Biochemical Composition And Modes Of Substrate Uptake To Alkane-Grown

Abstract

The variation of the relative amounts of proteins, carbohydrates and lipids quantified from cells and supernatants of a marine bacterium Pseudomonas nautica strain 617, was a response to changes in growth substrates (acetate or eicosane). Modes of substrate uptake: adherence, emulsification and solubilization depend of its biochemical composition. The enchancement of extracellular compounds produced during the growth on eicosane. The solubilizing, emulsifying activities as well as their adherence were observed in relation to the biochemical changes. The biodegradation percentage of eicosane is 59% in 3.5 days-old culture.
