Genetic Modification of Cyanobacteria to Break Down Organic Compounds and Inhibit Toxin Production

Cyanobacteria are photosynthetic bacteria commonly found in water. Microcystis aeruginosa is one such cyanobacteria that is found within the waters of Utah Lake. M. aeruginosa produces the microcystin toxin which is harmful to the aquatic life and contributes to the ongoing problem of eutrophication and, if ingested, is also harmful to humans. Alongside this toxin producing cyanobacteria, Utah Lake is contaminated with polychlorinated biphenyls (PCBs) which are highly carcinogenic chemical compounds. This study aims to offer a method of bioremediation by engineering M. aeruginosa to carry a BPH gene pathway that breaks down PCBs. Using CRISPR, this gene would remove the microcystin producing gene and replace it with the BPH gene resulting in the engineered M. aeruginosa to breakdown the PCB contaminants and halt further production of the microcystin toxin.
