摘要

Biological treatments using white-rot fungi, based in their ability to degrade lignin, can constitute an interesting approach to remove colour and toxic compounds usually contained in paper pulp effluents due to the presence of recalcitrant lignin derived molecules. In this work, strains A-137 and A-136 (IJFM collection, CIB-CSIC, Madrid) of Trameters versicolor, a ligninolytic white-rot fungus that have been frequently reported in relation to degradation of lignin, have been used for decolorization studies of the straw alkaline-pulping effluent from SAICA factory (Zaragoza, Spain). From results obtained it can be concluded that decolorization percentages about 80% can be obtained in 4-6 days (for maximum initial colour effluent between 12,000 and 15,000 CU) and total phenolic content can be reduced in about 90%. Mn-dependent peroxidase (about 20 IU/I) and high values of laccase activities (up to 700 IU/I) were produced, what may be of great interest to set up ligninolytic enzymes production processes for industrial uses.
