False-colour scanning electron micrograph (SEM) of Penicillium chrysogenum,the species of penicillin fungus from which the antibiotic is manufactured. The micrograph shows a close-up of the fungal spores,or conidia. The conidia are in fact green in colour,which is why mouldy cheese often looks green. The slightest movement of air causes the conidia to be detached & blown away. Penicillium species are the most widespread moulds,& the air is full of their conidia. It was the chance arrival of a spore of P. notatum on a bacterial plate that led to Alexander Fleming's discovery of penicillin as an antibiotic. Magnification: x2850 at 35mm size | |
