A Gram-negative, facultatively anaerobic, psychrophilic, motile rod, designated BZ59(T), was isolated from hydrocarbon-contaminated soil. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain BZ59(T) belonged to the genus Candidimonas and had highest 16S rRNA gene sequence similarity with Candidimonas nitroreducens SC-089(T) (97.7 %) and Candidimonas humi SC-092(T) (97.6 %). The ubiquinone was Q-8 and the major fatty acids were C(16 : 0), C(17 : 0) cyclo and summed feature 3 (C(16 : 1)ω7c and/or iso-C(15 : 0) 2-OH). The polar lipid profile contained the major compounds phosphatidylethanolamine, phosphatidylglycerol, phosphatidylmonomethylethanolamine and diphosphatidylglycerol. The major polyamines were putrescine and spermidine; a minor amount of 2-hydroxyputrescine was present. The DNA G+C content of strain BZ59(T) was 61.6 mol%. Combined data from phenotypic, phylogenetic and DNA-DNA relatedness studies demonstrated that strain BZ59(T) represents a novel species of the genus Candidimonas, for which the name Candidimonas bauzanensis sp. nov. is proposed. The type strain is BZ59(T) (= DSM 22805(T) = LMG 26046(T) = CGMCC 1.10190(T)). The description of the genus Candidimonas is emended.
