Concentrated Cultures of Leuconostoc citrovorum

Cell wall constituents of Leuconostoc citrovorum and Leuconostoc mesenteroides.

The cell wall constituents of Leuconostoc citrovorum 8082, L. mesenteroides 10830a, and L. mesenteroides 11449 have been ascertained. All three strains contained glycerol. Glucose and rhamnose were the major reducing sugar constituents. Alanine, glutamic acid, lysine, glucosamine, and muramic acid were the principal amino acids and amino sugars in all three strains. In addition, strain 10830a c...

Media for Leuconostoc mesenteroides P-60 and Leuconostoc citrovorum 8081.

In the routine use of typical media for the microbiological determination of the sixteen amino acids standard curves have accumulated which reveal the amounts of each amino acid required for the growth of the assay organism when all other amino acids are present in excess. Thus it was observed that the relative amounts of the various amino acids needed by Leuconostoc mesenteroides P-60 did not ...

Synthesis of citrovorum factor by Leuconostoc citrovorum; potentiation by ascorbic acid.

Further studies on the factor required by Leuconostoc citrovorum 8081.

Recently it was noted that Leuconostoc citrovorum 8081 failed to grow on a synthetic medium unless supplied with certain preparations from liver or other crude materials (1). Commercial preparations useful against pernicious anemia proved to be particularly active for this strain of L. citrovorum. The present report deals with preliminary attempts to concentrate the active principle and to diff...

Some factors influencing carbon dioxide production by Leuconostoc citrovorum.

This study was undertaken to determine whether Leuconostoc citrovorum plays a role in carbon dioxide production in milk. The ability of L. citrovorum strains to produce gas was studied by two methods. A qualitative method, in which an agar plug was forced up the neck of a volumetric flask, measured gas visually. This method demonstrated that 0.25% yeast extract, in a milk medium at 30 C, stimul...
