This invention relates to a sugar converting method by utilizing entire cell, specially a oligosaccharide fabricating method by utilizing entire cell sugar. Actually relates a fabricating method including: converting a recombining carrier containing new promotor and heat-resistant beta-galactosidase into recombining microorganism of said recombining carrier and utilizing heat-resistant property of said recombining microorganism. According to the oligosaccharide fabricating method of this invention , by utilizing the heat-resistant enzyme, not only a conversion rate of oligosaccharide that equals to the one through a current technology by utilizing refine enzyme is obtained, but also a product cost is reduced greatly due to the production of the enzyme does not need any other process besides a cell cultivation process. |
