AbstractOne hundred and twenty four isolates of acidotolerant acetic acid bacteria, isolated from various kinds of fruits and flowers collected in Chiang Mai, Thailand by an enrichment-culture approach were screened for their ability to produce rare ketose sugars. It was found that only 40 isolates (~32%)could produce L-sorbose from sorbitol as detected by cysteine-carbazole reaction. This was then confirmed based on the thin layer chromatography technique. However, when analysed by HPLC, only twenty-two isolates were capable of producing L-sorbose. Of these, the strain CMU 48-1 produced highest accumulation of L-sorbose (0.629%), and was identified as Gluconacetobacter liguefaciens based on 16S rRNA gene sequence analysis. This is the first report of biotransformation of L-sorbose from sorbitol by Gluconacetobacter liguefaciens
