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

TL;DR: It was shown that β-O-4′ ethers and the more condensed phenylcoumarans and resinols were equally susceptible to fungal breakdown, and results indicate that electron density of the 4′- O-coupled ring and local steric hindrance are important determinants of oxidative β-o- 4′ ether degradation.

Method of pulping wood chips with a fungi using sulfite salt-treated wood chips
TL;DR: In this paper, a method of making wood pulp is described, where wood is first chipped into wood chips and then treated with an amount of sulfite salt sufficient to inhibit indigenous microorganism growth.

Improved surface properties of CTMP fibers with enzymatic pretreatment of wood chips prior to refining
TL;DR: In this article, surface properties of chemithermomechanical pulp (CTMP) fibers produced from enzymatically pretreated eucalyptus wood chips prior to refining were investigated by Field Emission Scanning Electron Microscope (FE-SEM), Transmission Electron microscope (TEM) and X-ray Photoelectron Spectroscopy (XPS).
