Claim:
1. A method for producing 1,2-propanediol by fermentation, comprising: a) cultivating a strain of b) recovering the 1,2-propanediol being produced, wherein the strain of is genetically modified to comprise a non-phosphotransferase system (non-PTS) sucrose utilization system with the introduction of the genes cscBKAR, wherein the gene cscB codes for a sucrose:proton symport transport system, the gene cscK codes for a fructokinase, the gene cscA codes for an invertase, the gene cscR codes for a sucrose specific receptor, and is able to utilize sucrose as a sole carbon source for the production of 1,2-propanediol.
