A process for enzymatic preparation of poly (α 1, 3 glucan) from sucrose is disclosed. The glucosyltransferase enzyme (gtfJ) from Streptococcus salivarius is used to convert sucrose to fructose and poly (α 1, 3 glucan). Application of semi-permeable membranes to continuously remove fructose, a by-product of the gtf enzyme, thus increasing the poly (α 1, 3 glucan) liter, is disclosed. |
