An aerobic, gliding, yellow-pigmented bacterium lacking flagella and showing strong tyrosinase activity, designated strain EM41T, was isolated from seawater on the eastern coast of Jeju Island in Korea. Growth was observed at 15–35 °C (optimum, 25–30 °C) and at pH 6.5–9.0 (optimum, pH 7.0–8.5). Cells were Gram-negative, negative for flexirubin pigments and catalase- and oxidase-positive. The G+C content of the genomic DNA was 33.5 mol% and the major respiratory quinone was menaquinone-6 (MK-6). Comparative 16S rRNA gene sequence analysis showed that strain EM41T formed a distinct phyletic line within the genus Cellulophaga with a 100 % bootstrap value and was most closely related to Cellulophaga pacifica KMM 3664T (97.0 % sequence similarity). The level of DNA–DNA relatedness between strain EM41T and C. pacifica KMM 3664T was about 17.8 %. On the basis of phenotypic and genotypic data, strain EM41T is considered to represent a novel species of the genus Cellulophaga, for which the name Cellulophaga tyrosinoxydans sp. nov. is proposed. The type strain is EM41T (=KCTC 22297T=DSM 21164T).

The GenBank/EMBL/DDBJ accession number for the 16S rRNA gene sequence of strain EM41T is EU443205.

A transmission electron micrograph of cells of strain EM41T is available with the online version of this paper.
