  • Selective salmonella carbohydrate and medium constructed therefrom
    Patent number: 4279995
    Abstract: 2-Deoxy-D-Ribose is used as a carbohydrate source which selectively differentiates all of the Salmonella spp., Arizona spp., and 60% of the Citrobacter freundii from other members of the Enterobacteriaceae family. By combining the 2-Deoxy-D-Ribose with Citrobacter freundii inhibitors and thioglycollic acid, sodium salt to impart semi-anaerobic conditions in the medium as well as suitable nutrients and buffers, a selective Salmonella broth is compounded which lends itself to automated identification or enumeration systems.
