Creating a biodegradable drone will reduce collateral waste, lightening the footprint of unmanned science missions on planetary environments and microecosystems. Since we are using BCOAc for the construction of our drone, we plan on transforming E. coli with two genes obtained from Niesseria sicca, which synthesizes enzymes capable of degrading BCOAc; the first gene is an esterase which deacetylates the BCOAc, and the second is endo-1,4-beta-glucanase, a cellulase which speeds BC degradation. In order to trigger the onset and spread of degradation, we are investigating pressure-sensitive promoters (to simulate impact) and time-sensitive promoters linked to bacterial quorum sensing machinery. Quorum sensing allows the signal for degradation to spread to surrounding cells, enabling the complete breakdown of our biomaterials from a single point of impact.
