Title

Nisaea denitrificans gen. nov., sp. nov. and Nisaea nitritireducens sp. nov., two novel members of the class Alphaproteobacteria from the Mediterranean Sea

Abstract

Two novel Gram-negative bacteria, designated strains DR41_21^T and DR41_18^T, were isolated from coastal, surface waters of the north-western Mediterranean Sea. The cells were motile, pleomorphic rods, 2.9 µm long and 0.9 µm wide and formed cream colonies on marine agar medium. The G+C content of the genomic DNA was 60 mol%. Phylogenetic analysis of 16S rRNA gene sequences positioned the isolates in the class Alphaproteobacteria within the family Rhodospirillaceae. The 16S rRNA gene sequence similarity of the two strains was 98.8 % but DNA–DNA hybridization indicated only 55 % relatedness. Strain DR41_21^T was able to denitrify and possessed nirK and nosZ genes, unlike strain DR41_18^T, which possessed only nirK. These isolates represent two novel species of a new genus, Nisaea gen. nov., for which the names Nisaea denitrificans sp. nov. and Nisaea nitritireducens sp. nov. are proposed. The type strain of Nisaea denitrificans is DR41_21^T (=DSM 18348^T=CIP 109265^T=OOB 129^T) and the type strain of Nisaea nitritireducens is DR41_18^T (=DSM 19540^T=CIP 109601^T=OOB 128^T).
