Identification of Lactobacillus UFV H2b20 (probiotic strain) using DNA-DNA hybridization

Sequence analyses of the 16S rDNA gene and DNA-DNA hybridization tests were performed for identification of the species of the probiotic Lactobacillus UFV H2b20 strain. Using these two tests, we concluded that this strain, originally considered Lact. acidophilus, should be classified as Lact. delbrueckii.

Análise da seqüência do gene 16S rDNA e ensaios de hibridização DNA_DNA foram empregados para identificar a espécie da cepa probiótica Lactobacillus UFV H2b20. Empregando-se estes dois testes, concluímos que esta cepa, originalmente considerada Lact. acidophilus, deve ser classificada como Lact. delbrueckii.
