✦ Synopsis
Pretreatment of Kraft pulp mill effluents by mycelial pellets or extracellular ligninolytic liquid from
Phanerochaete chrysosporium enhanced the anaerobic degradation of high molecular weight (HMW) compounds up to 79% and 72% respectively, against 45% when only anaerobic digestion was considered. Decolourization was obtained only after fungal pretreatment, since both anaerobic digestion and ligninolytic liquid pretreatment of Kraft effluent slightly increased colour.
INTRODUC~ON
Anaerobic digestion has become one of the most extensively employed treatments for many types of forest industry effluents (Lettinga et al. 1991; FernAndez et al. 1995), although their application to black liquors and bleaching effluents treatment present some specific limitations. The carbon oxygen
