Popis:	A highly porous nylon biocarrier was developed to support immobilized bacteria in bioreactors used to treat liquid wastes. Porosity analyses and scanning electron microscopy showed microbial colonization of accessible pores typically in the range of 100 to 1,200 (mu)m, with some as large as 3.9 mm. A bench-scale packed-bed reactor achieved a p-nitrophenol (PNP) removal rate of 5.95 kg of PNP m(sup-3) day(sup-1) for wastes containing 1,200 mg of PNP liter(sup-1). Complete mixing of the biocarrier bed to remove excess surface biomass was routinely achieved with simple air injection. These porous polymer biocarriers are promising as microbial supports in liquid-waste treatment and bioremediation applications.
