Staphylococcus aureus, sterol

The bacterial genus Mycoplasma Is well known for the occurrence of and dependence on sterols [3], but these bacteria without cell walls do not synthesize their sterols by themselves [4]. Bacterial species which contain and synthesize sterols by themselves are Methylococcus capsulatus [5,6], Hannocystls exedens [7] and an L-form of Staphylococcus aureus [8]. It Is Interesting to note that Methylococcus capsulatus simultaneously contains hopanolds [6].
