Altered expression level of Escherichia coli proteins in response to treatment with the antifouling agent zosteric acid sodium salt

Abstract

Summary Zosteric acid sodium salt is a powerful antifouling agent. However, the mode of its antifouling action has not yet been fully elucidated. Whole cell proteome of Escherichia coli was analysed to study the different protein patterns expressed by the surface‐exposed planktonic cells without and with sublethal concentrations of the zosteric acid sodium salt. Proteomic analysis revealed that at least 27 proteins showed a significant (19 upregulated and 8 downregulated, P E. coli cells, which favours the expression of various protective proteins, the AI‐2 production and the synthesis of flagella, to escape from adverse conditions.
