Biofilm formation and exopolysaccharide (EPS) production by Cronobacter sakazakii depending on environmental conditions

► Biofilm matrices are formed largely of extracellular polysaccharides. ► Biofilm formation and EPS productin of Cronobacter sakazakii were investigated. ► C. sakazakii produce large amount of EPS when 3% sucrose was supplemented. ► EPS production by C. sakazakii was different depending on nutrients provided.
