Abstract: Low synthesis yields of the l-ascorbic acid (l-AA) derivative 2- O-α-d-glucopyranosyl-l-ascorbic acid (AA-2G) limit its application in the food industry. In this work, the AA-2G synthesis yield of Bacillus stearothermophilus NO2 cyclodextrin glycosyltransferase (CGTase) was… read more here.
