The marine bacterium Rhodovulum sulfidophilum is a nonsulfur phototrophic bacterium, which is known to produce extracellular nucleic acids in soluble form in culture medium. In the present paper, constructing the response regulator ctrAdeficient mutant of R. sulfidophilum, we found that this mutation causes a significant decrease in the extracellular DNA production. However, by the introduction of a plasmid containing the wild type ctrA gene into the mutant, the amount of extracellular DNA produced was recovered. This is the first and clear evidence that the extracellular DNA production is actively controlled by the CtrA in R. sulfidophilum.
