A type of blue-green mold (Date of photograph unknown)
Penicillium. Coloured Scanning Electron Micrograph (SEM) of the mycelium and fruiting bodies of the fungus Penicillium sp. Penicillin mould grows as a mycelium of hyphal threads, as seen here, many of which have developed into fruiting bodies. The fruiting bodies, known as conidia, are tuft-like clusters at the tips of hyphae which contain rounded spores strung together in chains. Once ripe each spore can germinate into a new fungus. Species of Penicillium are the source of antibiotic penicillin for use as drugs to combat bacterial infection. They are also used in the fermentation of roquefort and camembert cheeses.
