From the production of pigment I think that you can only say that the strain is S. aureus or non-S.aureus. Although some mutant S. aureus can be without golden pigment but those strains are sensitive to oxidizing chemicals (H2O2). So buy cultivation and looking at pigmentation you can get limited amount of results concerning the strain typisation. 

Thank you dear Nikola for paying attention. Mercy

Para que S. aureus produzca su pigmento amarillo puedes cultivarlo en medio S110  por 24 hrs en atmosfera parcial de anaerobiosis y 24 hrs mas en aerobiosis, también dependerá de la cepa que tengas, hay cepas que pigmentan muy poco.
