title: Aquitalea denitrificans sp. nov., isolated from a Korean wetland.
abstract: A novel bacterium, designated strain 5YN1-3(T), was isolated from wetland peat collected from Yongneup, Korea. The bacterium was facultatively anaerobic, Gram-negative, yellow-coloured, rod-shaped, mesophilic and motile with one polar flagellum. The strain grew optimally at 30 degrees C, at pH 6.0-9.0 and with 0-1 % NaCl (w/v). 16S rRNA gene sequence analysis showed the highest similarity to the sequence from Aquitalea magnusonii TRO-001DR8(T), with 98.7 % sequence similarity. However, strain 5YN1-3(T) showed DNA-DNA relatedness of 43 % (40 % in a reciprocal experiment) with A. magnusonii LMG 23054(T). The strain contained summed feature 3 (iso-C(15 : 0) 2-OH and/or C(16 : 1)omega7c) and C(16 : 0) as major cellular fatty acids. On the basis of DNA-DNA relatedness and physiological and biochemical characterization, strain 5YN1-3(T) should be assigned to a novel species of the genus Aquitalea, for which the name Aquitalea denitrificans sp. nov. is proposed. The type strain is 5YN1-3(T) (=KACC 12729(T) =DSM 21300(T)).
