Abstract: Title compd. (I) useful as antibiotics, and its salts were prepd. from the culture filtrate of Streptomyces clavuligerus NRRL 3585. Thus, 25l inoculum grown on a complex medium was mixed with 475l of a medium contg. soybean meal 3.0, FeSO47H2O 0.01, K2HPO40.01, sol. starch 4.7%, and silicon antifoaming agent 0.05% and cultured in 700l fermentor for 2 hr at 28≦̸C and pH 6.5 with agitation and aeration at 0.56 v/v/min. The culture filtrate was decolorized with active C, the column washed with 90l water, and I eluted with 180l of 60% acetone.

Abstract: Broad-spectrum antibiotics are prepared by combining a broad-spectrum cephalosporin antibiotic (A) which is subject to decomposition by beta-lactamase, with a cephalosporin antibiotic (B) which is beta-lactamase resistant. Cephalosporin antibiotic (A) of general formula (I): R4 = 2-thienylmethyl or D-alpha-amino alpha-phenylmethyl; R5 = an acetate group or, in the betaine-form with the adjacent carboxyl group, a Py+ group; Py = N-pyridyl or subst. N-pyridyl group. Cephalosporin antibiotic (B) The new preparations contain a cephalosporin antibiotic (II) which is resistant to decomposition caused by beta-lactamase produced by Proteus morgani. The antibiotic (I) with broad spectrum is protected by (II) which increases the spectrum and/or its activity.
