| 摘 要： | 通过测定氧化葡萄糖酸杆菌转化L－山梨糖中成ZKGA的细胞酶活性、摇瓶发酵及中长变化，研究了Vc:步发酵中巨大茅孢杆菌对氧化葡萄糖酸杆菌生长和产酸作用的影响。结果显示：巨大芽孢杆菌胞外液和胞内液均可促进氧化葡萄糖酸杆菌的增殖，主要表现为缩短其中长周期中的延迟期；巨大芽孢杆菌通过所产生的部分生物活性物质增强氧化葡萄糖酸杆菌产酸的细胞酶活性，促进氧化葡萄糖酸杆菌转化L一山梨糖生成2KGA.

| Abstract: | h relationship between Gluconohacter oxydans and Bacillus megadrium in VtdrinC two- step fermenation process was studied by deteimning the cell enzymic activity syn-thesizing 2KGA from L - sorbose of G. oxydans and the growth of The resultsshowed that both of the culture supernatantaand cytosol of BB. megaterium could promote theproliferation of G. oxydans and B. megaterium could enhance the ability of G. oxydans toconvert L - sorbose to 2 - Keto - L - gulonic acidyreleasing some bioactive metabolities which can enhance the cell enzymic activity of G. axydans . |
