Sugar uptake and phosphoenolpyruvate phosphorylation assays have shown that the heterofermentative strain Lactobacillus reuteri CRL 1098, of likely probiotic value, can transport D ‐fructose through an inducible fructose‐specific phosphotransferase system ( K m 95 μM) and D ‐glucose mainly through a proton motive force‐driven permease. These data open new perspectives for metabolic and regulatory studies in this bacterium.
