DIRECT FILATURE OF BACTERIAL CELLULOSE FROM CULTURE-MEDIUM

The continuous Filature of bacterial cellulose has been achieved direc tly from culture medium using shallow culture pan newly designed. A re markable progress of fiber properties was observed comparing with rege nerated cellulosic filaments on the filament of bacterial cellulose de pendently on the rinsing process with water or ethylene glycol. The pr ogress of fiber properties was also shown on the filament of N-acetylg lucosamine(GlcNAc) incorporated bacterial cellulose probably due to en forcement of fiber interactions. A copolymer of carboxymethyl-glucose (CM-Glc) and glucose has been achieved successfully to increase the ad sorption capacity for lead ion comparing with original carboxymethyl c ellulose (CMC).
