Strain: B390

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. (1)


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. (1)


"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 %)." (1)


Tenacibaculum adriaticum B390 is isolated from the bryozoan Schizobrachiella sanguinea from the Adriatic Sea. The Adriatic Sea is part of the Mediterranean Sea and is positioned between the eastern coastline of Italy, and countries of the Balkan Peninsula, from Slovenia, south through Croatia.(3) "The Adriatic Sea is about 500 miles (800 km) long, northwest-southeast, and up to 140 miles (225 km) wide. It has an area of approximately 51,000 square miles (132,000 km 2 ), slightly less than that of Lakes Superior and Michigan combined. The Adriatic is one of the shallowest parts of the Mediterranean, with an average depth of about 800 feet (240 m). The deepest spot, 4,034 feet (1,230 m), is about midway between Bari, Italy, and the coast of Montenegro." (4)
