This study examined the biodegradation of phenol by Ralstonia eutropha in a Kissiris- immobilized cell bioreactor (ICB), operated in a repeated batch recycling mode.. The steady biodegradation rate of 23.7 mg/g/h, over a wide range of the initial phenol concentrations up to 1400 mg/L in the ICB, indicated an increased tolerance limit of the Kissiris-immobilized cells towards phenol. Both Haldane and Luong substrate inhibition models were used to describe biodegradation kinetic of free cells system. The Haldane equation gave the following values for the biokinetic parameters: μmax =  0.36 h−1, KS =  40.48 mg/L, and Ki =  181.9 mg/L. However, according to the Luong model, these parameters were μmax =  0.23 h−1, KS =  24.8 mg/L, Sm =  1018 mg/L, and n =  1.3. By following appropriate operational conditions and use of the ICB, it was found to be possible to extend the efficiency of the highly porous structure of the siliceous mineral Kissiris in cell immobilization. This holds significant promise for pollutant biodegradation issues.
