The bacterium Komagataeibacter rhaeticus has the ability to naturally produce bacterial cellulose (BC) which possesses many unique, highly useful properties suitable for a wide range of applications. We hypothesize that an optogenetic circuit in an engineered strain of K. rhaeticus grown in an optimized bioreactor can spatially control attachment of proteins to the surface of BC membranes to enable fine-tuning of these properties for different applications.
Project Abstract: Synthesizing Factor C, a protein responsible for starting the coagulation cascade in LAL testing, into B. subtilis as an alternative towards the biomedical standard of bleeding horseshoe crabs for their amoebocytes. Afterwards, designing a detection mechanism to detect and signal for the presence of endotoxin once Factor C is cleaved.

Project Abstract: Transferring genes responsible for producing PCB-dechlorinating enzymes from the anaerobic D. mccartyi bacterium, in which they are naturally found, into E.coli, an easier-to-work-with bacterium.
