Organisms were grown anaerobically at 37 °C, and after 48h, growth was recorded (A600nm) using a Beckman DU 640 spectrophotometer. Results are mean values from two experiments.
All sugars were present at a final concentration of 0.4 % (w/v).
Note growth of L. goodfellowii strains in absence of sugar.
α-MGlc: methyl-α-D-glucopyranoside.
Sugars in bold face are sucrose isomers.
(NG), no growth on designated sucrose isomer.
