title: Taxonomic note "Lactobacillus pastorianus" (Van Laer, 1892) a former synonym for Lactobacillus paracollinoides.
abstract: "Lactobacillus pastorianus" (Van Laer, 1892) is not a validly described species and is not included in the Approved List of Bacterial Names. The strain is available in multiple culture collections as Lactobacillus sp. DSM 20197, L. brevis ATCC 8291, "L. pastorianus" CECT 5926, L. brevis JCM 1113, and "L. pastorianus" LMG 11990. Nearly identical 16S rRNA sequences and protein encoding genes for 6-phosphogluconate dehydrogenase (99.9%) revealed this strain as L. paracollinoides. A 16S-23S rRNA intergenic spacer region-based PCR assay did not differentiate "L. pastorianus" DSM 20197 from L. paracollinoides DSM 15502(T). Highly similar RAPD profiles differentiated both strains below species level.
