WebJun 30, 2016 · Background 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. By contrast, AIs from … Webl-Arabinose isomerase (EC 5.3.1.4, l-AI) mainly catalyzes the reversible aldose–ketose isomerization between l-arabinose and l-ribulose. l-AIs can also catalyze other reactions, such as the conversion of d-galactose to d-tagatose.In this study, the araA gene encoding l-AI was PCR-cloned from Thermoanaerobacterium saccharolyticum NTOU1 and then …
WebThe production of L-AI by these LAB allowed the bioconversion of D-galactose to D-tagatose during fermentation in laboratory media and milk. We also established that the addition of L-AI to milk also allowed the conversion of D-galactose into D-tagatose during the fermentation process.
