| Substituting sugar (concn [mM])a | Metabolic capacityb | Biofilm formationc |
|---|---|---|
| Glucose (111) | + | +++ |
| Glucose (55) | + | + |
| Glucose (222) | + | + |
| Lactose (111) | − | − |
| Lactose (55) | − | − |
| Saccharose (111) | − | − |
| Saccharose (55) | − | − |
| Maltose (111) | + | − |
| Maltose (55) | + | +++ |

| Galactose (111) | + | +++ |
a
Either the concentration of glucose in standard ATM was changed or another sugar was substituted for glucose and the bacteria were incubated in the different solutions as described in Materials and Methods.
b
Capacity of S. enteritidis to metabolize sugar.
c
Biofilm formation was subjectively quantified from + to +++.
