MS ion abundances obtained for Triton X-100 subjected to the biodegradation tests. OPEO5-19, octylphenol ethoxylates, containing 5 to 19 ethoxy groups. Two types of test are without diesel oil (a) and with diesel oil added to the sample (b). Initial mean results obtained for the start of the tests. Rahnella sp. strain EK12, Achromobacter sp. 4(2010) and Pseudomonas stutzeri strain 9 mean results obtained after 7 days of the biodegradation with or without diesel oil for Rahnella sp. strain EK12, Achromobacter sp. 4(2010) and Pseudomonas stutzeri strain 9, respectively
