Summary Optimization of d-(-)-2,3-butanediol production from the Jerusalem artichoke, Helianthus tuberosus, by Bacillus polymyxa ATCC 12 321 is described. The effects of initial sugar concentration and oxygen transfer rate were examined. The latter appears to be the most important parameter affecting the kinetics of the process. The best results (44 g·l-1 2,3-butanediol, productivity of 0.79 g·l-1·h-1) were obtained by setting an optimal k L a profile during batch culture.
