Some factors influencing the production of certain biosynthetic penicillins.
Basic media. (a) Natural. A medium containing 4 per cent corn steep solids, 4 per cent lactose, 1.5 per cent Cerelosel (92 per cent glucose) and 0.0044 per cent ZnSO4-7H20 was prepared in 95 per cent of the final volume. After adjustment to pH 5.6 to 5.8, it was sterilized by autoclaving. A suspension (20 per cent) of calcium carbonate was autoclaved separately. The calcium carbonate suspension...
متن کاملSome new biosynthetic penicillins.
In our laboratories some 200 compounds, including phenylacetic acid derivatives, have been studied as possible precursors for new penicillins, and several of these appeared to give rise to new penicillins. In this report, five new penicillins, four of which were obtained in crystalline form, are described and their production, isolation, and characterization discussed. The methods employed in o...
متن کاملBiosynthesis of penicillins; new crystalline biosynthetic penicillins.
Paper III (1) in this series describes several tests which were found to be useful in determining whether a given compound is utilized by the mold in penicillin formation. To provide proof of the incorporation of various acyl groups into the penicillin molecule and to be able to determine the chemical characteristics and biological properties of the various penicillins, isolation and crystalliz...

15 صفحه اولSome 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...
