Hello, What curiocity can you tell me about Methicillin-resistant Staphylococcus aureus? Thank you in advance!

Your lazy labmate needs your help! They set up a 10-ml culture of the slow-growing Myxococcus xanthus yesterday, but then they decided to stay up late playing videogames and won't be in until next Monday to recover. Whoops! They call you in lab that Friday and ask you to take an OD reading for them. You do this favor for them, and helpfully do the conversion into cells/mL, finding that their culture is currently sitting at about 3.0 x108 cells per mL. Your labmate is horrified: they won't be back in time before the cells hit stationary phase, since M. xanthus doubles every 5 hours. They beg you to make a new culture using these cells and set it up to reach the same cell density Monday morning. That's 59 hours away. If the cells usually lag for three hours upon dilution into fresh medium, what cell density should you dilute the culture to? About 1.3 x 107 cells/ml About 1.3 x 105 cells/ml About 1.3 x 106 cells/ml About 1.3 x 104 cells/ml

Help me, please! I wish I have a lot of time to do it by myself ...

I AM TRYING TO IDENTIFY THIS UNKNOWN. IMAGE 1 HAS TWO PICTURE OF CATALASE TEST AND BLOOD AGAR TEST. I believe it is one of the following: 1) S. pyo.    2)S. agal .     3)S.pneu.   4)E. faecalis                  5)S. aureus       6)S epi.       7)S. sapro.        8)M. luteus   Please let me know which test will i need out of the table to justify your reason of picking up the unknown and also how that test justifies it? what characteristics of that test made you pick the unknown?
