Biomechanical Pulping of Loblolly Pine Chips with Selected White-Rot Fungi
TLDR
Based on energy savings and improvements in the strength properties, regardless of bioreactor type, the white-rot fungus Ceriporiopsis subvermispora appeared to be superior to the otherwhite-rot fungi tested.Abstract:
Paper optical properties handsheets, whereas brightness and light scattering coefficient of the handsheets were decreased after all of the fungal treatments. Opacity of the handsheets after the fungal treatments remained unchanged. Loblolly pine (Pinus taeda) White-rot fungi Based on energy savings and improvements in the strength properties, regardless of bioreactor type, the white-rot fungus Ceriporiopsis subvermispora appeared to be superior to the other white-rot fungi tested. When incubated in stationary tray bioreactors, C. subvermispora caused only 6% weight loss, saved 42% energy during fiberization and refining, improved burst index by 32% and tear index by 67%, as compared to the control.read more

Process for producing biokraft pulp from eucalyptus chips
TL;DR: In this article, a method for producing paper pulp for use in the making of paper from eucalyptus wood chips was proposed, which comprises inoculating wood chips with white rot fungi, fermenting the wood chips so as to cause a propagation of the fungus through the wood chunks and allowing the fungus to modify the lignin, and pulping the degraded wood chips by a kraft process.
