Towards Developing Anaerobic Digestion Based Biorefinery – Research On Food Wastes As Feedstock
Oct 19, 2011
Shulin Chen
Anaerobic digestion (AD) is a proven technology for waste treatment. However, as the organic material becomes more valuable and being treated as resources, traditional AD process is no longer adequate. The Bioprocessing and Bioproduct Engineering Laboratory at Washington State University has been...
BIOCORE - On a Paradigm for the Design and Synthesis of Real-Life Biorefineries
Oct 19, 2011
Aikaterini D. Mountraki
As oil is a fast depleting resource (BP, 2010), much is expected by the production of biofuels as valid options to replace fossil-oil transportation fuels. Biorefineries are not an entirely new concept. Many of the traditional biomass conversion technologies such as the sugar and paper industries...
Simultaneous Extracellular Polymeric Substance (EPS) and Lipid Production by Activated Sludge Via Fermentation of Glucose
Oct 19, 2011
Patrisha J. Pham
The use of activated sludge microflora to convert sugars, derived from the hydrolysis of lignocellulose biomass, into lipids for biofuel production is of current research interest in our group. Lipid accumulation in this system has been enhanced by manipulating the carbon-nitrogen (C:N) ratio and...
Effect of Steam Explosion On Degradability and Accessiblity of Loblolly Pine In Bioethanol Applications
Oct 19, 2011
Yuzhi Kang
Abstract Among the various biomass pretreatment methods, steam explosion is one of the most widely used due to its cost-effective disruption of the plant structure and hence enhanced enzymatic accessibility. The operational parameters including temperature, residence time and acid concentration...
Change of Structure of Corncob with Dilute Acid and Lime Pretreatment and a Potential Process for Xylose Co-Production of Cellulosic Ethanol
Oct 19, 2011
Jihong Li
Degree of polymerization (DP) of cellulose is considered an important factor to effect on the conversion of Lignocellulose. The higher DP of cellulose, the more difficult conversion of lignocellulose is. In this study, corncobs were pretreated with dilute acid process for production of xylose, and...
Incremental Disassembling of Woody Biomass and Production of Biochemicals
Oct 19, 2011
Shijie Liu
Woody biomass is a reliable renewable source of raw materials for energy and chemicals. Woody biomass is structurally composed of cellulose, lignin, hemicelluloses and other minor components. The compositions vary from species to species. The complexity / heterogeneity of woody biomass presents...
The Role of Cellulose Accessibility On Enzymatic Saccharification of Lignocelluloses
Oct 19, 2011
Junyong Zhu
So much research has been dedicated to understand the effects of various factors on enzymatic hydrolysis of lignocelluloses. It has been understood that removal of hemicelluloses is very important to improve lignocellulosic substrate digestibility. It has also been identified that improving enzyme...
Membrane Filtration of Lignocellulosic Hydrolyzates: Comparison of Crossflow and Dead-End Microfiltration
Oct 18, 2011
Bhavin Bhayani
Depleting oil reserves have encouraged the development of technologies to harness the natural resources to sustain the energy needs. Renewable lignocellulosic biomasses have been focus of many studies but advances in the purification and recovering of the products from the product medium has been...
Acetic Acid Removal From the Hydrolysate Using Reactive Extraction In a Membrane Extractor/Reactor
Oct 18, 2011
Rahul Patil
Production of bioethanol from lignocellulosic biomass requires pretreatment of the biomass to hydrolyze hemicellulose, separate lignin and reduce cellulose crystallinity. During the pretreatment by dilute acid hydrolysis, several grams of acetic acid per liter of hydrolysate is generated. Acetic...

Cellulose Extraction From Rice Hulls Using Ionic Liquids
Oct 18, 2011
Charles J. Coronella
Over one fifth of calories consumed by humanity are from rice. Consequently, vast quantities of rice hulls are disposed of as waste, since the hull constitutes 20% of rice mass. Standard practice for disposal of rice hulls is burning, generating pollution and CO 2 , or thrown away in vast...
Cellobiose Hydrolysis Using Acid-Functionalized Nanoparticles
Oct 18, 2011
Leidy Peña
Mineral acids have been used effectively for the pretreatment of cellulosic biomass to improve sugar recovery and promote its conversion to ethanol; however, substantial capital investment is required to enable separation of the acid, and corrosion-resistant materials are necessary. Disposal and...
Point of Use Recyclable Bioreactor System for Bio-Agricultural Applications
Oct 18, 2011
Matthew A. Robinson
Farmers have long been respected for their self-sufficiency, acting as primary producers for society. Yet as time progresses, productivity demands drive farmers to require increasing levels of technology in terms of seed strains, fertilizers and pesticides in order to remain competitive. In turn...
Effect of Column Temperature On HPLC Separation of Acetic Acid and Levulinic Acid
Oct 18, 2011
Rui Xie
High performance liquid chromatography (HPLC) is a routine method in the analysis of degradation products in the prehydrolysate or the hydrolysis liquor of lignocellulosic biomass. Cation exchange column chromatography with a metal counter ion has been used for the quantitative analysis of...
