Cell wall constituents of Leuconostoc citrovorum and Leuconostoc mesenteroides.

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 ...

The effect of folic acid upon the urinary excretion of the growth factor required by Leuconostoc citrovorum.

In a previous study it was observed that Leuconostoc citrovorum 8081 failed to grow on a synthetic medium adequate for the growth of Leuconostoc mesenteroides P-60 and other common assay organisms (1). However, the addition to the medium of certain extracts from liver permitted excellent growth of L. citrovorum. Similarly, folic acid stimulated growth of the organism but the amounts necessary w...

Characterization of Glucansucrases and Fructansucrases Produced by Wild Strains Leuconostoc Mesenteroides Ure13 and Leuconostoc Mesenteroides Lm17 Grown on Glucose or Fructose Medium as a Sole Carbon Source

A study on the production of soluble and cell wall-bound glucansucrases (GS) and fructansucrases (FS) by Leuconostoc mesenteroides URE13 and L. mesenteroides Lm17 during their growth on media containing sucrose, glucose or fructose as a main carbon source was carried out. The changes in the enzyme activity, the assimilation of sugars and the formation of metabolites during the cultivation were ...

Characterization of the Dextran Produced by Leuconostoc mesenteroides from Date Fruit Extract

In the present study, the production of dextran from date extract and sucrose as carbon sources by the bacterium Leuconostoc mesenteroides NRRL B512 (f) was investigated. In comparison to blue dextran (Mw≈2000 Da), dextran molecular weight was reduced (Mw2000 KDa). Flow behavior indices of dextran solutions from date extracts were investigated and rheological parameters were evaluated at concen...
