英文摘要 | Marine hydrocarbon biodegradation is an important environmental process conducted by microbes and modulated by oceanographic conditions. Following up on the patterns of petroleum hydrocarbon biodegradation observed after the Deepwater Horizon disaster, we measured respiration rates for the obligate alkane-degrading bacterium, Alcanivorax borkumensis SK2, to assess the relationship between hydrocarbon respiration rates and the phase, wax versus liquid, of the substrate. Using a matrix of temperatures (20, 25, 30, 35, and 40 degrees C) and n-alkanes (n-C-14, n-C-15, n-C-16, n-C-17, n-C-18, n-C-19, and n-C-20) for which each temperature gap spans the phase transition point of an n-alkane, we demonstrate that the n-alkane respiration rate decreases substantially when the substrate is in the wax versus liquid phase. The observed effect spans the full experimental temperature range. Subsequent experimentation with only wax-phase n-C-19 indicates that the availability of surface area modulates the n-alkane respiration rate and is likely a factor contributing to the observed respiration rates being lower for wax-phase than for liquid-phase hydrocarbons. These phase hydrocarbons are subject to biodegradation by A. borkumensis SK2 but that rates are suppressed relative to results demonstrate that wax those of liquid phase hydrocarbons. The results are consistent with interpretations of hydrocarbon biodegradation patterns from Deepwater Horizon with broader relevance to the behavior of hydrocarbons in the ocean. |
