Pretreatment is a highly expensive and energy-consuming step in lignocellulosic biomass processing. Therefore, it is vital to study and optimize different pretreatment methods to find a most efficient production process. The biomass was milled with the Szego Mill™ using three different approaches: dry milling, wet milling and for the first time nitrogen assisted wet milling was tested. Bioethanol and biogas production were studied, but also fibre analysis and SEM (scanning electron microscope) analysis were carried out to characterize the effect of different milling approaches. In addition, two different process flows were used to evaluate the efficiency of downstream processing steps. The results show that pretreatment 1 of barely straw with the Szego Mill™ enabled obtaining glucose concentrations of up to 7 g L− in the hydrolysis mixture, which yields at hydrolysis efficiency of 18%.

  • Effect of Alkaline Pretreatments on the Enzymatic Hydrolysis of Wheat Straw
    Effect of alkaline pretreatments on the enzymatic hydrolysis of wheat straw N. Kontogianni, E.M. Barampouti, S. Mai, D. Malamis, M. Loizidou* National Technical University of Athens, School of Chemical Engineering, Unit of Environmental Science & Technology, 9 Iroon Polytechniou Str., Zographou Campus, GR-15780 Athens, Greece Keywords: alkaline peroxide, alkaline pretreatments, CellicCTec2, enzymatic hydrolysis, wheat straw Introduction Lignocellulosic materials are mainly composed of cellulose, hemicellulose and lignin. Lignin is considered to be the major barrier to the enzymatic hydrolysis of cellulose towards the production of fermentable sugars. Therefore, removing lignin from the lignocellulosic raw materials is favorable to reducing the recalcitrance of lignocellulose for enzymatic attack. For this purpose, various pretreatment technologies have been developed to improve the removal of lignin from the compact structure of plant cell walls and enhance the digestibility of cellulose by enzymes. Wheat straw is an abundant agriculture residue worldwide. In this work, wheat straw was firstly alkaline pretreated under selected chemicals and then subsequently it was enzymatically hydrolysed. Materials and Methods Wheat straw (WS) was obtained from Aspropyrgos province, Greece. The wheat straw was milled (FRITSCH Cutting mill Pulverisette 15) to 1 mm. The milled straw mainly composed of 33.8% cellulose, 45.1% hemicellulose, 16.4% lignin (15.4% Klason lignin and 1.0% acid-soluble lignin), and 4.7% ash. All chemical reagents were of analytical grade and used without further purification. The commercial enzymatic formulation CelliCTec2 was kindly donated by Novozymes (Denmark). Total cellulase activity (FPU) was measured against filter paper by the standard IUPAC method and found to be 223 FPU/mL.

  • Purity Tests for Modified Starches. Residue Monograph Prepared By
    Residue Monograph prepared by the meeting of the Joint FAO/WHO Expert Committee on Food Additives (JECFA), 82nd meeting 2016 Purity Tests for Modified Starches This monograph was also published in: Compendium of Food Additive Specifications. Joint FAO/WHO Expert Committee on Food Additives (JECFA), 82nd meeting 2016. FAO JECFA Monographs 19 © FAO/WHO 2016 1 of 4 PURITY TESTS FOR MODIFIED STARCHES Carboxyl groups Principle The carboxyl containing starch is equilibrated with mineral acid to convert carboxyl salts to the acid form. Cations and excess acid are removed by washing with water. The washed sample is gelatinized in water and titrated with standard alkali. NOTE: Native phosphate groups present in potato starch increase the titre found in this method (See NOTE 6). Reagents Hydrochloric Acid Solution, 0.10 N: Standardization unnecessary Sodium Hydroxide Solution, 0.10 N : Standardized Phenolphthalein Indicator, 1% Procedure If necessary, grind sample completely through a laboratory cutting mill to 20 mesh or finer, taking precautions to prevent any significant change in moisture, and mix thoroughly. Weigh accurately a sample containing not more than 0.25 milliequivalents of carboxyl (Note 1), and transfer quantitatively to a 150-ml beaker. Add 25 ml of 0.1 N hydrochloric acid and stir occasionally over a period of 30 min. Vacuum filter the slurry through a medium porosity fritted-glass crucible or small funnel, using a fine stream of water from a wash bottle to aid quantitative transfer of the sample. Wash the sample with distilled water (300 ml usually sufficient) until the filtrate is free from chloride determined by silver nitrate test (NOTE 2).

