title: Tween-esterase activity in Enterobacter sakazakii.
abstract: Seventy-one of 73 E. sakazakii strains isolated in Czechoslovakia produced Tween 80 esterase; its production was slower and less intensive than in Serratia, vibrios and aeromonads. The E. sakazakii strains did not produce lecithinase (yolk reaction was negative for 8 days). The following set of tests was recommended for verification of E. sakazakii identification: pigment (was produced by 100% of strains), Tween 80 esterase (was positive in 97.3%), mucate (negative in 100%) and sorbitol (negative in 100%).
