Vibrio natriegens is a Gram-negative marine bacterium. It was first isolated from salt marsh mud. It is a halophile or salt-loving organism requiring approximately 2% NaCl for growth. It reacts well to the presence of sodium ions which appear to stimulate growth in Vibro species, stabilise the cell membrane, affect sodium dependant transport and mobility. Under optimum conditions it grows very quickly. In the laboratory the growth media can be easily changed thus affecting the growth rate of a culture. V. natriegens is commonly found in estuarine mud.
