Screening of microorganisms for the production of alginate was conducted, and cultivation conditions were optimized for developing new functional materials for the polymer. For the screened Azotobacter vinelandii IAM 1078,several saccharides, e.g., sucrose, glucose, fructose, and organic acid salts, e.g., succinate were tested as carbon sources. Of these substrates, sucrose was found to give both the best cell mass and best alginate production. Under the optimum conditions, alginate accumulation reached 4.9 g/l, the highest consistency ever reported. The alginate was estimated to be 225 kilodalton in molecular weight and to have a mannuronate to guluronate ratio of 0.31,which is lower than that of previously reported bacterial alginate.
