A bacterium utilizing cyclopentanone as a sole carbon and energy source, strain KUG-5N, was isolated from soil by enrichment cultures. Taxonomical studies indicated that strain KUG-5N was of genus Aeromonas. Strain KUG-5N was grown on a synthetic medium containing cyclopentanone, 5.0 g; NH_4H_2PO_4,3.0 g; KH_2PO_4,1.5 g; Na_2HPO_4,1.5 g; MgSO_4・7H_2O, 0.2 g; CaCl_2・2H_2O, 0.01 g; FeSO_4・7H_2O, 5m g; MnSO_4・4H_2O, 2m g; and yeast extract, 0.1 g, in 1 l of distilled water, The pH was adjusted to 8.0. The generation time of strain KUG-5N on cyclopentanone was 9.0 h and the specific growht rate (μ<max>) was 0.35 h^<-1>. Strain KUG-5N could also utilize two other kinds of alicyclic compounds, cyclopentanecarboxylic acid and cyclohexanecarboxylic acid.
