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...

Biofuels Manufacturing: From Feedstocks to Manufacturing and End-Product Quality Control

Oct 19, 2011

Jose Menezes

Biofuels quality is related to the inherent of feedstock materials (RMs) and operating conditions used in their production. However to be used as fuel in engines biofuels must meet certain specifications regulated by ASTM or EN standards regardless of the manufacturing processes and / or the type...

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...

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...

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...

Heterogeneous Catalysts in the Dehydration of Fructose to HMF

Oct 18, 2011

Sylvia Reiche

Several crucial steps in the upgrading of biomass-derived raw materials involve acid catalyzed reactions, such as the hydrolysis of cellulose or the dehydration of sugars. Although heterogeneous catalysts are desired in large scale industrial processes, their application is limited by several...

Reducing Process Complexity for Cellulosic Ethanol

Oct 18, 2011

L.O. Ingram

Much of the process complexity and high capital costs associate with cellulosic ethanol (dilute acid hydrolysis as a pretreatment and enzymatic saccharification of cellulose) results from side products such as furfural, acetate, and soluble lignin compounds that inhibit the biocatalysts. Inhibitor...

Co-Utilization of Methane In Steam-Biomass Gasification Using Concentrated Solar Energy

Oct 18, 2011

Aaron W. Palumbo

Presented is a novel gasification application where biomass is steam-gasified and natural gas is steam-reformed simultaneously in a solar reactor. Solar-driven gasification is a proven technology, and can augment the biofuel industry as a domestic fuel source. Gasification performed in an...

Biomimicry of the Fungal Consolidation of Biomass Pretreatment with Saccharification

Oct 18, 2011

Justin T. Kaffenberger

Efficient breakdown of ligno-cellulosic material prior to fermentation for bio-fuel production is a key step in optimizing bio-fuel production. Current industrial practice involves chemical pretreatment and acid or enzymatic saccharification to prepare ligno-cellulosic biomass for fermentation. The...

The Role of Oxygen In the Stability of Biomass Pyrolysis Oils

Oct 18, 2011

Foster Agblevor

One of the major challenges in the conversion of biomass pyrolysis to high value products and fuels is the poor stability of the oils. Biomass pyrolysis oils have shown increases in viscosity during storage at ambient conditions and when heated above ambient temperature. The poor stability of the...

The Production of Fuel Grade Butanol From Algal Carbohydrates Utilizing a Hybrid Biological and Chemical Process

Oct 18, 2011

Thomas M. Potts

Butanol has the potential to become a superior renewable fuel, either as a mixture with petroleum derived gasoline or as a stand-alone, neat fuel. The promise of butanol is currently marred by the relatively high cost of production. This paper explores a new and novel approach to the production of...

Alkaline Deacylation of Corn Stover to Reduce Toxicity of Prehydrolyzates and Improve Enzymatic Hydrolysis

Oct 18, 2011

Urvi D. Kothari

Hydrolysates from dilute acid pretreatment of biomass contain various biomass degradation products which are inhibitory to enzymes and toxic to microorganisms. One of the main inhibitory compounds is acetic acid which is released from the lignin-hemicellulose matrix in the biomass. Acetic acid at...
