Complete Genome Sequence of Lactobacillus acidophilus FSI4, Isolated from Yogurt

A new Lactobacillus acidophilus strain, FSI4, isolated from yogurt, was isolated and sequenced in our laboratory. Our data, although supportive of previous conclusions regarding the remarkable stability of L. acidophilus species, indicate accumulating mutations in commercial L. acidophilus strains that warrant further study of the effect of damaged genes on the competitiveness of these bacteria in gut microbiota.
