I. INTRODUCTION
Sanitary landfill leachate is a highly polluted and
complex wastewater. Its quality is the result of biological,
chemical and physical processes in landfills combined with
the specific waste composition and the landfill water regime
[1]. Biological treatment is the most common practice for
leachate treatment worldwide but the remaining values of
COD and adsorbable organic halogenated compounds (AOX)
are still relatively high [2]. With increasing leachate effluent
quality standards the efforts for leachate treatment also
increase.
White-rot basidiomycetous fungi have been implicated in
the transformation of a large amount of organopollutants
structurally related to lignin [3], [4]. Besides that, the use of
