Abstract:
This paper described the treatment of itaconic acid strain of Aspergillus terreus As 3 2811 with uv irradiation and high temperature The mutant was obtained which grew in culture media containing succinic acid as the only carbon source Its productivity of itaconic acid was 5 times higher than the original strain The producing acid conditions were optimized by orthogonal experimental design By batch feeding glucose fermentation ,the itoconic acid productivity could be improved by 39 92%
