Аннотация:Fluoroquinolones are synthetic antimicrobial agents that are active against a broad spectrum of pathogenic gram-negative bacteria as well as some gram-positive bacteria and mycoplasmas. Several fluoroquinolones are used in clinical medicine. The metabolism of enrofloxacin by Mucor ramannianus was investigated as a model for the biotransformation of veterinary fluoroquinolones by zygomycetous fungi.
