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...
متن کاملMedia 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 ...
متن کاملBranched-Chain Amino Acid Transport in Cytoplasmic Membranes of Leuconostoc mesenteroides subsp. dextranicum CNRZ 1273.
Membrane vesicles of Leuconostoc mesenteroides subsp. dextranicum fused with proteoliposomes prepared from Escherichia coli phospholipids containing beef heart cytochrome c oxidase were used to study the transport of branched-chain amino acids in a strain isolated from a raw milk cheese. At a medium pH of 6.0, oxidation of an electron donor system comprising ascorbate, N,N,N',N'-tetramethyl-p-p...
متن کاملThe nutritional requirements of Leuconostoc dextranicum for growth and dextran synthesis.
The recent literature contains numerous references to the use of partially hydrolyzed dextrans as plasma substitutes (Bull et al., 1949; Thorsen, 1949). Because of this interest, and as part of a general study of bacterial polysaccharide synthesis, the nutritional requirements of the major dextran forming organisms, Leuconostoc mesenteroides and L. dextranicum, are being investigated (Whiteside...
