared with other systems such as microbe fermentation and transgenic animals

    與微生物發酵、動物細胞和轉基因動物等生產系統相比,轉基因植物不需要昂貴的設備和嚴格的培養條件,具有光合自養、成本較低,植物病毒不感染人類等優點,已成為一類比較廉價和安全的生物反應器。
  3. Purification and characterization of phytase from a. niger an 01001 a. niger an01001 was inoculated on solid media and cultivated at 30 for 5 days. proteins were extracted from solid - state fermentation with 50mm acetate buffer ( ph5. 5 ). the molecule weight of the phytase protein was determined as about 78kd by sds - page. the purification procedures include ammonium sulfate precipitation, deae - cellulose ion - exchange chromatography, gel electrophoresis and electroelution
