Abstract:
The production of 2, 3-butanediol and succinic acid by a moderate halophile under anaerobic condition was investigated. This halophile, termed Salinivibrio YS, was isolated from the solid samples collected from Aydingkol Lake. Based on the single factor experiment, the parameters and their values for the production were obtained. Then, the optimum values of these parameters by the orthogonal experiments were obtained: temperature, 33 degrees C; initial pH of fermentation, 8.0; the pH during fermentation, 7.0; the concentration of acetic acid was 3 g/L and NaC1 was 10 g/L. Finally, a 3-L fermentation based on these conditions was carried out. After 108 h of fermentation under anaerobic condition, 35.05 g/L of 2, 3-butanediol and 22.46 g/L of succinic acid were obtained. About 50% of total glucose conversion was achieved. The study on 2, 3-butanediol and succinic acid by a halophile under anaerobic condition will expand the applications of halophiles and open a new area of production of 2, 3-butanediol and succinic acid.
