E. Machova et al., ENZYMATIC AND ULTRASONIC DEPOLYMERIZATION OF CARBOXYMETHYLATED BETA-1,3-D-GLUCANS DERIVED FROM SACCHAROMYCES-CEREVISIAE, Journal of applied polymer science, 55(5), 1995, pp. 699-704
Enzymatic and ultrasonic degradations of the carboxymethyl derivative
of the beta-1,3-D-glucan, isolated from the cell walls of baker's yeas
t Saccharomyces cerevisiae, are described. The samples obtained upon p
artial depolymerization of the two carboxymethylated glucans with the
substitution degree of 0.56 and 0.91 were characterized by the distrib
utions of their molecular weights and C-13-NMR spectra. (C) 1995 John
