a
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.
b
All sugars were present at a final concentration of 0.4 % (w/v).
c
Note growth of L. goodfellowii strains in absence of sugar.
d
α-MGlc: methyl-α-D-glucopyranoside.
e
Sugars in bold face are sucrose isomers.
f
(NG), no growth on designated sucrose isomer.
