A rod shaped, Gram-stain-negative, chemo-organotrophic, heterotrophic, strictly aerobic, non-gliding bacterium, designated strain PLR T , was isolated from faeces of the mollusc Aplysia punctata (Mollusca, Gastropoda) that had been fed with green algae belonging to genus Ulva . The novel able degrade ulvan, a polysaccharide extracted (Chlorophyta, Ulvophyceae). taxonomic position investigated by using polyphasic approach. Strain dark orange, oxidase-positive, catalase-positive and grew optimally at 25 °C, pH 7.5 in presence 2.5 % (w/v) NaCl an oxidative metabolism oxygen as electron acceptor. Nitrate could not be used Chargaff’s coefficient (DNA G+C content) 35.3 mol%. Phylogenetic analysis based on sequence 16S rRNA gene placed family Flavobacteriaceae (phylum ‘ Bacteroidetes ’), within clade comprising Stenothermobacter spongiae Nonlabens tegetincola Sandarakinotalea sediminis Persicivirga xylanidelens dokdonensis closest neighbours were P. sharing 95.2 95.5 similarity, respectively. inference differential phenotypic characteristics demonstrated represents species for which name ulvanivorans sp. nov. is proposed. type ( = CIP 110082 DSM 22727 ).
