Abstract
The present invention provides methods of making paper, utilizing glucans, produced by the glucosyltransferase B, C or D enzyme of the species Streptococcus mutans, instead of modified starches. The present glucans are functionally similar to currently utilized modified starches and are particularly useful in the coating step of paper manufacture. The present glucans also exhibit thermoplastic properties and impart gloss to the paper during the coating step.
Claims14
A method of manufacturing paper comprising adding a glucan to one or more steps in paper manufacturing, wherein the glucan is synthesized by a glucosyltransferase B or glucosyltransferase D enzyme, wild-type or mutant.
A method of imparting gloss on paper during the manufacturing process comprising adding a glucan to a coating step, wherein the glucan is synthesized by a glucosyltransferase B or glucosyltransferase D enzyme, wild-type or mutant.
