Title: Multiscale Alterations in Sugar Cane Bagasse and Straw Submitted to Alkaline Deacetylation

Abstract

Alkaline deacetylation has emerged as a promising chemistry for pretreatments performed prior to enzymatic saccharification of lignocellulosic biomass. This process avoids complex pressurized reactors and opens new opportunities for lignin covalorization. In this work, we evaluate the chemical and morphological response of sugar cane bagasse and straw submitted to alkaline treatments. Alkaline solutions for deacetylation (0.4% w/w NaOH, 70 degrees C, 3 h) as well as proximal conditions (0.1-0.7% NaOH, 55-85 degrees C, 1-5 h) chosen by 23 experimental design were evaluated. The deacetylation treatment removes ~90% of the acetyl groups and 20-30% of the lignin from both bagasse and straw, while removal of ~20% of the xylan and glucan is observed in straw, but not in bagasse. Considering nanoscale structural alterations, neither cellulose cocrystallization (evaluated by X-ray diffraction) nor formation of lignin aggregates (evaluated by thermoporometric signature) are observed after the alkaline conditions, in contrast to observations after hydrothermal treatments. Furthermore, calorimetric thermoporometry as well as scanning and transmission electron microscopies show substantial introduction of nanoscale porosity and loosening of the tissue and cell wall structures, indicating desirable mechanical weakening and gains in enzyme accessibility. These results provide fundamental and practical knowledge for biorefineries based on alkaline deacetylation ofmore » sugar cane bagasse and straw.« less

IMPROVED BIOREFINERY FOR THE PRODUCTION OF ETHANOL, CHEMICALS, ANIMAL FEED AND BIOMATERIALS FROM SUGAR CANE

Technical Report Day, Donal F

The Audubon Sugar Institute (ASI) of Louisiana State University’s Agricultural Center (LSU AgCenter) and MBI International (MBI) sought to develop technologies that will lead to the development of a sugar-cane biorefinery, capable of supplying fuel ethanol from bagasse. Technology development focused on the conversion of bagasse, cane-leaf matter (CLM) and molasses into high value-added products that included ethanol, specialty chemicals, biomaterials and animal feed; i.e. a sugar cane-based biorefinery. The key to lignocellulosic biomass utilization is an economically feasible method (pretreatment) for separating the cellulose and the hemicellulose from the physical protection provided by lignin.

Alkali-explosion pretreatment of straw and bagasse for enzymic hydrolysis

Journal Article Puri, V P ; Pearce, G R - Biotechnol. Bioeng.; (United States)

Sugarcane bagasse and wheat straw were subjected to alkali treatment at 200/sup 0/C for 5 minutes and at 3.45 MPa gas pressure (steam and nitrogen), followed by an explosive discharge through a defibrating nozzle, in an attempt to improve the rate and extent of digestibility. The treatment resulted in the solubilization of 40-45% of the components and in the production of a pulp that gave saccharification yields of 80 and 65% in 8 h for bagasse and wheat straw, respectively. By comparison, alkali steaming at 200/sup 0/C (1.72 MPa) for 5 minutes gave saccharification yields of only 58 and 52%more »« less

Saccharification and fermentation of sugar cane bagasse by Klebsiella oxytoca P2 containing chromosomally integrated genes encoding the Zymomonas mobilis ethanol pathway

Journal Article Doran, J B ; Aldrich, H C ; Ingram, L O - Biotechnology and Bioengineering; (United States)

Pretreatment of sugar cane bagasse is essential for a simultaneous saccharification and fermentation (SSF) process which uses recombinant Klebsiella oxytoca strain P2 and Genencor Spezyme CE. Strain P2 has been genetically engineered to express Zymomonas mobilis genes encoding the ethanol pathway and retains the native ability to transport and metabolize cellobiose (minimizing the need for extracellular cellobiase). In SSF studies with this organism, both the rate of ethanol production and ethanol yield were limited by saccharification at 10 and 20 filter paper units (FPU) g[sup [minus]1] acid-treated bagasse. Dilute slurries of biomass were converted to ethanol more efficiently (over 72%more »« less

Pretreated sugar cane bagasse as a model for cattle feeding

Conference Fontana, J D ; Ramos, L P ; Deschamps, F C

Pretreatment under mild conditions in the presence of water (solvolysis) or aqueous orthophosphoric acid (phosphorolysis) was used to increase the nutritional value of sugar cane bagasse for cattle feeding. The best pretreatment conditions were defined as those in which the highest in situ degradability rates (ruminal digestion) were achieved with the least energy consumption and/or production of inhibitory products. Heating sugar cane bagasse up to 197{degrees}C (13.5 atm) at a 4:1 (w/w) water ratio was shown to be a compromised condition for solvolysis, as higher temperatures would require more energy consumption without adding too much to the already high 60%more »« less
Effect of Protic Ionic Liquids in Sugar Cane Bagasse Pretreatment for Lignin Valorization and Ethanol Production

Journal Article Pin, Thaynara C. ; Rabelo, Sarita C. ; Pu, Yunqiao Joseph ; ... - ACS Sustainable Chemistry & Engineering

Ionic liquids have been called designer solvents because it is possible to fine-tune their properties from a huge range of possible combinations of cations and anions. In this work, we evaluate the potential of protic ionic liquids (PILs) in the fractionation of sugar cane bagasse in a biorefinery context. Here, the PILs were designed to selectively solubilize lignin and leave a polysaccharides solid fraction. The carbohydrate fraction was further hydrolyzed to obtain pentose and hexose sugars, which were fermented using a pentose-consuming yeast. The results have shown that, differently from pretreatments that solubilize hemicelluloses, pentoses could be fermented together withmore »« less
