【Abstract】 Trehalose is a naturally occurring disaccharide which consists of two glucose molecules linked by a 1,1- a -glycosidic bond. Trehalose occurs in bacteria, yeast (e.g., S. cerevisiae), a wide variety of fungi, algae, and a few higher plants. Intracellular trehalose appears to play an important role in the protection of the cells from dehydration and freezing, as well as from other adverse environmental conditions (e.g., heat shock, toxic levels of ethanol, osmotic stress). In addition, trehalose may serve as reserve carbohydrate during periods of carbon starvation. The enzymes which are used in the production process of trehalose are obtained from non-genetically modified strains of arthobactersp.pseudomonas amyloderamosa, bacillus stearothermophilus, aspergillus niger, and bacillus subtilis, sulfolobus acidocaldarius. The paper discusses the synthesis of trehalose and enzymes that are used in the production of trehalose.更多还原
