title: Phylogeny of the ring-forming bacterium Arcicella aquatica gen. nov., sp. nov. (ex Nikitin et al. 1994), from a freshwater neuston biofilm.
abstract: Arcicella aquatica NO-502(T), obtained from a neuston film on a freshwater lake and belonging to the phylum Bacteroidetes, is characterized by ring-forming cells. The bacterium is a strict aerobe, with optimal growth between 28 and 30 degrees C. Carbohydrates, but no organic acids or amino acids, are used as substrates. The G+C content of strain NO-502(T) is 34.5 mol%; its genome size is 2.9 x 10(9) Da. The genus Arcicella and its type species Arcicella aquatica (type strain NO-502(T)=LMG 21963(T)=CIP 107990(T)) are proposed, and descriptions of this genus and species are given.
