Abstract

Improvements made in a process for the preparation of 7- (D-5-amino-5-carboxyvaleramido) -3- (carbamoyloxymethyl) -7-methoxy-3-cephem-4-carboxylic acid by cultivating a new actinomycete in a nutrient medium, characterized in that the improvements consist of adding to the nutrient medium, alone or in combination, sodium thiosulfate, sodium dithionite or α-aminoadipic acid.
