[Concentration and method of cadmium fixation by a marine Vibrio].
In many organisms, intracellular fixation of cadmium involves specific proteins, the metallothioneins. A similar phenomenon was demonstrated in a marine bacterium belonging to the genus Vibrio. The accumulation of the metal is a function of its concentration in the medium. The uptake is also increased by cysteine, which decreases the toxicity of the metal.
