Resumen:
Lignocellulosic
material represents the largest source
of renewable energy
and organic matter of the
biosphere. Its structure and
composition determines industrial
use and its possible application
in biotechnology. The white rot fungi (WRF), because of their oxidative and hydrolytic enzymes secretion capacity and distribution, are lignocellulolytic organisms par
excellence. The Atlantic Forestor Selva Paranaense,
one of the most biodiverse subtropical
ecoregions in the planet, is comprised within Atlantic
Forest or Atlantic ecoregion complex, so it has great potential for exploration and description of new microorganisms that can reveal innovative capabilitiesfor potential biotechnological
applications, area where WRF play an essential role. The aim of our work was to
search and isolate WRF, to develop a pool of interest native strains for different industrial applications, such as
bioethanol production, pulp and paper industries and bioremediation, among
others. Basidiocarps were collected from decaying wood, of different natural ecosystems in Misiones.Samples were stored and transported to the laboratory, where in vitro pure cultures were obtained. It was possible to develop a strain collection of 30 isolated native
WRF strains and to keep them under
controlled conditions. This
environment will assure stability and genetic and
physiological viability, which will allow subsequenttesting for selection in different biotechnological applications.
