High-resolution phylogenetic analysis of NO2--oxidizing Nitrobacter species using the rrs-rrl IGS sequence and rrl genes

A high-resolution phylogenetic analysis of Nitrobacter strains and their neighbours was made using the rrs-rrl intergenic spacer sequence and the hypervariable part of the rrl gene. The phylogenetic tree obtained was hypervariable parr or the rrl gene. The phylogenetic tree obtained was consistent with that which was obtained previously but was much more discriminating, permitting the design of genus-specific primers.
