Genotypic characterization of L.sanfranciscensis strains by optimized MLST and PFGE.
MLST scheme has been re-designed with four genes.
mapA and pgmA genes were not considered as housekeeping genes.
Lactobacillus sanfranciscensis strains with various genotypes coexist within sourdough.
Higher diversity between sourdough than within sourdough was shown.
