Schematic interpretation of the global response of bacterial consortium B in the presence of ETBE. Panel (A) represents the possible route of the ETBE metabolism followed in consortium B. Tert-butyl alcohol was identified by a GC-MS analysis, which is represented in the box. Panel (B) represents the proteins that are induced in bacterial consortium B in response to ETBE. The abundance of the protein is indicated in boxes with arrows pointing up or down to represent the more or less abundant proteins in the ETBE-induced state. Aldehyde dehydrogenase is identified in the proteomic analysis. It is believed to be involved in the ETBE metabolism and is abundant, as indicated by the arrow.
