Potential fructophilic characteristics of Lactobacillus apinorum, originally isolated from the guts of honeybees (Apis mellifera), were studied in the present study. The species showed typical fructophilic growth characteristics, i.e., active growth on D-fructose, poor growth on D-glucose, and accelerated growth on D-glucose in the presence of electron acceptors. Biochemical characteristics strongly supported classification of the species into fructophilic lactic acid bacteria (FLAB). Furthermore, genetic analyses suggested that the species underwent extensive gene reduction, similar to that recorded for Lactobacillus kunkeei and other FLAB. These data clearly indicated that L. apinorum is the second fructophilic species within the genus Lactobacillus.
