Para-aminobenzoic Acid Production by Staphylococci
1. Strains of staphylococci produce diazotizable materials which can be converted to a dye, and the intensity of the color reaction can be quantitated in the same manner as p-aminobenzoic acid. The sulfonamide-resistant strains which we have studied produce more diazotizable substance than non-resistant strains. 2. The development of a color by the diazotizable substance can be inhibited by exp...
متن کاملSeparation of p-Aminobenzoic Acid Derivatives
According to the literature, p-aminobenzoic acid (PAB) is excreted in the urine mostly as the free acid and its N-acetyl derivative; the remaining part is eliminated conjugated with glucuronic acid and as p-aminohippuric acid (PAH) (Ellinger & Hensel, 1914'; Hensel, 1914; Cohen & McGilvery, 1946; Salassa, Bollman & Dry, 1948). There is no agreement concerning the formation of PAH. Thus, Beyer, ...
متن کاملPhysico-chemical studies of some aminobenzoic acid hydrazide complexes
The stability constants and related thermodynamic functions characterizing the formation of divalent Ni, Cu, Zn, Cd and Hg complexes with oand p-aminobenzoic acid hydrazide were determined potentiometrically at different temperatures. The formations of the complexes are endothermic processes. The formed bonds are mainly electrostatic. Conductometric titration was carried out to determine the st...
متن کاملTHE ISOLATION OF p-AMINOBENZOIC ACID FROM YEAST
The present investigation is primarily concerned with the isolation of p-aminobenzoic acid from yeast. The presence of this substance in yeast was adumbrated by Woods (1) who made the important discovery that. this aromatic amino acid possesses the unique propcity of antagonizing the bsctcriostat~ic action of sulfanilamidt? and that the component. of yeast extracts which exerts a similar antisu...
متن کاملA MICROBIOLOGICAL ASSAY METHOD FOR p-AMINOBENZOIC ACID
Since the eshablishment of p-aminobenzoic acid as a member of the B vitamin group, a considerable interest has been shown in methods of determination in natural materials. Since known chemical methods are not sufficiently sensitive, it became evident that microbiological tests should be the most practicable. The organism Clostridium acetobutylicum has been used (I) but no general assay procedur...
