中文拼音 [zhèguǒsāntáng]
蔗果三糖
英文
gf2-
The growth of f - 16 and the production of enzyme were affected by microbial medium, including c source, n source, mineral, initial ph of medium, rotating rate, culture time and culture temperature. the results showed that the optimal n sources were peptone, corn steep liquor and yeast extract ; the optimal c sources were sucrose, glucose and maltose ; the optimal minerals were mgso4 7h2o, khpcu and cuso4 5h2o
實驗表明，氮源中蛋白腖、玉米漿、酵母粉比較好；碳源中蔗糖、葡萄糖、麥芽糖這三種糖對產酶和生物量提高效果顯著；無機鹽中mgso _ 4 ? 7h _ 2o ， k _ 2hpo _ 4 ， cuso _ 4 ? 5h _ 2o對產酯酶的酶活及其反應后所得水解液的光學純度有較好的作用。Fos contain mixture of gf2, gf3 and gf4 sugars ( where g = glucose molecule and f = fructose molecule ) and a dp ( “ degree of polymerization ” ) of 3 - 5 ( “ neosugar ” ), are not naturally - occurring but are enzymatically synthetized from sucrose by action of an enzyme from the fungus aspergillus niger
詳細說明：是以蔗糖做底物，採用呋喃果糖苷酶轉果糖基作用，在蔗糖分子上以（ 1 2 ）糖苷鍵上與1 - 3個果糖分子結合，形成的蔗果三糖（ gf2 ） 、蔗果四糖（ gf3 ） 、蔗果五糖（ gf4 ）屬于果糖和蔗糖構成的直鏈雜低聚糖，在形成的產物中還有果糖、葡萄糖和未反應完全的底物蔗糖，採用色譜法除去單糖和雙糖制得高純度的低聚果糖。In this study, systems of rapid propagation of the cultivars such as d. zingiberensis, d. panthaica and d. composite were setup to find the best way to meet the need of producing, and to establish the base of introduction, breeding and cultivar improvement of foreign dioscorea with high diosgenin ; in addition, there are two strategies to obtain polyploids combining with chromosome engineering : screeding natural mutations and mutation breeding were carred out on d. zmgiberensis. exploratively studies were done on rapid propagation of the three dioscorea plants. the result showed : explants of d. pathaica obtained the appreciate propagation efficency on ms + ba1. 0mg / l + naa0. 1mg / l, ms basic medium containing 6. 0mg - 1 ba, l. 0mg - 1 kt and sucrose at 30gl - 1 or 60g1 - 1 was the appreciate medium for microtuberization
三種薯蕷屬植物離體再生體系培養條件的探索試驗結果表明：黃山藥外植體適宜的增殖培養基為ms + ba1 . 0mg / l + naa0 . 1mg / l ，微型塊莖誘導為ms + ba6 . 0mg / l + kt1 . 0mg / l + 3蔗糖，高濃度的蔗糖含量（ 6 ）能提高微型薯蕷的誘導率，但對其誘導起關鍵作用的還是ba的濃度；菊葉薯蕷增殖效果較好的培養基為ms + ba1 . 0mg / l ，以ms培養基為誘導微型薯蕷的最佳選擇，誘導率可達50 ；盾葉薯蕷最適宜的增殖培養基為ms + ba2 . 0mg / l ，在誘導微型薯蕷的實驗中發現，當ba濃度為6 . 0mg / l和8 . 0mg / l時， 15d左右節間處膨大形成綠色圓球狀小塊，但繼續培養其上則開始分化芽。
