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

Assessment of wood degradation by Pycnoporus sanguineus when co-cultured with selected fungi
TL;DR: The results indicated that the yeasts had no effect on degradation of E. grandis wood chips by P. sanguineus, while the presence of A. flavipes impacted on the chemical composition of the residual wood chips.

Synthetic Lignin Mineralization by Ceriporiopsis subvermispora Is Inhibited by an Increase in the pH of the Cultures Resulting from Fungal Growth
Julio C. Tapia,R Vicuna +1 more
TL;DR: C-synthetic lignin mineralization by the basidiomycete Ceriporiopsis subvermispora occurs at the highest rate in liquid cultures containing 1% glucose and a growth-limiting amount of ammonium tartrate, and (sup14)CO(inf2) evolved more rapidly from those with pH values near the optimum for MnP activity.

Enzymatic Treatment with Manganese Peroxidase from Phanerochaete chrysosporium for Enhancing Wheat Straw Pulp Characteristics
Jean-Claude Sigoillot,Michel Petit-Conil,Katia Ruel,Serge Moukha,Jean Comtat,Chantal Laugero,Jean-Paul Joseleau,C. de Choudens,M. Asther +8 more
TL;DR: Two wheat straw pulps (Kraft pulp and Chemimechanical pulp) were treated with a crude enzymatic extract containing mainly manganese dependent peroxidase, which substantially enhanced the physical properties of the pulps in all the cases studied.

Biomechanical pulping of aspen chips: energy savings resulting from different fungal treatments
TL;DR: It is reported that four-week-long treatment with white-rot fungi in a stationary wire tray bioreactor resulted in at least 35% energy savings for pulping chips to 100 mL CSF in a 300-mm-diameter disc refiner.
