[Antibiotics from basidiomycetes, VI. Merulinic acids A, B, and C, new antibiotics from Merulius tremellosus and Phlebia radiata (author's transl)].
Three new antibiotics, merulinic acids A, B, and C, have been isolated from fruiting bodies of Merulis tremellosus and Phlebia radiata. They are closely related derivatives of beta-resorcylic and salicylic acid, carrying monounsaturated C17-alkyl side chains in 6-position. The merulinic acids are mixtures of the delta8'-compounds with minor amounts of the corresponding delta10'-, dehydro, and d...
متن کاملEucalyptus globulus wood fractionation by autohydrolysis and organosolv delignification.
This work provides an assessment on the fractionation of Eucalyptus globulus wood by sequential stages of autohydrolysis (to cause the solubilization of hemicelluloses) and organosolv pulping (to dissolve lignin, leaving solids enriched in cellulose). With this approach, valuable products (hemicellulose-derived saccharides, sulphur-free lignin fragments and cellulosic substrates with low conten...
متن کاملConversion of milled pine wood by manganese peroxidase from Phlebia radiata.
Purified manganese peroxidase (MnP) from the white-rot basidiomycete Phlebia radiata was found to convert in vitro milled pine wood (MPW) suspended in an aqueous reaction solution containing Tween 20, Mn(2+), Mn-chelating organic acid (malonate), and a hydrogen peroxide-generating system (glucose-glucose oxidase). The enzymatic attack resulted in the polymerization of lower-molecular-mass, solu...
متن کاملSelection of White-rot Fungi for Biopulping*
Different rates of wood decay and ligninolytic activity were found in wood decayed by various white-rot fimgi. Chemical and ultrastructural analyses showed wood decayed by Coriolus versicolor consisted of a nonselective attack on all cell wall components. Lignin degradation was restricted to the cell wall adjacent to hyphae or around the circumference of cell lumina. Decay by Phellinus pini, Ph...
متن کاملElectrochemical Delignification of Wood Pulp Using Polyoxometalate Mediators
It has been found that polyoxometalates (POMs) can act as mediators in the electrochemical oxidation of lignin in pulps. An electrochemical cell, with a Nafion membrane separating the anode and cathode compartments, was used in the delignification experiments. A softwood kraft pulp was placed in the anode compartment with a buffered 0.01M solution of the polyoxometalate Na5[SiVW11O40]. During e...
