Sodium chloride  maintains  the osmotic  balance  in  the  medium.  The  low  pH  of  the  medium,  combined  with  the  presence  of  Malachite green and Magnesium chloride raises the osmotic pressure and Potassium dihydrogen phosphate acts as a  buffer,  selective  for  the  highly  resistant Salmonella species.  Malachite  green  is  inhibitory  to  organisms other  than Salmonella sp.  Novobiocin  is  added  as  a  selective  agent. When  Rappaport  Vassiliadis Salmonella Enrichment Broth medium is combined with direct culture and Selenite enrichment, 98.9% of Salmonellaare recovered
