- Аннотация: A novel nitrite-oxidizing bacterium (NOB) strain LbT , was isolated from a nitrifying bioreactor with high loading of ammonium bicarbonate in a mineral medium with nitrite as energy source. The cells are oval rods with pointed edges (lancet-shaped), nonmotile, Gram-positive (by staining and by the cell wall structure) and non-sporeforming. It is an obligately aerobic chemolitoautotrophic nitrite-oxidizing bacterium (NOB) utilizing nitrite or formate as energy source and CO2 as carbon source. Ammonium serves as the only source of assimilated nitrogen. Growth with nitrite was optimal at pH 6.8-7.5 and at 40o C (maximum 46o C). The membrane lipids consist of C20 alkyl 1,2-diols with the dominant fatty acids as 10MeC18 and C18:1 9. The peptidoglycan lacked meso-DAP but contained ornithine and lysine. The dominant lipoquinone is MK-8. Phylogenetic analyses of the 16s rRNA sequence placed strain LbT into the class Thermomicrobia of the phylum Chloroflexi with Sphaerobacter thermophilus as the closest relative. On the basis of physiological and phylogenetic data, it is proposed that strain LbT represents a new genus and species, Nitrolancea hollandica gen. nov., sp. nov. (LbT =DSM 23161T=UNIQEM U798T).
