title: Application of direct current to protect bioreactor against contamination.
abstract: Bacteria cell suspensions were sterilized by direct electric current and the cell death rate was proportional to the current. When repeated hydrolysis of casein by immobilized mycelia was done under 0.06 A of direct electric current, contaminants were inhibited while the hydrolysis was stable for more than 10 batches (250 h).
