General information
Name
Ichthyenterobacterium magnum
Valid publication
2015
Nomenclature type
Th6;KCTC 32140
;JCM 18636
;DSM 26283
Etymology
L. n. <i>magnus</i>, big, referring to cell size.
Ecology
Source
isolated from the intestine of cultured flounder (Paralichthys olivaceus) collected from a fish farm in Shandong province, PR China.
Morphology
Cell morphology varies with the age of the culture. In the exponential phase, cells are curved rods (0.5-0.6 × 1.5-5 µm), and form compact microcolonies. In the stationary phase, cells are pleomorphic rods of vibroid and spiral-shape and up to 20 µm in length; helical shapes also occur. Colonies on MA are light yellow, convex, transparent, glistening and circular with entire margins. Gliding motility is not observed.
