Expanding the biotechnology potential of lactobacilli through comparative genomics of 213 strains and associated genera.
PMID : 26415554 DOI : 10.1038/ncomms9322 PMC : PMC4667430 DOI : 10.1038/ncomms9322 PMC : PMC4667430
Lactobacilli are a diverse group of species that occupy diverse nutrient-rich niches associated with humans, animals, plants and food. They are used widely in biotechnology and food preservation, and are being explored as therapeutics. Exploiting lactobacilli has been complicated by metabolic diversity, unclear species identity and uncertain relationships between them and other commercially important lactic acid bacteria. The capacity for biotransformations catalysed by lactobacilli is an untapped biotechnology resource. Here we report the genome sequences of 213 Lactobacillus strains and associated genera, and their encoded genetic catalogue for modifying carbohydrates and proteins. In addition, we describe broad and diverse presence of novel CRISPR-Cas immune systems in lactobacilli that may be exploited for genome editing. We rationalize the phylogenomic distribution of host interaction factors and bacteriocins that affect their natural and industrial environments, and mechanisms to withstand stress during technological processes. We present a robust phylogenomic framework of existing species and for classifying new species.

The type strain of Lactobacillus casei is ATCC 393, ATCC 334 cannot serve as the type because it represents a different taxon, the name Lactobacillus paracasei and its subspecies names are not rejected and the revival of the name 'Lactobacillus zeae' contravenes Rules 51b (1) and (2) of the International Code of Nomenclature of Bacteria. Opinion 82.
PMID : 18599731 DOI : 10.1099/ijs.0.2008/005330-0
The Judicial Commission affirms that typification of Lactobacillus casei is based on ATCC 393, that ATCC 334 is a member of a different taxon and that the publication rejecting the name Lactobacillus paracasei (and its included subspecies) together with the revival of the name 'Lactobacillus zeae' contravenes Rules 51b (1) and (2) of the International Code of Nomenclature of Bacteria.

Comparative sequence analyses of the genes coding for 16S rRNA of Lactobacillus casei-related taxa.
PMID : 8995801 DOI : 10.1099/00207713-47-1-54
The primary structures of the 16S rRNA genes of the type strains of Lactobacillus casei and related taxa were determined by PCR DNA-sequencing methods. The sequences of Lactobacillus casei, Lactobacillus zeae, Lactobacillus paracasei, and Lactobacillus rhamnosus were different. The Knuc values ranged from 0.0040 to 0.0126. On the basis of the Knuc values and the levels of DNA-DNA relatedness among the strains of these species, the L. casei-related taxa should be classified in the following three species: L. zeae, which includes the type strains of L. zeae and L. casei; a species that includes the strains of L. paracasei and L. casei ATCC 334; and L. rhamnosus.
|52365||The genome sequence of L. casei type strain DSM 20011 (accession AZCO01000000) does not match that of type strain JCM 1134 (accession BALS01000000) or of type strain ATCC 393 (accession AP012544). It is more similar to those of L. paracasei subps. paracasei type strain ATCC 25302 (accession ACGY01000000) and L. paracasei subsp. tolerans type strain DSM 20258 (accession AYYJ01000000).||9246||

The status of the species Lactobacillus casei (Orla-Jensen 1916) Hansen and Lessel 1971 and Lactobacillus paracasei Collins et al. 1989. Request for an opinion.

On the basis of considerable published evidence, it is concluded that the species Lactobacillus casei is not correctly represented by the strain actually designated as the type strain ATCC 393. It is proposed that the Judicial Commission consider: (1) that ATCC 393T is scientifically unsuitable as the type strain of Lactobacillus casei and should be reclassified as Lactobacillus zeae; (2) that Lactobacillus casei ATCC 334 and Lactobacillus paracasei strains are members of the same taxon and therefore can be united within the name Lactobacillus casei (Rules 42 and 23a), the name Lactobacillus paracasei being rejected; and (3) designating ATCC 334 as the neotype strain for the species

Comparative sequence analysis of a recA gene fragment brings new evidence for a change in the taxonomy of the Lactobacillus casei group.
PMID : 11760954 DOI : 10.1099/00207713-51-6-2113 DOI : 10.1099/00207713-51-6-2113
The taxonomic positions of species of the Lactobacillus casei group have been evaluated by sequencing and phylogenetic analysis of a 277 bp recA gene fragment. High sequence similarity between strain ATCC 393T, currently designated as the type strain of L. casei, and the type strain of Lactobacillus zeae, LMG 17315T, has been established, while L. casei ATCC 334 and Lactobacillus paracasei NCDO 151T form a single phylogenetic group. The taxonomic status of species and strains at issue is discussed.

