RT Patent T1 Method for producing 2,3-Butanediol using improved strains of raoultella planticola A1 Rojas Martínez, Antonia María A1 Segarra Manzano, Silvia A1 Tortajada Serra, Marta A1 Ramón Vidal, Daniel A1 Santos Mazorra, Victoria Eugenia A1 Ladero Galán, Miguel A1 García-Ochoa Soria, Félix A1 Ripoll Morales, Vanessa AB 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.
