Biological treatment of waste water containing a large amount of phenol was carried out by using a phenolassimilating fungus,Aureobasidium pullulans No. 14 adhered (“semi-immobilized”) to fibrous asbestos. The column reactor employed for oxidative degradation of phenol consisted of a cylindrical glass column containing plastic nets.

During 27 days operation, it was observed that: 1) The phenol removal capacity of the reactor gradually increased during the first 10 days, reaching a stable level. 2) The best phenol removal capacity (50 mg phenol removed/h/ liter of reactor volume) was obtained when an artificial waste water containing up to 1,200 μg/ml phenol was applied to the reactor. 3) Much higher concentrations of phenol (e.g. 1,700 μg/ml) brought about a marked decrease in the phenol removal capacity (40–50 mg/h/liter). 4) Satisfactorily stable operation was achieved using the semiimmobilized mycelia ofAureobasidium pullulans, whose active state could be checked by observing the thick, black-colored biomass which is characteristic of the genusAureobasidium and covered the plastic nets inside the glass column reactor.
