Characterization of Leuconostoc oenos Isolated from Oregon Wines. [PDF]
Appl Environ Microbiol, 1985 This study was designed to characterize isolates of Leuconostoc species from Oregon wines. Gram-positive cocci were isolated, and their biochemical properties and abilities to decompose malic acid were determined.

The proton motive force generated in Leuconostoc oenos by L-malate fermentation. [PDF]
J Bacteriol, 1996 In cells of Leuconostoc oenos, the fermentation of L-malic acid generates both a transmembrane pH gradient, inside alkaline, and an electrical potential gradient, inside negative. In resting cells, the proton motive force ranged from -170 mV to -88 mV between pH 3.1 and 5.6 in the presence Of L-malate.

Growth and energetics of Leuconostoc oenos during cometabolism of glucose with citrate or fructose. [PDF]
Appl Environ Microbiol, 1994 The metabolic and energetic characterization of the growth of Leuconostoc oenos on glucose-citrate or glucose-fructose mixtures enables the potential role of this bacterium in the wine-making process to be ascertained. Moreover, mixotrophic conditions remain a suitable means for improving biomass productivities of malolactic starter cultures.

Comparison of Leuconostoc oenos Strains by Pulsed-Field Gel Electrophoresis. [PDF]
Appl Environ Microbiol, 1993 Pulsed-field gel electrophoresis of chromosomal DNA digested with Not I or Sfi I was used to differentiate individual strains of Leuconostoc oenos. L. oenos isolates with 13 different restriction digest patterns were detected in New Zealand wines undergoing malolactic ...

Enzyme Basis for pH Regulation of Citrate and Pyruvate Metabolism by Leuconostoc oenos. [PDF]
Appl Environ Microbiol, 1995 Citrate and pyruvate metabolism by nongrowing cells of Leuconostoc oenos was investigated. (sup13)C nuclear magnetic resonance (NMR) spectroscopy was used to elucidate the pathway of citrate breakdown and to probe citrate or pyruvate utilization, noninvasively, in living cell suspensions.

Leuconostoc oenos and malolactic fermentation in wine: a review
Journal of Industrial Microbiology and Biotechnology, 1999 This review article summarizes the state of the art on Leuconostoc oenos, the bacteria responsible for malolactic fermentation in wine. Both basic and practical aspects related to the metabolism of this microorganism and malolactic fermentation in general are critically reviewed.

The Growth Factor and Amino Acid Requirements of Species of the Genus Leuconostoc, including Leuconostoc paramesenteroides (sp.nov.) and Leuconostoc oenos [PDF]
Journal of General Microbiology, 1967 SUMMARY: The vitamin requirements of 63 strains and the amino acid requirements of 40 strains belonging to the genus Leuconostoc have been determined. The amino acid requirements separate the genus into dextran and non-dextran formers and in particular indicated that non-dextran formers should be excluded from Leuconostoc mesenteroides.

Medium for Screening Leuconostoc oenos Strains Defective in Malolactic Fermentation. [PDF]
Appl Environ Microbiol, 1989 A new sensitive medium was developed to screen and isolate mutagenic Leuconostoc oenos strains defective in malolactic fermentation. The essential components of the medium included fructose (22 mM), l -malic acid (74.6 mM), bromocresol green (as pH indicator), and cellulose powder.

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 ...
