摘要

BACKGROUNDOne of the most popular methods of glycerol utilisation involves its bioconversion to low-molecular organic compounds such as polyoles or organic acids. Because of the presence of contaminants in the post-fermentation broth, including left-over glycerol, small amounts of proteins, inorganic salts and some organic acids formed in the process of fermentation (mainly acetate, formic and lactic acids), the success of bioconversion is determined by the process of purification. In the study presented the usefulness of nanofiltration with the use of ceramic membranes for concentration and separation of fumaric acid from glycerol was evaluated.
