For isolation and differentiation of lactose fermenting and non-fermenting lactose enteric bacteria. It is recommended by BIS committee under specification IS: 5887 (Part I and II) 1976, reaffirmed 2005 MacCONKEY Agaris  used  forisolation  and  differentiation  of  lactose  fermenting  and  non-fermenting lactose  enteric  bacteria. The    medium    contains    Peptic    digest    of    animal      tissue    which    provides    the  nitrogeneous  and  other  essential  growth  compounds.  Sodium chloride maintains the osmotic balance of the cells.Gram-negative bacteria usually grow well on thismedia and are differentiated by their ability to ferment lactose. Lactose fermenting strains grow as red or pink and may be surroundedby a zone of acid  precipitated  bile.The  medium  turns  pink  in  case  of  lactosefermenters  andyellow  in  case  of  non-lactose-fermenters, due to neutral red when the pH of the media falls below 6.8. Lactose non-fermenting strains,  such  as Shigella and Salmonellaare  colourless  and  transparent  and  typically  donot  alter appearance of the medium.Sodium taurocholate is used as a selective agent. Agar is a solidifying agent.
