Abstract

The present invention relates to a process for the production of methyl methacrylate. The process of the present invention comprises the steps of: a) providing a microorganism in a fermentation medium, under conditions which said microorganism will produce a C3-C12 methacrylate ester; b) providing an organic phase in contact with the fermentation medium, said organic phase including C3-C12 methacrylate ester in a higher concentration than that in the fermentation medium; c) removing organic phase containing the said C3-C12 methacrylate ester from contact with the fermentation medium; and d) transesterifying the removed C3-C12 methacrylate ester with methanol, optionally after separation from the organic phase, to produce methyl methacrylate.
