abstract：:A new fed-batch reactor was developed to conduct aerobic biodegradation studies. Its unique feature lies in the ability to self-regulate feed addition, according to the evolution of the degradation process, which is proportional to gaseous products formed, mainly CO2. The reactor is particularly well suited to evaluat...
