Abstract:
:A total of 248 strains of predominant lactobacilli isolated during the manufacture and ripening of artisanal Manchego cheeses obtained from two dairies were obtained and the genetic diversity of 197 investigated using random amplified polymorphic DNA (RAPD-PCR). 51 isolates could not be lysed and were therefore not genotyped. Forty-two distinct RAPD patterns, grouped in six major clusters at a similarity level of 54%, were obtained. Phenotypic characterization of isolates enabled their assignment to the species L. plantarum, L. brevis, L. paracasei subsp. paracasei, L. fermentum, L. pentosus, L. acidophilus and L. curvatus. In samples from both dairies, the species L. plantarum, L. brevis and L. paracasei subsp. paracasei dominated during ripening. Three genotypes showed excellent physiological characteristics and were therefore proposed as adjunct cultures for Manchego cheese manufacture.
