Abstract

The invention relates to a method for producing 2,3-butanediol using improved strains of Raoultella planticola, and to novel mutant strains obtained by random mutagenesis from the bacterial species Raoultella planticola CECT843, that can be used in the industrial production of 2,3-butanediol from glycerol. The invention preferably relates to the Raoultella planticola strains designated IA1 and IIIA3 and deposited in the Spanish Type Culture Collection (CECT) under deposit number CECT8158 (corresponding to the strain designated IA1) and deposit number CECT8159 (corresponding to the strain designated IIIA3). The invention also relates to a method for producing 2,3-butanediol from glycerol by means of a biotechnological process using the novel strains of the invention.
