Abstract
The present invention relates to a method for biologically producing, from seaweeds, 3,6-anhydro-L-galactitol (L-AHGol) which is a novel sugar alcohol, and agarobititol (ABol) which is in a disaccharide form having 3,6-anhydro-L-galactitol (L-AHGol) as a reducing end, by using a genetic engineering technique in GRAS strains.
Claims12
A method of producing a sugar alcohol using agarobiose as a substrate, comprising
- fermenting a recombinant yeast in the presence of agarobiose and carbon source,
- wherein the recombinant yeast expresses a gene encoding aldose reductase (AR) and a gene encoding lactose permease.
