Description

Enumerate and differentiate coliforms from water and food samples with this selective, differential medium when used with TTC Solution Supplement.

Enumerate and differentiate coliforms from water and food samples with selective Thermo Scientific™ Oxoid™ Tergitol-7 Agar (Dehydrated) when used with TTC Solution Supplement (SR0148). Tergitol 7 inhibits Gram-positive organisms allowing superior recovery of coliforms. Fermentation of lactose is seen by a change in color of the pH indicator bromothymol blue. Tri-phenyltetrazolium chloride (TTC) is rapidly reduced to red formazan by most coliform organisms except Escherichia coli and Enterobacter aerogenes allowing easy differentiation.

Tergitol-7 Agar is based on the formulation described by Chapman1 and is recommended for the selective isolation and differentiation of the coliform group.

  • Easy-to-read: easily differentiate Escherichia coli (yellow colonies) and Enterobacter species (greenish/yellow colonies) from coliforms (red colonies).
  • Selective: Tergitol-7 inhibits Gram positive organisms and minimizes the swarming of Proteus, allowing superior recovery of coliforms.
  • Recommended: for examination of foodstuffs for fecal contamination2.
