Increased poly (α 1, 3 glucan) yield using boric acid

摘要

A process for production of poly (α 1, 3 glucan) from a renewable feedstock, for applications in fibers, films, and pulps. The effect of addition of boric acid in increasing the yield of the desired end products, poly (α 1, 3 glucan) and fructose, and decreasing formation of the undesired by-product leucrose.

主权项

1. A reaction solution for the synthesis of poly (alpha 1,3 glucan) comprising:
a) at least one Streptococcus glucosyltransferase enzyme that synthesizes poly (alpha 1,3 glucan) from sucrose; b) boric acid; and c) sucrose,whereby poly (alpha 1,3 glucan) is produced with a lower concentration of leucrose by-product than is produced in the absence of boric acid.
