Use of new endophytic fungi as pretreatment to enhance enzymatic saccharification of Eucalyptus globulus

New endophytic fungi are assessed for the first time as pretreatment to enhance saccharification of Eucalyptus globulus wood. The fungi are all laccase-producing ascomycetes and were isolated from eucalyptus trees in Spain. After five endophytes had been assayed alone or in combination with white-ro...
