Genetic diversity (RAPD-PCR) of lactobacilli isolated from ?Almagro? eggplant fermentations from two seasons

Abstract

Genetic diversity of 323 strains of lactobacilli isolated from an Almagro eggplant manufacturing plant was analyzed by using random amplified polymorphic DNA (RAPD). Thirty-four distinct RAPD patterns were obtained with 95% of isolates grouped into 18 main clusters. Genetic diversity was higher in brines from season II, Lactobacillus plantarum and Lactobacillus fermentum/cellobiosus being the species with the greatest number of genotypes. A single L. fermentum/cellobiosus genotype comprised isolates from both seasons and could be considered endemic to that factory.
