Development of an enzymatic process for the production of lactobionic acid.
Abstract
Lactose is a cheap, renewable raw material which accumulates in vast amounts in whey. However, it can serve as an attractive starting material for various products that value-added products. By specific oxidation of this disaccharide lactobionic acid can be obtained which is attractive for both food technological and pharmaceutical applications. We found that the enzyme cellobiose dehydrogenase (CDH) is a suitable and efficient catalyst for the oxidation of lactose to lactobionic acid. During the oxidation of lactose by CDH electrons are transferred to artificial electron acceptors (certain dyes) but also to metal ions. For the efficient utilization of CDH in an enzymatic process suitable strategies of continuously regenerating the electron acceptor are investigated.
