Traditional cellulose production from cellulosic biomass for industrial purpose was complicated. The pulping process from cellulosic biomass caused various problems such as the exhaustion of forest resources and environmental pollution; exclusion of polychlorinated dioxins, furans, persistent organics, sulfur oxides, nitrogen oxides, carbon monoxide etc. These toxic chemical materials cause air, water, soil pollution. However, bacterial cellulose produced by acetobacters
strains is free from lignin, hemicelluloses and thus, it does not need chemical chlorine bleaching process. Bacterial cellulose has unique properties including an ultra-fine fiber network, high purity, and high crystallinity. It shows more than five times higher tensile strength and six times higher elasticity coefficient than plant cellulose. With these unique physico-chemical properties bacterial cellulose is used for various industrial purposes. In this study, the effect of water soluble
oligosaccharide on production of bacterial cellulose was investigated in the view point of metabolic pathway. We could get high improvement in bacterial cellulose productivity by adding 0.5-4% (w/v) water soluble oligosaccharide to the medium. BC water holding capacity was improved.
