Acidipropionibacterium acidipropionici strain:WGS7 Genome sequencing. Acidipropionibacterium acidipropionici strain:WGS7

Propionic acid (PA) is used as a food preservative and increasingly, as a precursor for the synthesis of monomers. PA is produced mainly through hydrocarboxylation of ethylene, also known as the ‘oxo-process’; however, Propionibacterium species are promising biological PA producers natively producing PA as their main fermentation product. However, for fermentation to be competitive, a PA yield of at least 0.6 g/g is required. In this study, using genome shuffling, we obtained a strain capable of producing PA exceeding the commercial needs, Propionibacterium acidipropionici WGS7.
