Description

Differentiate members of Enterobacteriaceae based on sodium malonate utilization using Malonate Broth (Ewing Modification).

Differentiate members of Enterobacteriaceae based on sodium malonate utilization using Thermo Scientific™ Remel™ Malonate Broth (Ewing Modification). Malonate Broth is recommended to differentiate certain subgroups of Salmonella from other Enterobacteriaceae1. Leifson developed a liquid medium to differentiate Escherichia coli from Enterobacter spp2. Ewing et al. modified the Leifson's formulation by adding a trace amount of dextrose and yeast extract to stimulate growth of certain organsims that fail to grow and obseved their reaction on malonate3,4.

Differentiate members of Enterobacteriaceae based on sodium malonate utilization using Malonate Broth (Ewing Modification).

  • Recommended to differentiate certain subgroups of Salmonella from other Enterobacteriaceae1
  • Blue color development due to utilization of malonate is easy to interpret
  • Ready to use – Convenience of prepared media

An organism that utilizes sodium malonate as a carbon source and ammonia sulfate as a nitrogen source produces an alkaline reaction and organisms which cannot utilize malonate will ferment dextrose, causes the pH indicator to change from green to yellow thus producing an acid reaction.
