Cephalosporin C is an antibiotic of the cephalosporin class. It was isolated from fungi of the genus Acremonium and first characterized in 1961. Although not a very active antibiotic itself, synthetic analogs of cephalosporin C, such as cefalotin, became some of the first marketed cephalosporin antibiotic drugs.
