What biochemical test can we use to differentiate S aureus from S epidermidis?

multiplex PCR
aureus and Staph. epidermidis. Accordingly, a multiplex PCR was developed and we found that a single gene encoding the adhesin fibrinogen binding protein could be used to identify and differentiate the two species.

Is S epidermidis Gram-positive or negative?
