caption_attribution_description: English: Fungi (ascomycetes) growing in axenic cultures, each of which is a culture of one selected organism and is free of all other organisms, enabling study of the cultured organism in isolation. The fungi were obtained from soil.
context_page_description: Penicillium is a genus of ascomycetous fungi that is of major importance in the natural environment, in food spoilage, and in food and drug production.
  Some members of the genus produce penicillin, a molecule that is used as an antibiotic, which kills or stops the growth of certain kinds of bacteria. Other species are used in cheesemaking. According to the Dictionary of the Fungi, the widespread genus contains over 300 species.
