Abstract A facultatively anaerobic, chemolithoautotrophic, sulfur-oxidizing bacterium, strain YK-1(T), was isolated from an underground crude-oil storage cavity at Kuji in Iwate, Japan. The cells were motile, curved rods and had a single polar flagellum. Optimum growth occurred in a low-strength salt medium at pH 7.0 and 25 degrees C. It utilized sulfide, elemental sulfur, thiosulfate and hydrogen as the electron donors and nitrate as the electron acceptor under anaerobic conditions, but it did not use nitrite. Oxygen also served as the electron acceptor under the microaerobic condition (O(2) in the head space 1 %). It did not grow on sugars, organic acids or hydrocarbons as carbon and energy sources. The DNA G+C content of strain YK-1(T) was 45 mol%. Phylogenetic analysis, based on the 16S rRNA gene sequence, showed that its closest relative was Thiomicrospira denitrificans in the 'Epsilonproteobacteria', albeit with low homology (90 %). On the basis of physiological and phylogenetic data, strain YK-1(T) should be classified into a novel genus and species, for which the name Sulfuricurvum kujiense gen. nov., sp. nov. is proposed. The type strain is YK-1(T) (=JCM 11577(T)=MBIC 06352(T)=ATCC BAA-921(T)).
