New bioactive secondary metabolite with absorption spectrum similar to red pigmented prodigiosine has been isolated from a marine bacterium Vibrio sp. The pigment extract inhibits growth of Gram positive and negative bacteria such as Bacillus subtilis, Staphylococcus epidermidis, Escherichia coli, Salmonella typhimurium, and Micrococcus luteus. Environmental factors that increase pigment production have been optimized. It has been also shown that environmental factors modulate intercellular communication and consequently pigment production.

COBISS.SI-ID: 3575928The aim of the contribution is to present the response of the novel red-pigmented Vibrio sp. isolated from the estuarine waters in the Northern Adriatic Sea to changes in environmental properties which have a crucial role in bacterial lives. We have shown that environmental factors modulate signal production by quorum sensing and consequently production of secondary metabolites.
