The paper develops an enzyme-level benchmark using bacterial laccases to predict the biotransformation of trace organic contaminants in water.

This study investigates the effects of treated wastewater on stream biofilm resistomes, identifying a new planctomycete beta-lactamase that is functionally active despite low sequence similarity to known ARGs.

This study identifies substrate promiscuity in DEET hydrolases from stream biofilms exposed to treated wastewater, showing broad enzymatic activity across multiple contaminants.
