Alternative Heterologous Expression of l‑Arabinose Isomerase from Enterococcus ...
Souza, Ticiane C. de; Oliveira, Ravena Casemiro; Bezerra, Saulo Gonçalves Santiago; Manzo, Ricardo M; Mammarella, Enrique J; Hissa, Denise CavalcanteThis study reports an alternative strategy for the expression of a recombinant l-AI from Enterococcus faecium DBFIQ E36 by auto-induction using glucose and glycerol as carbon sources and residual whey lactose as inducer agent. Commercial lactose and isopropyl β-d-1-thiogalactopyranoside (IPTG) were also evaluated as inducers for comparison of enzyme expression levels. The enzymatic extracts were purifed by afni...
Estudo das condições reacionais na produção de D-Tagatose catalisada por L-Arab...
Oliveira, Ravena CasemiroD-Tagatose is a rare sugar with a low caloric value, similar to sucrose, which has 92% of sweetness, but only 38% of the caloric value, approximately 1.5 kg.cal-1. It is considered an antihyperglycaemic agent, due to its low absorption and metabolism by the human organism. In addition, it has several benefits, such as its high antidiabetic potential for the treatment of type II diabetes and prebiotic effect. D-...
