Over the past two decades, substantial investments have been made in engineering microorganisms to produce specific fuels and chemicals as part of the global bioeconomy. Many target molecules accumulate intracellularly, and a challenge is how to effectively extract the product from the cells without needing to destroy them due to the barrier imposed by the cell membrane. For some hydrophobic compounds, an organic overlay is an effective strategy for nondestructive product extraction, although the relationship between functional groups on the product and the rate of extraction are not well understood. Through both biased and unbiased molecular dynamics simulations for a range of fatty acyl compounds and terpenoids, we directly compute permeability coefficients for different steps of the extraction process. Via comparative analysis between the calculated permeability coefficients and observed interactions between the compounds and the membrane, we determine how the rate limiting steps vary depending on product chemistry. For instance, fatty aldehydes are found to transfer very rapidly across the membrane bilayer relative to alcohols, although their comparable rate of extraction into the organic phase makes them equally effective at extraction from the cell. In assessing the terpenoids, it is found that in general a modestly hydrophilic product improves desorption rates into an organic phase sufficiently to make up for their lower bilayer crossing rate. With this new insight, we can more effectively engineer microorganisms towards the production of these modestly hydrophilic fuel precursors or chemicals.
