PURPOSE:An antibiotic-producing microorganism in Cephalosporium is cultured to obtain a compound having a function of promoting the production of cephalosporin C. CONSTITUTION:A compound having a function of promoting the production of cephalosporin C is obtained by cultivation of Cephalosporium acremonium ATCC 14553 and isolation and purification by means of chromatography of the culture mixture. The compound has a molecular formula: C10H14O5N2, being characterized by the mass spectrum of its trimethylsilyl derivative, the mass spectrum of its acetyl derivative, the proton NMR spectrum, ultraviolet spectra under different pH conditions and the circular dichromic spectrum. |
