Dry biorefining maximizes the potentials of simultaneous saccharification and co‐fermentation for cellulosic ethanol production

02-Sep-2017 | Gang Liu, Qiang Zhang, Hongxing Li, Abdul Sattar Qureshi, Jian Zhang, Xiaoming Bao, Jie Bao, Biotechnology and Bioengineering, 2017

ABSTRACT Despite the well‐recognized merits of simultaneous saccharification and co‐fermentation (SSCF) on relieving sugar product inhibition on cellulase activity, a practical concomitance difficulty of xylose with inhibitors in the pretreated lignocellulose feedstock prohibits the essential ...

Large‐scale commercial production of cellulosic ethanol from agricultural residues: A case study of wheat straw in the Canadian Prairies

29-Aug-2017 | Edmund Mupondwa, Xue Li, Lope Tabil, Biofuels, Bioproducts and Biorefining, 2017

Abstract This paper provides a business case for a large‐scale wheat‐straw‐based cellulosic ethanol plant in the Canadian Prairies. Feedstock availability and costs were quantified for 11 locations representing the region’s agroecological soil zones. The economic feasibility of the cellulosic ...

Ethanol production from dilute‐acid steam exploded lignocellulosic feedstocks using an isolated multistress‐tolerant Pichia kudriavzevii strain

05-May-2017 | Shuo‐Fu Yuan, Gia‐Luen Guo, Wen‐Song Hwang, Microbial Biotechnology, 2017

Summary Renewable and low‐cost lignocellulosic wastes have attractive applications in bioethanol production. The yeast Saccharomyces cerevisiae is the most widely used ethanol‐producing microbe; however, its fermentation temperature (30–35°C) is not optimum (40–50°C) for enzymatic hydrolysis ...

Estimating the required logistical resources to support the development of a sustainable corn stover bioeconomy in the USA

23-Nov-2016 | Mahmood Ebadian, Shahab Sokhansanj, Erin Webb, Biofuels, Bioproducts and Biorefining, 2016

Abstract In this study, the logistical resources required to develop a bioeconomy based on corn stover in the USA are quantified, including field equipment, storage sites, transportation and handling equipment, workforce, corn growers, and corn lands. These resources are essential to mobilize ...

Enzymatic deconstruction of plant biomass by fungal enzymes

16-Oct-2016 | Author(s): Christian P Kubicek, Eva M Kubicek, Current Opinion in Chemical Biology, 2016

Publication date: December 2016 Source:Current Opinion in Chemical Biology, Volume 35 Author(s): Christian P Kubicek, Eva M Kubicek Lignocellulosic plant biomass is the world's most abundant carbon source and has consequently attracted attention as a renewable resource for production of ...

Enhanced cellulase recovery without β‐glucosidase supplementation for cellulosic ethanol production using an engineered strain and surfactant

03-Oct-2016 | Renliang Huang, Hong Guo, Rongxin Su, Wei Qi, Zhimin He, Biotechnology and Bioengineering, 2016

ABSTRACT Recycling cellulases by substrate adsorption is a promising strategy for reducing the enzyme cost of cellulosic ethanol production. However, β‐glucosidase has no carbohydrate‐binding module (CBM). Thus, additional enzymes are required in each cycle to achieve a high ethanol yield. In ...

A review of sugarcane bagasse for second‐generation bioethanol and biopower production

20-Jul-2016 | Tais Lacerda Bezerra, Art J. Ragauskas, Biofuels, Bioproducts and Biorefining, 2016

Abstract Sugarcane bagasse is a large‐volume agriculture residue that is generated on a ~540 million metric tons per year basis globally1,2 with the top‐three producing countries in Latin America being Brazil (~181 million metric ton yr−1),3 Mexico (ܾ15 million metric ton yr−1),4 and Colombia ...

Cloning, Expression and Characterization of Xylose Isomerase from the Marine Bacterium Fulvimarina pelagi in Escherichia coli

03-Jun-2016 | Curtis A. Lajoie, Joshua B. Kitner, Stephen J. Potochnik, Jakob M. Townsend, Christopher C. Beatty, Christine J. Kelly, Biotechnology Progress, 2016

Abstract Production of a xylose isomerase (XI) with high tolerance to the inhibitors xylitol and calcium, and high activity at the low pH and temperature conditions characteristic of yeast fermentations, is desirable for a simultaneous isomerization/fermentation process for cellulosic ethanol ...

Optimization of an acetate reduction pathway for producing cellulosic ethanol by engineered yeast

31-May-2016 | Guo‐Chang Zhang, In Iok Kong, Na Wei, Dairong Peng, Timothy L Turner, Bong Hyun Sung, Jung‐Hoon Sohn, Yong‐Su Jin, Biotechnology and Bioengineering, 2016

Abstract Xylose fermentation by engineered Saccharomyces cerevisiae expressing NADPH‐linked xylose reductase (XR) and NAD+‐linked xylitol dehydrogenase (XDH) suffers from redox imbalance due to cofactor difference between XR and XDH, especially under anaerobic conditions. We have demonstrated ...

Pilot‐scale cellulosic ethanol production using eucalyptus biomass pre‐treated by dilute acid and steam explosion

29-Apr-2016 | Shane McIntosh, Zhanying Zhang, Janice Palmer, Heng‐Ho Wong, William O.S. Doherty, Tony Vancov, Biofuels, Bioproducts and Biorefining, 2016

Abstract The widespread deployment of commercial‐scale cellulosic ethanol currently hinges on developing and evaluating scalable processes whilst broadening feedstock options. This study investigates whole Eucalyptus grandis trees as a potential feedstock and demonstrates dilute acid ...
