No Carbon Left Behind
22 Jun 2010 | Publications | Contributor(s): Maureen C McCann
Purdue University scientists are hoping to develop new methods of biofuel production from plantbiomass distinctly different from that used to make ethanol. The production of advanced biofuels, particularly liquid hydrocarbons, would eliminate those inefficiencies and add to the types of fuelused...

Identification of different oxygen functionalities in aromatic analytes by using negative mode electron ionization and DOE multiple collision-activated dissociation steps
27 Jun 2012 | Publications | Contributor(s): Lucas Mark Amundson, Jennifer Reece, Hilkka Inkeri Kenttamaa
A tandem mass spectrometric method using a commercial linear quadrupole ion trap (LQIT) mass spectrometer and another LQIT coupled with a Fourier transform ion cyclotron resonance (FT-ICR) mass spectrometer is described for the identification and counting of different oxygen-containing...
Elucidating the role of ferrous ion cocatalyst in enhancing dilute acid pretreatment of lignocellulosic biomass
01 Oct 2012 | Publications | Contributor(s): Hui Wei, Bryon Donohoe, Peter Ciesielski, Shi-You Ding, Mike Himmel, Melvin Tucker
Background: Recently developed iron cocatalyst enhancement of dilute acid pretreatment of biomass is a promising approach for enhancing sugar release from recalcitrant lignocellulosic biomass. However, very little is known about the underlying mechanisms of this enhancement. In the current...
Identification of epoxide functionalities in protonated monofunctional analytes by using ion/molecule reactions and collision-activated dissociation in different ion trap tandem mass spectrometers
13 Sep 2013 | Publications | Contributor(s): Fanny Widjaja, Hilkka Inkeri Kenttamaa
A mass spectrometric method has been delineated for the identification of the epoxidefunctionalities in unknown monofunctional analytes. This method utilizes gas-phase ion/molecule reactions of protonated analytes with neutral trimethyl borate (TMB) followed by collision-activated dissociation...
The Effect of Axial Ligand on the Oxidation of Syringyl Alcohol by Co(salen) Adducts
13 Sep 2013 | Publications | Contributor(s): Joseph J Bozell, Diana Cedeno
Experimental work on the oxidation of the lignin model, syringyl alcohol, using oxygen and a Co(salen)catalyst has revealed variations in yield with different imidazole-based axial ligands. A reasonable linear relationship was found between product yield and pKa of the axial ligand. The current...
Simultaneous catabolism of plant-derived aromatic compounds results in enhanced growth for members of the Roseobacter lineage
13 Sep 2013 | Publications | Contributor(s): Alison Buchan
Plant-derived aromatic compounds are important components of the dissolved organic carbon pool in coastal salt marshes, and their mineralization by resident bacteria contributes to carbon cycling in these systems. Members of the roseobacter lineage ofmarine bacteria are abundant in coastal salt...
Envisioning the transition to a next-generation biofuels industry in the Midwest
13 Sep 2013 | Publications | Contributor(s): Nicholas C Carpita, Nathan Mosier, Wendy Peer, Angus Murphy, Maureen C McCann
Corn grain ethanol production is a mature industry built on a Midwestern agricultural infrastructure. Second- and third-generation biofuels and bio-based products industries could take advantage of this robust framework. Signifi cant but not insurmountable barriers remain for grower acceptance...
Characterization of model compounds of processed lignin and the lignome by using atmospheric pressure ionization tandem mass spectrometry
13 Sep 2013 | Publications | Contributor(s): Laura Jane Haupert, Ben Owen, Christopher Louis Marcum, Tiffany Mae Jarrell, Lucas Mark Amundson, Padmaja Narra, Sabir Aqueel, Trenton Parsell, Mahdi Abu-Omar, Hilkka Inkeri Kenttamaa
In the search for alternatives to fossil fuel and the valuable chemicals now derived from crude oil, lignocellulosic biomass has attracted wide interest. Degradation of the cellulose and lignin components of the biomass results in complex mixtures. Hence, the ability to identify the products of...
The Plant Actin Cytoskeleton Responds to Signals from Microbe-Associated Molecular Patterns
13 Sep 2013 | Publications | Contributor(s): Jessica Lynn Henty, Chris Staiger
Plants are constantly exposed to a large and diverse array of microbes; however, most plants are immune to the majority of potential invaders and susceptible to only a small subset of pathogens. The cytoskeleton comprises a dynamic intracellular framework that responds rapidly to biotic stresses...
