Abstract
The present invention relates to a novel method for purifying 3,6-anhydro-L-galactose by using microorganisms and provides an effect of improving the production yield of 3,6-anhydro-L-galactose by using microorganisms during purification after enzymatic hydrolysis of agarose or agar.
Claims14
A method for purifying 3,6-anhydro-L-galactose using microorganisms, comprising:
- reacting a group of enzymes including a thermostable agarase represented by an amino acid sequence set forth in SEQ ID NO:
- 1, an exo-type agarase and an α-neoagarobiose hydrolase with agarose or agar as a substrate;
- culturing a microorganism having an ability to metabolize galactose using a product obtained from the above reaction as a carbon source;
- and
- obtaining 3,6-anhydro-L-galactose from a culture of the microorganism.