  • Critical Factors in Determining Fiber in Feeds and Forages
    Critical Factors in Determining Fiber in Feeds and Forages AAFCO’s Laboratory Methods and Services Committee Fiber Best Practices Working Group January 2017 Introduction From the nutritional perspective, fiber is defined as the hydrolytically indigestible partially fermentable components of feed. Chemically, these components are a variable mixture of cellulose, hemicelluloses, lignin, and soluble dietary fibers (e.g., pectins). Nutritionists need a practical and routine means of measuring fiber and must compromise between the theoretical concept of fiber and the utility of using chemical solubility to isolate and measure fractions that closely resemble the nutritionally defined fraction called fiber. Because there is no guarantee of direct correspondence between chemical solubility and nutritional availability, in reality, fiber is defined by the method used to isolate it. The actual definition of fiber becomes method- dependent, which explains why there are so many different fiber analyses (crude fiber, acid detergent fiber, neutral detergent fiber, amylase-neutral detergent fiber, total dietary fiber, etc.). The abundance of fiber methods is complicated further by the modifications of each method that are commonly used. Sometimes these modifications are developed to meet the specific needs of a particular application or research project. Other times modifications are made for convenience or to increase the speed of fiber analysis. Because fiber is defined by the method used to isolate it, it should be clear that method modifications have the potential to result in a fiber value that is not comparable with the parent method and cannot be reported using the same test name. The sensitivity of fiber values to a method suggests that fiber methods must be followed exactly to be reproducible.

  • Moisture Is Removed from the Sample by Distillation As an Azeotrope with Benzene
    Feedstuffs Analysis G-14-1 MOISTURE (Azeotropic Distillation) PRINCIPLE Moisture is removed from the sample by distillation as an azeotrope with benzene. The water is collected in a suitable trap and its volume is measured at a known temperature. SCOPE This method is applicable to corn gluten feed, corn gluten meal and related feed products from corn (Note 1). SPECIAL APPARATUS Recommended equipment for azeotropic distillation is available from several sources (see sketch). 1. Distilling Flask: KIMAX or PYREX short neck, flat bottom boiling flask, 500 mL capacity, with standard-paper 24/40 neck (e.g., Cat. No. F4020- 500 or F4022-500, Baxter Scientific Products, 1430 Waukegan Rd., McGaw Park, Illinois 60085) 2. Moisture Trap: Bidwell & Sterling, PYREX, 5 mL capacity, with 0.1 mL graduations (Note 2), and with standard-taper 24/40 joints for connecting the distilling flask and reflux condenser (e.g., Cat. No. 7705, Ace Glass Incorporated, P.O. Box 688, 1430 Northwest Blvd., Vineland, New Jersey 08360) 3. Condenser: PYREX, West-type with drip tip and 40 cm jacket. The bottom end has a standard-taper 24/40 joint for attaching the moisture trap; the upper end extends 3 inches beyond the jacket to allow a test tube closure during distillation. 4. Hot Plate-Stirrer: The unit should provide a maximum temperature (plate surface) of 800 °F and a stirring range of 250 to 1000 rpm. Stepless individual control of both temperature and stirring rate is necessary. (e.g., Analytical Methods of the Member Companies of the Corn Refiners Association, Inc.

SPECIAL APPARATUS 1. Digestion Apparatus: A multi-unit assembly with rheostat controlled electric heater, and condensers to fit 600 mL beakers, designed specifically for crude fiber determinations, is recommended. Heaters must be adjustable to the temperature that will bring 200 mL of water at 25 °C to a rolling boil in 15 ± 2 minutes (Note 1). 2. Filtering Device: A California Modified Buchner Funnel, two-piece polyethylene, with a 200 mesh stainless steel screen, is recommended. 3. Muffle Furnace: Equipped with a pyrometer and capable of operating at temperatures up to 600 °C. 4. Drying Oven: Forced draft or convection air oven, operating at 130 ± 2 °C. REAGENTS 1. Sodium Hydroxide Solution, 0.312 N (1.25%): Prepare and standardize against potassium acid phthalate using phenophthalein indicator. 2.
