Marinobacterium Explained

Marinobacterium is a genus of bacteria found in sea water.^[1] ^[2] The cells are rod-shaped and are motile by using one polar flagellum. S.I. Paul et al. (2021) isolated, characterized and identified two species of Marinobacterium (Marinobacterium coralli, Marinobacterium maritimum) from marine sponges of the Saint Martin's Island Area of the Bay of Bengal, Bangladesh.
