Abstract:
1. A process for the fermentative production of an organic acid or a salt or derivative thereof, which process comprises incubating a bacterial strain, derived from the family Pasteurellaceae that comprises the 16S rDNA sequence of SEQ ID NO:1 or a sequence that is at least 96% to SEQ ID NO: 1 and wherein said strain is capable of utilizing glycerol as a carbon source for the fermentative production of succinic acid, wherein said strain is genetically modified so that it comprises a deregulation of its endogenous pyruvate-formate-lyase enzyme activity, and wherein said pyruvate-formate-lyase enzyme activity is decreased or “switched-off”, in a medium comprising an assimilable carbon source and cultivating said strain under conditions favouring the formation of the desired organic acid; and b) obtaining said organic acid or salt or derivative thereof from the medium.
