1. A process for carrying out a biologically catalyzed reaction comprising the steps of:

  • introducing an influent solution containing reactants into the lower section of an upflow packed bed column packed with a support material for microorganisms, said support material having attached thereto anaerobic microorganisms for catalyzing the reaction of said reactants;

    introducing with said influent a membrane disruptive detergent to lyse dead microorganisms from said support and to make available the essential nutrient of said dead microorganisms to the remaining live microoganisms;

    allowing said reactants to react under the influence of said anaerobic microorganisms; and

    simultaneously with said steps of introducing and allowing restricting the presence of an essential growth nutrient within said influent solution to cause the population of said anaerobic microorganism to remain substantially constant and to prevent said anaerobic microoganisms from plugging said packed column.
