food industry

Corynebacterium glutamicum

trehalose has many potential applications in biotechnology and the food industry due to its protective effect against environmental stress. Raising trehalose productivity can be achieved through homologous overexpression of maltooligosyltrehalose synthase and maltooligosyltrehalose trehalohydrolase. Overexpression of the treY gene and the treY/treZ synthetic operon significantly increases maltooligosyltrehalose synthase activity, the rate-limiting step, and improves the specific productivity and the final titer of trehalose. Furthermore, a strong decrease is noted in glycogen accumulation. Expression of galU/treY and galU/treYZ synthetic operons show a partial recovery in the intracellular glycogen levels and a significant improvement in both intra- and extracellular trehalose content
