| Penicillium notatum Westling |
Penicillium notatum, also known as Penicillium chrysogenum, is a mold commonly found in most homes and a basis of Beta-lactam antibiotics. Penicillium is known as the blue-green mold on bread, fruits, and nuts. It is also used for the production of green and blue mould cheese.
Penicillium grows at its peak during the spring and winter, but the mold has no seasonal variation. It is a well-known group of brushed-shaped microorganisms belonging to the fungimycin family, and has no known sexual state. Penicillium is heterotrophic.
[edit] Discovery
Penicillium was discovered when Alexander Fleming's lab assistant left a window open overnight and let mold spores cover his bacteria specimens. At first he was very irritated at the contamination but as he was about to throw the specimens away he noticed somthing odd. He looked under the microscope at the bacteria and where the mold grew the bacteria was dead or dying. He had discovered the mold penicillium notatum.
