PRODUCTION OF FUNCTIONAL BACTERIAL POLYSACCHARIDE FROM MIXTURE OF CARBOXYMETHYL CHITIN AND ITS DERIVATIVE WITH GLUCOSE AS CARBON SOURCE

摘要

PROBLEM TO BE SOLVED: To provide a method for functionalize a bacterial cellulose-like polysaccharide by a low environmental load type means.;SOLUTION: This culture medium for producing the bacterial cellulose-like polysaccharide is characterized by containing a carboxymethyl chitin polymer or oligomer and glucose as carbon sources. The biodegradable polysaccharide is obtained in the culture medium. The method for introducing a desired group into a bacterial cellulose-like polysaccharide is characterized by culturing a cellulose-producing bacterium in a culture medium containing glucose and carboxymethyl chitin polymer or oligomer having a group to be introduced, as carbon sources. The bacterial cellulose-like polysaccharide into which a desired group is introduced by the method.;COPYRIGHT: (C)2005,JPO&NCIPI
