Lactic acid bacteria from 18 Spanish goat cheeses produced by seven dairies were isolated to evaluate the genetic diversity of this bacterial community. 136 representative isolates were characterized by phenotyping and Randomly Amplified Polymorphic DNA (RAPD-PCR) analysis. Ten species were identified with predominance of Lactobacillus paracasei subsp. paracasei. The presence of L. curvatus, L. pentosus, L. cellobiosus and L. rhamnosus has not hitherto been reported in Spanish goat cheeses. A high degree of genetic diversity was found for L. paracasei subsp. paracasei, L. curvatus and L. plantarum. Some of the identified strains displayed strong acidifying and proteolytic capacities.

UI MeSH Term Description Entries
D007778 Lactobacillus A genus of gram-positive, microaerophilic, rod-shaped bacteria occurring widely in nature. Its species are also part of the many normal flora of the mouth, intestinal tract, and vagina of many mammals, including humans. Lactobacillus species are homofermentative and ferment a broad spectrum of carbohydrates often host-adapted but do not ferment PENTOSES. Most members were previously assigned to the Lactobacillus delbrueckii group. Pathogenicity from this genus is rare.
D010641 Phenotype The outward appearance of the individual. It is the product of interactions between genes, and between the GENOTYPE and the environment. Phenotypes
