Is Staphylococcus aureus Endospore forming?

Staphylococci are microbiologically characterized as gram-positive (in young cultures), non-spore-forming, nonmotile, facultative anaerobes (not requiring oxygen). Gram-positive Staphylococcus aureus, from a laboratory culture. Of significance to humans are various strains of the species S. aureus and S. epidermidis.

Subsequently, one may also ask, is Staphylococcus aureus facultative anaerobe?

S. aureus is often hemolytic on blood agar; S. epidermidis is non hemolytic. Staphylococci are facultative anaerobes that grow by aerobic respiration or by fermentation that yields principally lactic acid. The bacteria are catalase-positive and oxidase-negative.

Is Staphylococcus epidermidis an obligate Aerobe?

It is a catalase-positive, coagulase-negative, facultative anaerobe that can grow by aerobic respiration or by fermentation. It is sensitive to novobiocin, providing an important test to distinguish it from Staphylococcus saprophyticus, which is coagulase-negative, as well, but novobiocin-resistant.

Is Micrococcus luteus an obligate Aerobe?

Micrococcus luteus. Micrococcus luteus is a Gram-positive, to Gram-variable, nonmotile, coccus, tetrad-arranging, pigmented, saprotrophic bacterium that belongs to the family Micrococcaceae. An obligate aerobe, M. luteus is found in soil, dust, water and air, and as part of the normal flora of the mammalian skin.
