One hundred and seventy-eight lactobacilli isolated from wine were characterized by a polyphasic approach. Strains were phenotypically identified at genus and species level by classical tests including the analysis of cell morphology, homo/heterofermentative character, sugar fermentation patterns, growth at different temperatures and the optical nature of the isomer of lactic acid produced from glucose. Molecular techniques such as random amplification of polymorphic DNA (RAPD), amplified 16S rDNA restriction analysis (16S-ARDRA), PFGE-RFLP and ribotyping were used to characterize strains, and their potential for identification and/or typing was evaluated. The information obtained with these techniques was processed with the BioNumerics software in order to analyse relationships existing between isolated strains and various reference species of the genus. Then, taxonomic dendrograms were obtained, and this information allowed the proposal of molecular procedures suitable for the identification and typing of these wine micro-organisms. The techniques useful for both identification and typing were RAPD and ribotyping, while 16S-ARDRA was only useful for identification and PFGE-RFLP only for typing purposes. The wine strains were identified as Lactobacillus brevis (19 strains), Lactobacillus collinoides (2 strains), Lactobacillus hilgardii (71 strains), Lactobacillus paracasei (13 strains), Lactobacillus pentosus (2 strains), Lactobacillus plantarum (34 strains) and Lactobacillus mali (10 strains).

“…In an accompanying Request for an Opinion (Dellaglio et al, 2002), we propose that the Judicial Commission consider that the strain ATCC 393 T is scientifically unsuitable as the type strain of the species L. casei. For strains belonging to the same taxon as strain ATCC 334 and NCDO 151, the species name L. casei has to be retained on the basis of its priority over L. paracasei.…”

T form a single phylogenetic group. The taxonomic status of species and strains at issue is discussed. Keywords : Lactobacillus casei, recA, taxonomyLactobacillus casei and related species include phenotypically and genetically heterogeneous strains able to colonize various natural and man-made environments (Vescovo et al., 1995). Many strains are currently employed as probiotics or mixed cultures for dairy products. Despite its importance for the food industry, the taxonomy of the L. casei group is still unclear. Historically, the systematics of the L. casei group have been problematic and adjustments have been introduced based on new taxonomic methods that have gradually become available. Initially, Hansen & Lessel (1971) designated strain ATCC 393 T as the type strain of L. casei subsp. casei on the basis of a few phenotypic traits. However, Dellaglio et al. (1975) (Dellaglio et al., 1991). The proposal was denied (Wayne, 1994). Dicks et al. (1996) Nour (1998) proposed that 16S-23S and 23S-5S intergenic spacer region sequences might represent a useful alternative to 16S and 23S rDNA for establishing the phylogeny of closely related bacterial species, because of the higher sequence and fragment length polymorphism. Comparative analysis of the 23S-5S rRNA intergenic spacer regions of L. caseirelated strains was performed by Chen et al. (2000). Their observations supported the request of Dellaglio et al. (1991) to replace strain ATCC 393 T with strain ATCC 334 as the neotype of L. casei subsp. casei.

“…As a consequence, it was proposed to create a new species for these isolates, Lactobacillus paracasei (Collins et al, 1989). It was also proposed that Lactobacillus casei ATCC 334 and Lactobacillus paracasei strains were members of the same taxon and therefore could be united within the name Lactobacillus casei, the name Lactobacillus paracasei being rejected, and designating ATCC 334 as the neotype strain for the species Lactobacillus casei (Dellaglio et al, 2002).…”
