Differences and dynamic changes in the cell surface properties of three Pseudomonas aeruginosa strains isolated from petroleum-polluted soil as a response to various carbon sources and the external addition of rhamnolipids.

Three Pseudomonas aeruginosa strains isolated from petroleum-polluted soil were the subject of studies concerning changes in cell surface properties. Fundamentally different reactions could be observed for each of the studied strains after a cultivation on various carbon sources. The experiments carried out during the logarithmic growth phase showed, that the changes in the cell surface hydrophobocity values were dynamic and substrate dependant.