Comparative analysis of the genes encoding 23S-5S rRNA intergenic spacer regions of Lactobacillus casei-related strains.
PMID : 10758849 DOI : 10.1099/00207713-50-2-471
In this study, investigations into the 23S-5S rRNA intergenic spacer regions (ISRs) of the Lactobacillus casei group were performed. A 1.6 kb fragment, from Lactobacillus paracasei strain ATCC 27092, containing part of the 5S rRNA gene (60 bp), the 5S-23S spacer region (198 bp) and part of the 23S rRNA gene (1295 bp) was cloned and sequenced (GenBank no. AF098107). This fragment was used as a probe to determine the rRNA restriction fragment length polymorphism (RFLP) patterns of nine strains belonging to the Lactobacillus casei group, along with four other non-Lactobacillus casei lactobacilli species. A pair of PCR primers, 23-Fl and 5-Ru, was designed and used for PCR amplification of the 23S-5S rRNA ISRs of these strains. The ISR length and sequence polymorphisms provided additional information for the taxonomic study of the Lactobacillus casei group. The spacer-length polymorphism of Lactobacillus rhamnosus was distinct from those of the other strains and this observation is consistent with the classification of Lactobacillus rhamnosus proposed by Mori et al. For all Lactobacillus casei and Lactobacillus paracasei strains, two major bands (approx. 250 and 170 bp in size) were obtained except in the case of Lactobacillus paracasei subsp. tolerans strain NCIMB 9709T, which yielded only one amplified product (250 bp). The sequencing data of the PCR products of seven well-characterized Lactobacillus casei and Lactobacillus paracasei strains revealed the presence of a 76/80 bp insertion/deletion with some random, single-base substitutions between the longer and shorter spacers for each respective strain. A few base variations were also detected within different strains in this group although the overall sequence similarity was very high (95.9-99.5%). The rRNA RFLP and the spacer sequence of Lactobacillus casei type strain ATCC 393T exhibited unique identities in this cluster. On the other hand, Lactobacillus casei strain ATCC 334 showed a high level of similarity with the other Lactobacillus casei strains tested. These observations lend some support to the request for the reassignment of strain ATCC 334 as the neotype of Lactobacillus casei subsp. casei in place of strain ATCC 393T.

Reclassification of Lactobacillus casei subsp. casei ATCC 393 and Lactobacillus rhamnosus ATCC 15820 as Lactobacillus zeae nom. rev., designation of ATCC 334 as the neotype of L. casei subsp. casei, and rejection of the name Lactobacillus paracasei.
PMID : 8573516 DOI : 10.1099/00207713-46-1-337
The type strain of Lactobacillus casei subsp. casei (ATCC 393) exhibits low levels of DNA homology with other strains of L. casei subsp. casei (8 to 46%) and strains of Lactobacillus paracasei (30 to 50%), but exhibits a level of DNA similarity of 80% with Lactobacillus rhamnosus ATCC 15820, the original type strain of "Lactobacterium zeae" Kuznetsov 1959. Strains ATCC 393T (T = type strain) and ATCC 15820T are members of one protein profile cluster that is separate from the other Lactobacillus spp. The randomly amplified polymorphic DNA PCR profile of strain ATCC 393T is also different from the profiles obtained for the other species. L. casei ATCC 334T is genetically closely related to L. casei subsp. casei strains (71 to 97%) and L. paracasei strains (71 to 91%), is a member of the same protein profile cluster as these organisms, and shares several DNA amplicons with L. paracasei strains. On the basis of these results, we propose that L. casei subsp. casei ATCC 393T and L. rhamnosus ATCC 15820 should be reclassified as members of Lactobacillus zeae nom. rev. (type strain, ATCC 15820), that strain ATCC 334 should be designated the neotype strain of L. casei subsp. casei, and that the name L. paracasei should be rejected.
