Indução da fermentação maloláctica em vinho tinto com a cultura láctica viniflora oenos Induction of malolactic fermentation in red wine with the starter culture viniflora oenos [PDF]
Ciência Rural, 1997 A fermentação maloláctica é responsável pela redução da acidez total, muitas vezes elevada em vinhos tintos jovens, ao mesmo tempo que proporciona maior estabilidade biológica e complexidade de aroma e sabor. No Estado do Rio Grande do Sul, a fermentação

Uniport of Monoanionic L‐malate in Membrane Vesicles from Leuconostoc Oenos [PDF]
European Journal of Biochemistry, 1994 L‐malate transport was studied in membrane vesicles from Leuconostoc oenos MLE(–) (mutant lacking malolactic enzyme) which were fused with liposomes containing beef heart cytochrome c oxidase as a proton‐motive‐force‐generating system. In these hybrid membranes, accumulation of L‐malate was observed in response to a pH gradient (pH), with the inside ...

Cloning and characterization of the genes encoding the malolactic enzyme and the malate permease of Leuconostoc oenos. [PDF]
Appl Environ Microbiol, 1996 Using degenerated primers from conserved regions of the protein sequences of malic enzymes, we amplified a 324-bp DNA fragment by PCR from Leuconostoc oenos and used this fragment as a probe for screening a Leuconostoc oenos genomic bank.

Genetic organization of the mle locus and identification of a mleR-like gene from Leuconostoc oenos. [PDF]
Appl Environ Microbiol, 1996 Characterization of the mle locus harboring the malolactic enzyme gene mleA and malate permease gene mleP from Leuconostoc oenos was completed in this study by mRNA analysis.

Uniport of anionic citrate and proton consumption in citrate metabolism generates a proton motive force in Leuconostoc oenos. [PDF]
J Bacteriol, 1994 The mechanism and energetics of citrate transport in Leuconostoc oenos were investigated. Resting cells of L. oenos generate both a membrane potential (Delta Psi) and a pH gradient (Delta pH) upon addition of citrate.

Application of C Nuclear Magnetic Resonance To Elucidate the Unexpected Biosynthesis of Erythritol by Leuconostoc oenos. [PDF]
Appl Environ Microbiol, 1992 Natural-abundance C nuclear magnetic resonance (C-NMR) revealed the production of erythritol and glycerol by nongrowing cells of Leuconostoc oenos metabolizing glucose.

Lysogeny in Leuconostoc oenos [PDF]
Journal of General Microbiology, 1991 Thirty strains of Leuconostoc oenos were exposed to mitomycin C to induce lysogenic bacteriophages. Lysis curves typical for lysogenic strains were obtained with 19 strains. Indicator strans were found for 17 of these phages. Five were characterized by electron microscopy, lytic spectrum, molecular masses of the proteins, sequencing of five N-terminal ...

Molecular characterization of the gene encoding an 18-kilodalton small heat shock protein associated with the membrane of Leuconostoc oenos. [PDF]
Appl Environ Microbiol, 1997 In Leuconostoc oenos, different stresses such as heat, ethanol, and acid shocks dramatically induce the expression of an 18-kDa small heat shock protein called Lo 18. The corresponding gene (hsp18) was cloned from a genomic library of L.

CIDER PRODUCTION WITH IMMOBILIZEDLEUCONOSTOC OENOS [PDF]
Journal of the Institute of Brewing, 1998 Cider obtained with Saccharomyces earevlaiae and immobilized Leuconoatoc oenos attained the desired attenuation without residual sugars. Decarboxyiation off L-malic to L-lactic acid by heteroiactic bacteria and the formation off secondary products in cider were studied using immobilized cells of L oenos IC11. Malic acid metabolism was influenced by the

Quantitative study of interactions between Saccharomyces cerevisiae and Oenococcus oeni strains [PDF]
, 2008 This study examines the interactions that occur between Saccharomyces cerevisiae and Oenococcus oeni strains during the process of winemaking. Various yeast/bacteria pairs were studied by applying a sequential fermentation strategy which simulated the ...
