WebThe main reaction catalyzed by L-AI is the bioconversion of L-arabinose into L-ribulose, however, it also promotes efficiently the isomerization of D-galactose to D-tagatose . In fact, most of the publications on the enzymatic synthesis of D-tagatose use L-AI as biocatalyst [ 22 , 23 , 24 ]. 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 …
WebUnder the optimal conditions, the robust spores can convert 75% d-galactose (100 g/L) into d-tagatose after 24 h, and the conversion rate remained at 56% at the third cycle. Therefore, this biocatalysis system, which could express the target enzyme on the food-grade vector, was an alternative method for the value-added production of d-tagatose. WebSubsequent bioconversion of D-Galactose into D-tagatose with the purified BAAI provided 56.7% conversion efficiency after 10 h at 55°C, which is excellently comparable …
