Abstract

See full text

Diols produced in fermentation are processed in broth by esterification of the product diol with a carboxylic acid (e.g., fatty acid) and a catalyst (e.g., lipase) capable of esterifying the product diol, such as 1,3-propanediol, with the carboxylic acid to form the diol esters. The diol esters can be extracted from the broth, and the product diol recovered from the diol esters. The carboxylic acid can also serve as an extractant for removal of the diol esters from the fermentation medium.
