pH-Chromatography of antibiotics. I. Biosynthesis of penicillin
Slovak Technical University,
Abstract: By the method of pH-chromatography (CA 53, 9351e) some biosynthetic penicillins were studied. In addn. to pure prepns., the filtrate of the fermentation substrate contg. benzylpenicillin was tested. It was detd. that the side radicals of biosynthetic penicillins had little effect on the character of Rf curves. The relation of Rf values on sepn. coeffs. of benzylpenicillin between H2O and CHCl3 at the corresponding pH values was detd. The data of pH chromatograms indicate that there is a possibility of isolation and concn. of antibiotics by applying extn. and reextn.
