Resumen:
White-rot fungi are key regulators of the global
C-cycle; they are so far unique in their ability
to complete degrade all components of our
principal renewable resource, lignocellulose.
These filamentous wood decay fungi, common
inhabitants of forest litter and fallen trees, can
attack all the wood components, the lignin as well
as the polysaccharides. They produce an impressive
array of enzymes (cellulases, hemicellulases,
pectinases and ligninases) with potential in a wide
range of biotechnological applications, including
hazardous waste remediation and in the industrial
processing of paper and textiles. Interest in these
fungi has increased during the past two decades
spurred by the ability of these organisms to
degrade a wide variety of hazardous compounds
(including polychlorinated biphenyls, pesticides,
explosives, polycyclic aromatic hydrocarbons and
industrial dyes). To be able to use the white rotters
in these processes it is necessary to learn how their
enzymes are secreted, how they operate and under
what conditions they are active. Our current
research is focused on these subjects, and in the
screening of new isolates for their ability to
degrade xenobiotics, in the search of more
efficient strains.
