Enzymatic Production of Trehalose and Trehalulose by Immobilized Thermostable Trehalose Synthase

Abstract

Trehalose, a versatile disaccharide renowned for its unique physical and chemical properties, finds extensive application in the food, pharmaceutical, and cosmetic industries. While conventional extraction methods face challenges, enzymatic conversion offers a promising avenue for the industrial production of trehalose. This study delves into a novel synthetic approach utilizing a recombinant enzyme, merging the thermostable trehalose synthase domain from Thermus thermophiles with a cellulose binding domain. Immobilization of this enzyme on cellulose matrices enhances stability and facilitates product purification, opening avenues for efficient enzymatic synthesis. Notably, the engineered enzyme demonstrates additional activity, converting sucrose into trehalulose. This dual functionality, combined with immobilization strategies, holds immense potential for scalable and cost-effective production of trehalose and trehalulose, offering promising prospects in various industrial and biomedical applications.
