Genus species: Tenacibaculum adriaticum

Description and significance

A rod-shaped, translucent yellow-pigmented, Gram-negative bacterium that are 0.3 μm wide and 1.5–3.5 μm long, and are non-flagellated but motile by means of gliding. During stationary phase and under suboptimal growth conditions they could appear as spherical cells (0.5–0.8 μm in diameter) while longer rods (up to 35 μm in length) are observed regularly.

Growth

The microbe grew at the temperature 5-34 degrees C, with optimal growth at 18-26 degrees C, and only in the presence of NaCl(optimum 1–2 %)or sea salts up to 70 g l^−1. They also grow at pH 5–9, with an optimum at pH 7. When they form colonies they appear circular with a regular edge and translucent yellow.

Metabolism

"Aesculin, casein, tyrosine, starch and gelatin are hydrolysed. Oxidase-positive. According to Biolog tests, α-cyclodextrin, dextrin, glycogen, cellobiose, gentiobiose, maltose, D-glucose 6-phosphate, succinic acid, succinamic acid and succinic acid monomethyl ester are utilized, as well as Tween 40, maltose, acetic acid, D- and L-lactic acid, L-aspartic acid, L-glutamic acid, glycyl L-aspartic acid, glycyl L-glutamic acid, L-ornithine and L-proline as carbon sources. The G+C content of the DNA of the type strain is 31.6 mol%. The major isoprenoid quinone is MK-6 (98.5 %). Major fatty acids are iso-C15 : 0 (25.3 %), iso-C15 : 0 3-OH (13.7 %) and iso-C15 : 1 (13.1 %)."

Environment

Tenacibaculum adriaticum B390 is isolated from the bryozoan Schizobrachiella sanguinea from the Adriatic Sea. The Adriatic Sea is located
