Abstract New transportation fuels are badly needed to reduce our heavy dependence on imported oil and the release of greenhouse gases that cause global climate change; cellulosic biomass is only inexpensive resource can be used for sustainable production large volumes liquid sector has historically favored. Furthermore, biological conversion take advantage power biotechnology huge strides toward making biofuels cost competitive. Ethanol particularly well suited marrying this combination...
Compared with batch systems, flowthrough and countercurrent reactors have important potential advantages for pretreating cellulosic biomass, including higher hemicellulose sugar yields, enhanced cellulose digestibility, reduced chemical additions. Unfortunately, they suffer from high water energy use. To better understand these trade-offs, comparative data are reported on xylan lignin removal enzymatic digestibility of corn stover pretreated in over a range flow rates between 160 degrees 220...
Biological conversion of cellulosic biomass to fuels and chemicals offers the high yields products vital economic success potential for very low costs. Enzymatic hydrolysis that converts lignocellulosic fermentable sugars may be most complex step in this process due substrate-related enzyme-related effects their interactions. Although enzymatic higher yields, selectivity, lower energy costs milder operating conditions than chemical processes, mechanism relationship between substrate...
Abstract Cellulase and bovine serum albumin (BSA) were added to Avicel cellulose solids containing 56% 28% lignin from dilute sulfuric acid pretreatment of corn stover. Little BSA was adsorbed on cellulose, while pretreated stover considerable amounts this protein. On the other hand, cellulase highly both substrates. Adding a 1% concentration prior enzyme addition at 15 FPU/g enhanced filter paper activity in solution by about factor 2 beta‐glucosidase 14. Overall, these results suggested...
Abstract Low‐cost renewable lignin has been used as a precursor to produce porous carbons. However, date, it not easy obtain high surface area carbon without activation processes or templating agents. Here, we demonstrate that low molecular weight yields highly with more graphitization through direct carbonization additional We found and oxygen consumption during are critical factors area, graphitized This from low‐cost sources is good candidate for supercapacitor electrode materials.
Lignin is the most abundant aromatic biopolymer in biosphere and it comprises up to 30% of plant biomass. Although lignin recalcitrant component cell wall, still there are microorganisms able decompose or degrade it. Fungi recognized as widely used microbes for degradation. However, bacteria have also been known be utilize a carbon energy source. Bacillus ligniniphilus L1 was selected this study due its capability alkaline single source excellent ability survive extreme environments.To...
Biological lignin valorization has emerged as a major solution for sustainable and cost-effective biorefineries. However, current biorefineries yield with inadequate fractionation bioconversion, yet substantial changes of these biorefinery designs to focus on could jeopardize carbohydrate efficiency increase capital costs. We resolve the dilemma by designing 'plug-in processes lignin' integration leading pretreatment technologies. Substantial improvement bioconversion synergistic enhancement...
Abstract Production of hydrocarbon fuel from biomass‐derived lignin sources with current vision biorefinery infrastructure would significantly improve the total carbon use in biomass and make conversion more economically viable. Thus, developing specialty commodity products derived‐lignin has been an important industrial scientific endeavor for several decades. However, deconstruction lignin's complex polymeric framework into low molecular weight reactive moieties amenable deoxygenation...
In this paper we study the carbon efficiency of combining hydrolysis and pyrolysis processes using maple wood as a feedstock. A two-step in batch reactors, that consisted thermochemical pretreatment water followed by enzymatic hydrolysis, achieved an 88.7 wt% yield glucose 85 xylose liquid streams. The residue obtained was 80 lignin. combination TGA pyroprobe studies used for pure wood, hemicellulose-extracted lignin from wood. Pyrolysis raw produced 67 condensable products (or bio-oils)...
Abstract The slow down in enzymatic hydrolysis of cellulose with conversion has often been attributed to declining reactivity the substrate as more easily reacted material is thought be consumed preferentially. To better understand cause this phenomenon, reaction nearly pure Avicel was interrupted over course complete hydrolysis. Then, solids were treated proteinase degrade cellulase enzymes remaining on solid surface, followed by inhibitors inactive and successive washing water, 1.0 M NaCl...
