RELATION OF LEUCONOSTOC CITROVORUM FACTOR TO ACTIVITY OF LIVER CHOLINE OXIDASE

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...

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

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...

Observations on a growth factor for Leuconostoc citrovorum.

3. The relative amount of the phospholipin in the two cell types was similar, but the distribution ofthe individual phospholipins was different. The red cells contained more kephalin and the polymorphonuclear leucocytes contained more sphingomyelin. This work was supported by grants from the National Research Council and National Cancer Institute of Canada. Thanks are due to Miss Ann Boyce and ...
