Abstract

A Gram-negative, rod-shaped, non-spore-forming betaproteobacterium (TRO-001DR8T) was isolated from humic-lake samples collected from northern Wisconsin, USA. On the basis of 16S rRNA gene sequence analysis, strain TRO-001DR8T belonged to the family Neisseriaceae, and the phylogenetic distance from its closest relative, Chromobacterium violaceum, was 95 %. Strain TRO-001DR8T lacked the violet pigmentation of C. violaceum and shared only 26 % DNA-DNA relatedness with C. violaceum. The DNA G+C content of strain TRO-001DR8T was 59 mol%. The predominant fatty acids were C(16 : 1)omega7c + C(16 : 1)omega7c 2-OH iso (52.5 %), C(16 : 0) (21.7 %), C(18 : 1)omega7c (8.0 %) and C(12 : 0) (5.1 %). Strain TRO-001DR8T grew optimally at 35 degrees C and pH 6.0, did not utilize sucrose, but did use glucose, some organic acids and most protein amino acids. Biochemical, physiological, chemotaxonomic and phylogenetic analyses showed that strain TRO-001DR8T could not be assigned to any known genus of the Betaproteobacteria. Therefore, the isolate represents a novel genus and species, for which the name Aquitalea magnusonii gen. nov., sp. nov. is proposed. The type strain is TRO-001DR8T (=ATCC BAA-1216T = BCCM/LMG 23054T).
