Abstract (en)
[origin: WO9747806A1] The present invention provides methods of making paper utilizing glucans, produced by glucosyltransferase B enzymes of the species Streptococcus mutans, instead of modified starches. The present glucans are functionally similar to the hydroxythyl modified starch and are particularly useful in the sizing and coating steps of paper manufacture. The present glucans also exhibit thermoplastic properties and impart gloss to the paper during the coating step.
