European Commission Consejo Superior de Investigaciones Científicas (España) Ence Energía y Celulosa Laccase-mediator Industrial biocatalysts Fungal enzymes Pycnoporus cinnabarinus Pitch Paper pulp 1Instituto de Recursos Naturales y Agrobiología, CSIC, PO Box 1052, E-41080, Seville, Spain; and 2Centro de Investigaciones Biológicas, CSIC, Ramiro de Maeztu 9, E-28040 Madrid, Spain Lipophilic extractives in wood and other lignocellulosic materials exert a negative impact in pulp and paper manufacturing causing the so-called pitch problems. In this work, the appropriateness of an enzymatic treatment using the laccase-mediator system for pitch biocontrol is evaluated. With this purpose, three pulp types representative for different raw materials and pulping processes - eucalypt kraft pulping, spruce thermomechanical pulping and flax soda-anthraquinone pulping - were treated with a high-redox potential laccase from the basidiomycete Pycnoporus cinnabarinus in the presence of 1-hydroxybenzotriazole as a redox mediator. The gas chromatography and gas chromatography/mass spectrometry analyses of the lipophilic extractives from the enzymatically-treated pulps revealed that the laccase-mediator treatment completely (or greatly) removed most of the pitch-causing lipophilic compounds present in the different pulps including: i) free and conjugated sitosterol in eucalypt paper pulp; ii) resin acids, sterol esters and triglycerides in spruce pulp; and iii) sterols and fatty alcohols in the flax pulp. Different amounts of free and conjugated 7-oxosterols were found as intermediate products in the oxidation of pulp sterols. Therefore, the laccase-mediator treatment is reported as an efficient method for removing pitch-causing lipophilic compounds from paper pulps obtained from hardwood, softwood and nonwoody plants. This study has been funded by the Spanish projects AGL2002-393 and BIO2002-1166, the EU projects QLK5-99-1357 and QLK3-99-590, and by ENCE-CSIC contracts.
