Microbial communities contain densely packed cells where competition for space and resources are fierce. These communities are generally referred to as biofilms and provide advantages to individual cells against immunological and antimicrobial intervention, dehydration, and predation. High intracellular pools of cyclic diguanylate monophosphate (c-di-GMP) cause cells to aggregate during biofilm formation through the production of diverse extracellular polymers. Genes that encode c-di-GMP catalytic enzymes are commonly mutated during chronic infections where opportunists display enhanced resistance to phagocytosis and antibiotics. Our lab uses an emergent multicellular trait in the model organism Pseudomonas fluorescens Pf0-1 to study the emergence of c-di-GMP mutations …

Undergraduate Distinction Papers
Streptomyces is a genus of the phylum actinobacteria most commonly found as soil bacteria and used as a major source of antibiotics. RmdA and RmdB are phosphodiesterases that break down the ubiquitous second messenger cyclic-di-GMP which determines colony morphology and development of Streptomyces. The objective of this research is to identify whether RmdA will have interactions with itself using the Bacterial Adenylate Cyclase Two-Hybrid (BACTH) System. Each gene was fused into one of two BACTH vectors that encode a different domain of a single protein (T18 and T25) and then cotransformed into the BACTH indicator strain. The transformants were …
