Mechanism Of Lignin Inhibition Of Enzymatic Biomass Deconstruction, Josh V. Vermaas, Loukas Petridis, Xianghong Qi, Roland Schulz, Benjamin Lindner, Jeremy C. Smith

Faculty Publications and Other Works -- Biochemistry, Cellular and Molecular Biology

Background

The conversion of plant biomass to ethanol via enzymatic cellulose hydrolysis offers a potentially sustainable route to biofuel production. However, the inhibition of enzymatic activity in pretreated biomass by lignin severely limits the efficiency of this process.

Results

By performing atomic-detail molecular dynamics simulation of a biomass model containing cellulose, lignin, and cellulases (TrCel7A), we elucidate detailed lignin inhibition mechanisms. We find that lignin binds preferentially both to the elements of cellulose to which the cellulases also preferentially bind (the hydrophobic faces) and also to the specific residues on the cellulose-binding module of the cellulase that are …

High Pressure Vibrational Properties Of Ws2 Nanotubes, Kenneth Robert O'Neal, J G. Cherian, A Zak, R Tenne, Janice L. Musfeldt

Chemistry Publications and Other Works

We bring together synchrotron-based infrared and Raman spectroscopies, diamond anvil cell techniques, and an analysis of frequency shifts and lattice dynamics to unveil the vibrational properties of multiwall WS2 nanotubes under compression. While most of the vibrational modes display similar hardening trends, the Raman-active A1g breathing mode is almost twice as responsive, suggesting that the nanotube breakdown pathway under strain proceeds through this displacement. At the same time, the previously unexplored high pressure infrared response provides unexpected insight into the electronic properties of the multiwall WS2 tubes. The development of the localized absorption is fit to a percolation model, indicating …

How Chip Size Impacts Steam Pretreatment Effectiveness For Biological Conversion Of Poplar Wood Into Fermentable Sugars, Jaclyn D. Demartini, Marcus Foston, Xianzhi Meng, Seokwon Jung, Rajeev Kumar, Arthur J. Ragauskas, Charles E. Wyman

Faculty Publications and Other Works -- Chemical and Biomolecular Engineering

Background

Woody biomass is highly recalcitrant to enzymatic sugar release and often requires significant size reduction and severe pretreatments to achieve economically viable sugar yields in biological production of sustainable fuels and chemicals. However, because mechanical size reduction of woody biomass can consume significant amounts of energy, it is desirable to minimize size reduction and instead pretreat larger wood chips prior to biological conversion. To date, however, most laboratory research has been performed on materials that are significantly smaller than applicable in a commercial setting. As a result, there is a limited understanding of the effects that larger biomass particle …

Protective Effect Of Anti-Suam Antibodies On Streptococcus Uberis Mastitis, Raúl A. Almeida, Oudessa Kerro Dego, María E. Prado, Susan I. Headrick, Mark J. Lewis, Lydia J. Siebert, Gina M. Pighetti, Stephen P. Oliver

Animal Science Publications and Other Works

In the present study, the effect of anti-recombinant Streptococcus uberis adhesion molecule (SUAM) antibodies against S. uberis intramammary infections (IMI) was evaluated using a passive protection model. Mammary quarters of healthy cows were infused with S. uberis UT888 opsonized with affinity purified anti-rSUAM antibodies or hyperimmune sera. Non-opsonized S. uberis UT888 were used as a control. Mammary quarters infused with opsonized S. uberis showed mild-to undetectable clinical symptoms of mastitis, lower milk bacterial counts, and less infected mammary quarters as compared to mammary quarters infused with non-opsonized S. uberis. These findings suggest that anti-rSUAM antibodies interfered with infection of …

Exploring Rapid Radiochemical Separations At The University Of Tennessee Radiochemistry Center Of Excellence, Howard L. Hall, John D. Auxier Ii

Faculty Publications and Other Works -- Institute for Nuclear Security

The University of Tennessee formed its Radiochemistry Center of Excellence (RCoE) in 2013 with support from the U.S. National Nuclear Security Administration. One of the major thrusts of the RCoE is to develop deeper understanding of rapid methods for radiochemical separations that are relevant to both general radiochemical analyses as well as post-detonation nuclear forensics. Early work has included the development and demonstration of rapid separations of lanthanide elements in the gas phase, development of a gas-phase separation front-end for ICP-TOF-MS analysis, and the development of realistic analytical surrogates for post-detonation debris to support methods development.
