RENDIMENTO 108,0g/l GRANULADO

Mode of Action
Only salt-tolerant microorganisms, including staphylococci, can grow on this
medium, because of its high salt concentration. Degradation of mannitol to
acid correlates, more or less, with the pathogenicity of Staph. aureus and thus
serves as an indicator for this species.
