Fig. 4From: A thermostable laccase from Thermus sp. 2.9 and its potential for delignification of Eucalyptus biomassFTIR spectra of LAC_2.9-treated eucalyptus biomass. Samples were treated with: a LAC_2.9; b LAC_2.9 and HBT; and c LAC_2.9 with pHBA. Dotted lines represent spectra of enzyme-treated samples. Solid lines represent spectra of equivalent no-enzyme controls treated with cellular extract of E. coliBack to article page
