13. (10 pts) 1,4-dioxane (CaH&O:) is an emerging contaminant in groundwater. A bacterium Pseudonocardia dioxanivorans CB1190 can oxidize 1,4-dioxane as the sole energy and carbon source. Determine the true cell yield (Y) of CB1190 growing aerobically on 1,4-dioxane. The Standard Gibbs Energy of formation (G) of 1,4-dioxane is -200 kJ/mol. Assume pH = 7, the energy transfer efficiency is 0.5, and this bacterium utilizes ammonium as the nitrogen source.
