    EFFECTS OF PRODUCT REMOVAL USING ION-EXCHANGE RESIN AND SODIUM HYDROXIDE PRETREATMENT IN MIXED-CULTURE FERMENTATION A Thesis by SHEN-CHUN HSU Submitted to the Office of Graduate and Professional Studies of Texas A&M University in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE Chair of Committee, Mark T. Holtzapple Committee Members, Ahmad K. Hilaly Zivko Nikolov Head of Department, M. Nazmul Karim May 2019 Major Subject: Chemical Engineering Copyright 2019 Shen-Chun Hsu ABSTRACT In mixed-culture fermentations of lignocellulosic biomass, periodical product removal has proven to reduce product inhibition and thereby increase biomass digestion. Previously, ion-exchange resin (Amberlite IRA-67) was employed in countercurrent fermentation, and different amounts of resin loadings (10–40 g wet resin per 1.38 L total liquid volume) were studied. Using the pre-established culture (office paper and oven-dried chicken manure), this research used higher resin loadings (50, 60, and 80 g wet resin per 1.34 L total liquid volume). The 0.3-L resin column was sustained by CO2 (gas flow rate: 1.5 L/min). Compared to 30 g resin loading, when higher loadings were introduced, biomass conversion dropped by 0.05–0.09 g NAVSdigested/g NAVSfeed. Furthermore, the yield plateaued at resin loadings greater than 40 g. Overall, the optimal resin loading for both biomass conversion and acid yield was 30–40 resin loading per 1.34 L total liquid volume, which corresponded to 21.74–29.20 g wet resin/Lliq. As indicators of digestibility, cellulase (Ctec3) and hemicellulose (Htec3) were used to saccharify pretreated corn stover.

    CHAPTER 19 CARBOXYLIC ACIDS O X arboxylic acids, compounds of the type RCOH, constitute one of the most fre- quently encountered classes of organic compounds. Countless natural products are Ccarboxylic acids or are derived from them. Some carboxylic acids, such as acetic acid, have been known for centuries. Others, such as the prostaglandins, which are pow- erful regulators of numerous biological processes, remained unknown until relatively recently. Still others, aspirin for example, are the products of chemical synthesis. The therapeutic effects of aspirin, welcomed long before the discovery of prostaglandins, are now understood to result from aspirin’s ability to inhibit the biosynthesis of prostaglandins. O O O (CH2)6CO2H COH CH3COH (CH2)4CH3 OCCH3 HO OH O Acetic acid PGE1 (a prostaglandin; a small amount Aspirin (present in of PGE1 lowers blood pressure vinegar) significantly) The chemistry of carboxylic acids is the central theme of this chapter. The impor- tance of carboxylic acids is magnified when we realize that they are the parent com- pounds of a large group of derivatives that includes acyl chlorides, acid anhydrides, esters, and amides. Those classes of compounds will be discussed in the chapter fol- 736 Back Forward Main Menu TOC Study Guide TOC Student OLC MHHE Website 19.1 Carboxylic Acid Nomenclature 737 lowing this one.

Richardson Candidate for the Degree Doctor of Philosophy ______________________________________ Dr. Neil Danielson, Director ______________________________________ Dr. Carole Dabney-Smith, Reader ______________________________________ Dr. Richard T. Taylor, Reader ______________________________________ Dr. Jiangjiang Zhu, Reader ______________________________________ Dr. Justin Saul, Graduate School Representative ABSTRACT HYDROPHILIC INTERACTION AND MICELLAR LIQUID CHROMATOGRAPHY APPROACHES FOR THE SEPARATION OF AROMATIC CARBOXYLIC ACID POSITIONAL ISOMERS PLUS ION EXCHANGE CHROMATOGRAPHY FOR THE SEPARATION OF SULFONATED COMPOUNDS by Ashley Elizabeth Richardson Separation of aromatic positional isomers is typically limited to separating a couple of the isomers in a class, not all of them. A novel HILIC method has been developed to separate ten aromatic carboxylic positional isomers, including the hydroxybenzoic acid isomers, hydroxycinnamic acid isomers, syringic, vanillic, ferulic, and sinapic acids, using a ternary mobile phase comprised of acetonitrile, ammonium acetate buffer, and pentane. This method is compatible with mass spectrometry (MS) detection and can separate the analytes in under 45 minutes with baseline resolution of all isomers. Terephthalic acid purity is extremely important during the production of polyethylene terephthalate. There are few methods available that can separate terephthalic acid from eight major impurities. Those impurities include two sets of positional isomers. Using micellar liquid chromatography (MLC), a method has been developed using an acidic sodium dodecyl sulfate (SDS) mobile phase, a C18 column, and a flow rate gradient to separate terephthalic acid from the eight impurities in less than 20 minutes with baseline resolution. Detection limits have been improved when compared to previous methods.
