Abstract
The inability of two Lactobacillus strains to ferment D-xylose was complemented by the introduction of Lactobacillus pentosus genes encoding D-xylose isomerase, D-xylulose kinase, and a D-xylose catabolism regulatory protein. This result opens the possibility of using D-xylose fermentation as a food-grade selection marker for Lactobacillus spp.
