Analysis of ROS formation and light-driven antimicrobial efficacy of eleven LOV-based FPs. In particular, the determination of singlet oxygen (1O2) quantum yields and superoxide photosensitization activities via spectroscopic assays and performed cell toxicity experiments in E. coli. Besides miniSOG and SOPP, which have been engineered to generate 1O2, all of the other tested flavoproteins were able to produce singlet oxygen and/or hydrogen peroxide but exhibited remarkable differences in ROS selectivity and yield.

Optimization of the engineered pathway for production of D-glucaric acid, a precursor to nylons and detergents, requires strategies that manage pathway competition with glycolysis as well as the stability and activity of the rate-controlling enzyme. Two orthogonal, autonomous, and tunable dynamic regulation strategies were layered to produce the highest reported glucaric acid titers in Escherichia coli K-12 strains. The implementation of two regulatory circuits harnesses synthetic biology tools to program and optimize cellular behavior and demonstrates the power of multiplexed dynamic control for strain optimization.

This work explores using high-throughput methods, real-time data capture, and automated analysis to enhance the student learning experience in applied college-level biochemical engineering lab classes. In the past, engineering laboratory classes were structured with a pre-lab lecture, one uniform assigned experiment, and data analysis done at a later date and then reported back.
