Summary: | T Barbeyron, S L'Haridon, E Corre, B Kloareg and P Potin
Station Biologique de Roscoff, UMR 1931 (CNRS and Laboratoire Goemar), Place Georges Teissier, 29682 Roscoff Cedex, Bretagne, France
A mesophilic, aerobic, non-flagellated, gliding bacterium, forming yellow
colonies and designated Dsij(T), was isolated from a red alga on the
sea-shore of Roscoff, Brittany, France. Dsij(T) was selected for its
ability to actively degrade both agars and carrageenans. The Gram-negative
cells occurred singly or in pairs as long rods. The temperature range for
growth was 13--45 degrees C, with an optimum at 35 degrees C. The pH range
for growth at 35 degrees C was from 6.0 to 8.5, with an optimum around pH
7.0. The NaCl concentrations required for growth at 35 degrees C and pH 7.0
ranged from 5 to 60 g l(-1), with an optimum around 25 g l(-1). The G+C
content of the genomic DNA was 42--43 mol%. Phylogenetic analysis of 16S
rRNA gene sequences indicated that strain Dsij(T) is closely related to
[Cytophaga] uliginosa DSM 2061(T). Phenotypic features, however, allowed
Dsij(T) and [Cytophaga] uliginosa strains to be distinguished on the basis
of ten traits (spreading behaviour, assimilation of eight compounds and
amylase production). Their total protein profiles were also different and
DNA--DNA hybridization experiments confirmed that Dsij(T) constitutes a new
species, distinct from [Cytophaga] uliginosa. Based on the phenotypic
features and the phylogenetic relationships of the Flavobacteriaceae, a new
genus designated Zobellia gen. nov. is proposed to include Zobellia
galactanovorans gen. nov., sp. nov., while [Cytophaga] uliginosa becomes
Zobellia uliginosa comb. nov. The type strain of Zobellia galactanovorans
is Dsij(T) (=DSM 12802(T)=CIP 106680(T)). |
