Monitoring In Situ Microbial Growth and Decay in Soil Column Experiments by Induced Polarization

Real-time monitoring of the microbial activity in porous media faces considerable challenges because conventional analytical procedures are intrusive. Induced polarization has shown promises as a non-intrusive approach for such processes. However, quantitative analysis soil column experiments to show how IP-based parameters can be related density bacteria is still lacking. The evolution bacterial and induced was performed soil-packed using Pseudomonas aeruginosa O1. A relationship between quadrature conductivity established further applied assess growth decay, infer Monod kinetic parameters. inferred from mimicking field conditions were different those obtained batch experiments.
