Abstract
The selective isolation of sorbitol utilizing acetic acid bacteria using specific enrichment medium in combination with the incubation temperature of 37 °C was reported. The medium which composed of 0.5 % glucono-delta-lactone and 1% sorbitol has been used for the selective isolation of acetic acid bacteria from flowers, fruits and vegetables. A total of 48 acetic acid bacteria were successfully recovered from the samples. Among these isolates, 85% were sorbitol utilizing acetic acid bacteria which grew well at 37 °C. Morphological and biochemical determinations indicated that all isolates are member of the genus Gluconobacter.
