Abstract

The quantification of α-acetolactate (AAL) extracellular oxidative decarboxylation during an AAL overproducing strain culture shows that this reaction is at the origin of about 90% of the diacetyl production and that only a small proportion of extracellular AAL is readily transformed to diacetyl. These results, compared with previous ones obtained with a non AAL accumulating strain, allow research options to be put forward for the improvement of microbiological diacetyl production.
