Abstract A mixed bacterial culture capable of growing in potassium-thiocyanatecontaining medium (200 mg KSCN) has been isolated from bacterial suspensions of soilsamples collected near gold mines in Kumjung (Korea). The isolates were initially characterized by metabolic profile analysis and were identified as Bacillus thermoglucosidasius,Bacillus cereus, Bacillus licheniformis, Bacillus mycoides, Brevibacteriumepidermidis, Brevibacterium otitidis, and Corynebacterium nitrilophilus.One of the seven isolates was initially characterized as Brevibacterium epidermidis,which is not known to degrade thiocyanate. However, using 16S rDNA sequencing, thisstrain was identified as a member of Klebsiella. The strain shows high similarityvalues (95.8 to 96.4%) with Klebsiella species, and the closest known relative was foundto be K. ornithinolytica ATCC 31898. The result indicates that species of the genusKlebsiella were the closest phylogenetic relatives of the investigated strain. This isthe first known report of a member of Klebsiella that is capable of utilizing thiocyanate assole source of carbon and nitrogen.
