摘要： PURPOSE: Chitosan and a method for preparing the chitosan from a biomass of microorganism are provided, to improve the solubility in water and to reduce the viscosity of chitosan. CONSTITUTION: The chitosan which contains a material derived from a biomass of microorganism, is characterized by containing a material making 85 wt% or more of the N-acetyl group of chitin to be deacetylated. Preferably the chitosan comprises further a material containing 0.05% or less of lime. The 1 wt% chitosan solution has a viscosity less than 25 cP, preferably less than 15 cP in 1% aqueous acetic acid solution at a temperature of 25 deg.C. The method comprises the steps of reacting a biomass of chitin in 25% or more alkali hydroxide solution at a temperature above 95 deg.C for at least 10 hours for converting chitin into chitosan; and separating the chitosan from the solution.
