A preliminary study was carried out to determine the feasibility of gr
owing two model fungal organisms as biofilms in bioreactors in which t
he biofilm was supported on novel capillary membranes which have no ex
ternal skin, and thus allow high transmembrane flux. The fungi used we
re Trametes versicolor and Neurospora crassa. Biofilm morphology and e
xtracellular enzyme production were monitored. The removal from the bi
oreactor feed of a model pollutant, p-cresol, by T. versicolor was inv
estigated, and results indicated that the cresol was removed from the
solution.
