d-Galacturonic acid is the main constituent of pectin, a naturally abundant compound. Pectin-rich residues accumulate when sugar is extracted from sugar beet or juices are produced from citrus fruits. It is a cheap raw material but currently mainly used as animal feed. Pectin has the potential to be an important raw material for biotechnological conversions to fuels or chemicals. In this paper, we review the microbial pathways for the catabolism of d-galacturonic acid that would be relevant for the microbial conversion to useful products.
