    摘要: A methods for altering the metabolite profile of a fermentation, by increasing flux through acetolactate. The methods comprises increasing production of one or more products derived from acetolactate. Further provided is a method for increasing the production of 2,3-butandiol by microbial fermentation of gaseous substrates, the method comprising providing a compound which inhibits one or more enzymes which convert acetolactate to branched chain amino acids to the fermentation. The present invention further provides methods for increasing the production of 2,3-butandiol relative to other fermentation products such as ethanol and acetic acid.

    摘要: A process for producing and controlling pyruvate derived products during the fermentation of a CO containing substrate by an acetogenic carboxydotrophic microorganism has been developed. The process involves increasing the concentration of at least one nutrient selected from the group consisting of vitamin B1, vitamin B5, vitamin B7 and mixtures thereof above the cellular requirement of the microorganism. When the concentration is increased, the production of 2,3-butanediol (2,3-BDO) increases whereas the production of the other metabolites is virtually unchanged. The effect is reversible so that when the concentration is decreased, the production of 2,3-BDO is also decreased. This allows one to control the ratio of ethanol:2,3-BDO to a desired value which can vary from about 4:1 to about 1:2.
