Proteomic insights into Oleidesulfovibrio alaskensis G20 biofilms under copper stress


ABSTRACT: The current research evaluates the influence of Cu ions on biofilm formation on glass surface by the Oleidesulfovibrio alaskensis G20 (OA-G20) in a lactate-C medium supplemented with 30uM Cu ion. When exposed to media containing high levels of Cu ions, OA-G20 exhibited inhibited growth in its planktonic state. Whereas under the same experimental conditions, OA-G20 displayed enhanced biofilm formation on glass surfaces. To elucidate the molecular mechanisms underlying this adaptation, we performed a comparative proteomic analysis of OA-G20 stress-induced biofilms vs. control and their respective extracellular fractions.
