O'Barr, Thomas P. (Agricultural Research Service, Washington, D.C.). Effect of alanine and threonine on the synthesis of serine by Leuconostoc mesenteroides. J. Bacteriol. 86:1321-1325. 1963.-Growth of Leuconostoc mesenteroides in the absence of serine was inhibited by l-alanine and l-threonine. Varying the glycine concentration when l-alanine was present suggested a direct relationship between...

Lynch, Judith L. (Northwestern University, Evanston, Ill.), and Francis C. Neuhaus. On the mechanism of action of the antibiotic O-carbamyl-d-serine in Streptococcus faecalis. J. Bacteriol. 91:449-460. 1966.-The antibiotic O-carbamyl-d-serine, an analogue of d-alanine, is an inhibitor of bacterial cell-wall biosynthesis. Growth of Streptococcus faecalis R in the presence of O-carbamyl-d-serine ...

EPR spectra of alanine dosimeters irradiated by gamma-rays and alpha-particles were measured at different microwave power. The decomposed into three components corresponding to stable radiation-induced radicals. Different ratio the was obtained for gamma- alpha-irradiated alanine. observed effect can be used discrimination contribution alpha- gamma-radiation in mixed radiation field. That may u...

The L-alanine family crystals such as pure L-Alanine, hydrochloride (HCl) mixed Lalanine, potassiumchloride (kcl) mixed l-alanine and potassium dihydrogen phosphate (kdp) mixed l-alanine have been successfully grown from the aqueous solution by slow evaporation method at room temperature. The grown crystals FT-IR spectral studies were recorded for each sample and the molecular vibrational frequ...
