N. Winogradsky Institute of Microbiology of the Russian Academy of Sciences, Pr. 60-letiya Octyabrya 7/2, Moscow, 117811, Russia Correspondence Margarita Grabovich margarita_grabov{at}mail.ru Five Gram-negative, motile, spiral-shaped strains were isolated from a sulfide spring (D-412 T ), active sludge of wastewater (D-419 T , D-420, D-424) and industrial wastewater (D-416). Comparative 16S rRNA gene sequence analysis showed that the isolates belong to the family Comamonadaceae , within the class Betaproteobacteria , but fall into a distinct cluster. On the basis of phenotypic, chemotaxonomic and phylogenetic data, a new genus, Giesbergeria gen. nov., is proposed, including five species. The type species of the genus is Giesbergeria voronezhensis sp. nov. (type strain D-419 T =DSM 12825 T =CIP 107340 T =VKM B-2350 T ) and other novel members of the genus are Giesbergeria kuznetsovii sp. nov. (type strain D-412 T =DSM 12827 T =VKM B-2352 T ), Giesbergeria giesbergeri comb. nov. (basonym Aquaspirillum giesbergeri ), Giesbergeria sinuosa comb. nov. (basonym Aquaspirillum sinuosum ) and Giesbergeria anulus comb. nov. (basonym Aquaspirillum anulus ). Using the same criteria, isolate D-416 (=DSM 12826) was identified as a strain of [ Aquaspirillum ] metamorphum . Strain D-416, the type strain of [ A .] metamorphum and the type strain of [ Aquaspirillum ] psychrophilum form a distinct cluster within the family Comamonadaceae (97–97·2 % 16S rRNA gene sequence similarity) and share phenotypic and chemotaxonomic properties. Therefore, it is proposed that these strains are reclassified as members of a new genus, Simplicispira gen. nov., as Simplicispira metamorpha comb. nov. (the type species) and Simplicispira psychrophila comb. nov., respectively. Published online ahead of print on 28 October 2005 as DOI 10.1099/ijs.0.64027-0. The GenBank/EMBL/DDBJ accession numbers for the 16S rRNA gene sequences of strains D-419 T , D-420, D-412 T and D-416 are AY780905 –AY780907 and AY780904 , respectively.
