Building on the DCM-degradation pathway of M. extorquens DM4, our project is driven and refined by the <font style="font-weight:700;">dialogue</font> between modelling simulations and experimental data. We are expressing intracellular microcompartments to accelerate and contain the reaction, preventing accumulation of toxic intermediates, while maximising the sensitivity and catalytic efficiency of the system through directed evolution. We are additionally constructing a synthetic fluorescent biosensor and incorporating our engineered bacteria into diffusion-limiting biopolymeric beads to ensure safety, efficiency and ease of use.<br><br>

Inspired by the DCM degradation pathway of M. extorquens DM4, our project is driven and refined by the dialogue between modelling simulations and experimental data. Bioremediation is optimised by expressing the DCM degrading system in host strains along with microcompartments to accelerate the reaction and minimise toxic intermediates. Our biosensor is tuned to our characterisation and improvements of the catalytic efficiency of the system, while incorporation of the bacteria into novel diffusion-limiting biopolymeric beads ensures safe and rapid degradation.
