Demonstration of exopolysaccharide production by enterohemorrhagic Escherichia coli.

Current microbiology - 1 Jul 1992

Junkins A D, Doyle M P

Abstract excerpt

Enterohemorrhagic Escherichia coli O157:H7 produces visibly slimy colonies when grown on Sorbitol/MacConkey or Maloney's agar plates at room temperature, indicative of exopolysaccharide (EPS) production. Eighteen of 27 (67%) wild-type E. coli O157:H7 isolates produced enough EPS to be visually distinguishable. Of five strains that showed no visible EPS production on these media, four (80%) did produce slimy...
