PRODUCTION OF WATER ABSORBING HIGH-MOLECULAR WEIGHT SUBSTANCE

摘要

PURPOSE:To obtain the subject substance, excellent in water absorptivity and water holding ability for an aqueous solution of a metal salt and having biodegradability by culturing Agrobacterium.radiobacter JSR13 strain in a culture medium containing a carbon source. CONSTITUTION:Agrobacterium.radiobacter JSR13 strain (FERM P-11291) is aerobically cultured in a culture medium containing a carbon source (e.g. glucose or sucrose) preferably at 28 deg.C and pH4-8 for 40-50hr to afford the objective substance.
