The present invention relates to modified microorganisms with increased methylglyoxal reductase activity, and to their use for the preparation of 1,2-propanediol and / or acetol. Specifically, the increased methylglyoxal reductase activity is achieved by increasing the expression of specific genes from the microorganism. The invention also relates to a process for producing 1,2-propanediol and / or acetol by fermentation of microorganisms with increased methylglyoxal reductase activity. |
