Abstract

In order to improve the production of bacterial alginate, Azotobacter vinelandii NCIB 8789 was treated with 200.$\mu$g/ml of MNNG for obtaining mutant strain. The mutant HB18 was selected, which produced the highest amount of alginic acid among the survival stains. The HB18 produced 5.4g/l of alginic acid when batch cultured at $30^{\circ}C$ for 160 hrs and its alginic acid showed high molecular weight and simple composition when compared with thoseof wild type.
