Characterization of an L-arabinose isomerase from Bacillus coagulans NL01 and its application for D-tagatose production

L-arabinose isomerase (AI) is a crucial catalyst for the biotransformation of D-galactose to D-tagatose. In previous reports, AIs from thermophilic bacterial strains had been wildly researched, but the browning reaction and by-products formed at high temperatures restricted their applications.
