Planomicrobium koreense is a type of bacteria . The species is one of the firmicutes . Planomicrobium koreense wasisolatedfrom Korean fermented seafood Jeotgal . The new species Jeotgalicoccus psychrophilus and Jeotgalicoccus halotolerans were also found here.

features

Appearance

The cells are coccoid or short rods. After a while, the cocoids also change into rods. They are motile by a polar flagellum . The colonies show a yellow-orange color.

Growth and metabolism

Growth appears at temperatures between 4 and 38 ° C, optimal growth at 20–30 ° C. The pH value at which growth is possible is between 5.5 and 10, the best growth takes place at values ​​between pH 7.0 and 8.5. Growth takes place at an NaCl content of 0 to 6%, at 7% only weak growth occurs, and above 8% there is no more growth. The optimal NaCl content is 1 to 4%. Nitrate is not reduced.

The catalase test is positive, the oxidase and uredase test is negative. Esculin , casein and gelatin are hydrolyzed . Tests for the hydrolysis of arbutin , elastin , starch and polysorbate 80 (Tween 80), however, are negative.

Chemotaxonomic Features

They are gram-positive , but in old age the gram test can also turn out negative ( gram- variable). The GC content in the DNA is 47 mol percent. The predominant menaquinones are MK-8, MK-7 and Mk-6. The peptidoglycan type is A4α, of the type L- Lys- D -Glu.

Systematics

Planomicrobium koreense is part of the Planococcaceae family . It is the type species of its genus and was first described in 2001.
