Jung-Hoon Yoon found in Jeotgal also other new bacteria like "Jeotgalicoccus psychrophilus" and "Jeotgalicoccus halotolerans". The cells are rods. Sometimes they can be first coccoid but after some time they change to rods. "Planomicrobium koreense" is gram-positive. Sometimes the older cells change to gram negative. They have a single polar flagellum.
