The disclosure is directed to a method and a system for recovering at least one organic product from fermentation broth. The disclosure relates to the use of liquid-liquid extraction and/or distillation to recover at least one organic product from a fermentation broth. In an embodiment, the recovery of the product is completed in a manner that minimizes stress on the microbial biomass, such that it remains viable, at least in part, and may be recycled and reused in the fermentation process, with minimal water extraction which results in increased efficiency in the fermentation process.

The invention relates to a process for preparing carboxylic acids or salts thereof by hydrolysis or saponification of an ester, which is obtained by alkoxycarbonylation of a C2 to C20 hydrocarbon having at least one multiple bond, preferably having at least one olefinic double bond, in which the homogeneous catalyst system used is separated from the product mixture by means of membrane separation. In a development of the present invention, the ester thus formed is converted into another ester by transesterification and then hydrolyzed or saponified.
