Overcoming TCE Cometabolism Rate Limits
Aerobic cometabolism of TCE may be limited by the potential microbial toxicity of by products or by product metabolic repression. An independent comparison of induced cometabolism using soluble methane and CL-Out bioaugmentation showed that CL-Out bioaugmentation removed more TCE. The TCE removal rate by CL-Out when supplemented with an oxygen source was a steady rate that continued past apparent limits of induced cometabolism. The significant difference may be in that the population of beneficial microbes that can be added is much higher than the population level that may be achieved through biostimulation.
