Occurrence and properties of bacteriophages of Leuconostoc oenos in Australian wines [PDF]
Bacteriophages specific for Leuconostoc oenos were isolated from four red wines undergoing malolactic fermentation in one winery. Bacteriophages were not found in samples of 16 other wines. The morphology of the phages was examined by electron microscopy. The phages did not lyse all strains of L. oenos, and susceptibility correlated to some extent with

Pathway and regulation of erythritol formation in Leuconostoc oenos. [PDF]
It was recently observed that Leuconostoc oenos GM, a wine lactic acid bacterium, produced erythritol anaerobically from glucose but not from fructose or ribose and that this production was almost absent in the presence of O2. In this study, the pathway of formation of erythritol from glucose in L.

Taxonomic characterization ofLeuconostoc mesenteroidesandLeuconostoc oenosbacteriophage [PDF]
Nineteen Leuconostoc mesenteroides phage isolated during natural coffee fermentation or from dairy products were compared. DNA-DNA hybridization, morphology and composition of major structural proteins revealed the existence of six genetic groups, four containing only one phage. The majority of the phage (twelve) belong to a unique group represented by

Production of Leuconostoc oenos Biomass under pH Control. [PDF]
Leuconostoc oenos was grown on apple juice-based media. The effect of pH control on metabolism and biomass production was studied. Without pH control, L. oenos acidified the apple juice media to approximately pH 3.6.

In vitro reassembly of the malolactic fermentation pathway of Leuconostoc oenos (Oenococcus oeni). [PDF]
The mechanism of metabolic energy generation by malolactic fermentation was studied with artificial membrane vesicles of Leuconostoc oenos (Oenococcus oeni). (Note that although L. oenos was recently reclassified as O. oeni [L. M. T. Dicks, F. Dellaglio, and M. D. Collins, Int. J. Syst. Bacteriol.

Biochemical basis for glucose-induced inhibition of malolactic fermentation in Leuconostoc oenos. [PDF]
The sugar-induced inhibition of malolactic fermentation in cell suspensions of Leuconostoc oenos, recently reclassified as Oenococcus oeni (L. M. T. Dicks, F. Dellaglio, and M. D. Collins, Int. J. Syst. Bacteriol. 45:395-397, 1995) was investigated by in vivo and in vitro nuclear magnetic resonance (NMR) spectroscopy and manometric techniques. At 2 mM,

Leuconostoc oenos sp.nov. [PDF]
SUMMARY: Nineteen strains of Gram-positive cocci isolated from wine and belonging to the genus Leuconostoc were examined and are considered to form a new species which is named Leuconostoc oenos. These strains differ from other leuconostocs because they grow better in a medium containing tomato juice than in yeast glucose citrate broth normally used in

Growth and energetics of Leuconostoc oenos during cometabolism of glucose with citrate or fructose. [PDF]
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.

The proton motive force generated in Leuconostoc oenos by L-malate fermentation. [PDF]
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.
