GTF CELLS, VECTORS AND SEQUENCES AND APPLICATIONS THEREOF IN THE FOOD SECTOR

摘要

The invention relates to GTF micro-organisms, vectors and sequences which are formed by or comprise gene gtf de P.damnosus 2.6 which encodes a glycosyltransferase that is located in the membrane and which enables the production of exopolysaccharides of the -glucan type by overexpression of said recombinant gene. The fact that only one gene is involved in the synthesis of the aforementioned enzyme facilitates the optimisation of the expression conditions which enable the production of -glucans on an industrial scale. Said polymers, which can be used as additives in numerous foods, also have properties that are beneficial to human health. Moreover, said transformed GTF micro-organisms can be used in processes for the fermentation of foods, such as dairy products, alcoholic drinks and oats.
