Area of Science:

Environmental Microbiology
Bioremediation
Machine Learning Applications

Background:

Chlorinated organic pollutants (COPs) contaminate environments, posing risks to ecosystems and human health.
Microbial electrorespiration offers a sustainable solution for COP remediation by using bacteria to drive reductive dechlorination.
Aquifer conditions present complex challenges, including spatial variability and slow reaction rates, hindering traditional remediation efforts.

Purpose of the Study:

To develop a machine learning framework for rapid optimization of bioelectrically enhanced reductive dechlorination.
To identify key environmental variables, microbial communities, and electrochemical properties influencing dechlorination rates.
To enable inverse design for determining optimal conditions for efficient COP remediation.

Main Methods:

Integrated experimental design with cathodic biofilm data analysis using machine learning models (e.g., extreme gradient boosting, random forest, multilayer perceptron).
Trained models on literature-derived datasets to uncover interrelationships between variables and dechlorination kinetics.
Employed inverse design to predict optimal parameters for dechlorinating specific COPs.

Main Results:

Identified temperature and cathode potential as primary drivers for experimental design.
Highlighted key microbial genera (e.g., *Clostridium*, *Dehalococcoides*, *Geobacter*) involved in dechlorination.
Achieved reaction rate predictions with less than 6% error for representative COPs like tetrachloroethene and trichloroethene.

Conclusions:

The machine learning framework significantly accelerates the optimization of bioelectrodechlorination processes.
This data-driven strategy enhances efficiency, reduces costs, and speeds up bioremediation compared to traditional methods.
The approach facilitates the scalable application of microbial electrorespiration for COP-contaminated water remediation and broader bioelectrochemical applications.
