General description
MSRV Selective Supplement contains novobiocin sodium salt in
lyophilized form. Novobiocin suppresses the growth and motility of most of the
competitor flora during culturing Salmonellae. It also prevents the swarming
of Proteus spp.
Application
MSRV Selective Supplement is an additive for the preparation
of MSRV medium (1.09878) for isolation of Salmonella spp.
