Impact of styrene, 1-hexene, and 1-octene on cell growth. A: The indicated concentrations of olefin compounds were added to an E. coli K12 culture at an OD₆₀₀ = 0.2. OD was monitored after 2 h at 37 °C. The bars on the two first panels represent standard deviation between duplicates. B: A survival test in presence of 1-octene was performed. Six different dilutions of a culture (10 cells to 10⁷ cells, left to right) of E. coli K12 were spotted in triplicate on an agar plate. An overlay of 1-octene was added over the cells (control had no overlay). Plates were incubated at room temperature for 2 days, and the lid of the petri-dishes were removed for recording images.
