  • Title: Lactobacillus uvarum sp. nov.--a new lactic acid bacterium isolated from Spanish Bobal grape must.
    Author: Mañes-Lázaro R, Ferrer S, Rosselló-Mora R, Pardo I.
    Journal: Syst Appl Microbiol; 2008 Dec; 31(6-8):425-33. PubMed ID: 18930365.
    Abstract:
    Five strains isolated from grape musts in Spain in 1997, have been characterized by several molecular techniques, and three of them have been identified as pertaining to a new species. All strains are Gram-positive rods, aerotolerant and homofermentative bacteria that do not exhibit catalase activity. Phylogenetic analysis based on 16S rRNA gene sequences placed these strains within the genus Lactobacillus, closely related to Lactobacillus mali. DNA-DNA hybridization experiments confirmed that strain 71 belongs to the lately described species L. satsumensis, strain 88 belongs to L. mali and the other three isolates have an independent status at species level. Restriction analysis of the amplified 16S rRNA gene (16S-ARDRA), internal spacer region (ISR) analysis, random amplified polymorphism DNA (RAPD) and ribotyping were performed in order to establish genotypic similarities and differences between the new species and their closest species. The three isolates can be genetically differentiated from their closest relatives by RAPD analysis and ribotyping. Phenotypically, they can be distinguished by several traits such as their ability to grow at pH 3.3 and NaCl 5% (w/v) and by certain carbohydrate fermentations. The name L. uvarum sp. nov. is proposed. The type strain is 8T (=DSM 19971T = colección española de cultivos tipo (CECT) 7335T).
