Biological treatability of pulping effluents by using a Penicillium species

Pulp and paper plants are among the most polluter industries. Their effluents are normally treated biologically for standard parameters such as BOD and GOD; but biological treatment is usually not complete. Unconventional parameters unique to these wastes, such as color and organic halides(AOX), are virtually persistent throughout the treatment cycle. A fungus, which is able to affect over 50% AOX and color removal from soft wood pulping bleachery effluents in less than two days of contact, have been isolated and tentatively identified as Penicillum sp
