Staphylococcus aureus produces round, opaque colonies and can grow at any temperature between 10 and 46 degrees Celsius. It grows well with the help of oxygen and carbon dioxide. Most strains are metabolically versatile where they digest proteins and lipids and ferment a variety of sugars. Staphylococci are facultative anaerobes that grow by aerobic respiration or by fermentation that produces lactic acid. The species is considered among the most resistant of all non-spore forming pathogens. It stays alive after months of air drying and
