Application of Dynamic Temperature-Humidity Chamber for Measuring Moisture Sorption Isotherms of Biomaterials as Compared to the Conventional Isopiestic Method

open access: yesAdsorption Science & Technology, 2021
Measurement of water activity and moisture sorption isotherms of foods and biomaterials are important to determine the state of water. In this work, a dynamic temperature-humidity (DTH) controlled chamber was used to measure water sorption isotherm and ...

Sustainable production with obtaining glucosamine from crab exoskeletons

open access: yesCiência Rural
: Two chemical treatments, five enzymatic (pectinase, lipase, hemicellulase, hemicellulose-cellulase or lipase-pectinase) and one microbiological (Bacillus subtilis) treatment were evaluated to obtain glucosamine hydrochloride (Gluc-HCl) from the chitin

Enzymatic Hydrolysis of Oleuropein from Olea europea (Olive) Leaf Extract and Antioxidant Activities

open access: yesMolecules, 2015
Oleuropein (OE), the main polyphenol in olive leaf extract, is likely to decompose into hydroxytyrosol (HT) and elenolic acid under the action of light, acid, base, high temperature.

Shotgun Approach to Increasing Enzymatic Saccharification Yields of Ammonia Fiber Expansion Pretreated Cellulosic Biomass

open access: yesFrontiers in Energy Research, 2017
Most cellulolytic enzyme blends, either procured from a commercial vendor or isolated from a single cellulolytic microbial secretome, do not efficiently hydrolyze ammonia-pretreated (e.g., ammonia fiber expansion, AFEX) lignocellulosic agricultural crop ...

High throughput screening of hydrolytic enzymes from termites using a natural substrate derived from sugarcane bagasse

open access: yesBiotechnology for Biofuels, 2011
Background The description of new hydrolytic enzymes is an important step in the development of techniques which use lignocellulosic materials as a starting point for fuel production. Sugarcane bagasse, which is subjected to pre-treatment, hydrolysis and

Botrytis cinerea Transcription Factor BcXyr1 Regulates (Hemi-)Cellulase Production and Fungal Virulence

open access: yesmSystems, 2022
Botrytis cinerea is an agriculturally notorious plant-pathogenic fungus with a broad host range. During plant colonization, B. cinerea secretes a wide range of plant-cell-wall-degrading enzymes (PCWDEs) that help in macerating the plant tissue, but their

Studies on the Hemicellulases Part I

open access: yesNippon Nōgeikagaku Kaishi, 1970
(1) Asp. niger van Tieghemの麩麹培養抽出液のヘミセルラーゼをSE-Sephadex, DEAE-SephadexおよびSephadex G-100またはG-75のカラムクロマトグラフィーにより精製した結果, 4種のヘミセルラーゼ区分(H-I, H-II, H-III, H-IV)とキシロビオースに作用する1区分(キシロシダーゼ)とを得た. (2) これらのうち, H-I, H-IIおよびH-IIIは超遠心分析ならびに電気泳動分析の結果,単一物質にまで精製されたことが明らかになった.これら3種の酵素はいずれも“いなわら”および大豆種皮のアラビノキシランに作用するが,大豆種皮のガラクトマンナンに作用しないことからキシラナーゼに属するものとみなされる ...

Sustainable Palm Oil Extraction and Trends in the Use of Green Technologies: State‐of‐the‐Art and Future Directions

open access: yesJournal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Palm oil, which is extracted from the mesocarp of the fruit of the Elaeis guineensis Jacq. palm tree, is the most widely produced vegetable oil in the world. The extraction of this substance typically utilizes the conventional pressing method, a technique that is advantageous due to its low operating cost and simplified process.

The first description of an archaeal hemicellulase: the xylanase from Thermococcus zilligii strain AN1 [PDF]

open access: yes, 1999
A xylanase has been found in the archaeon Thermococcus zilligii strain AN1 (DSM 2770), which grows optimally at 75°C. The enzyme had a molecular mass of 95 kDa and a unique N-terminal sequence.

Production of bioethanol from residual barley and utilization of fermentation co‐products in animal nutrition

open access: yesEnvironmental Progress &Sustainable Energy, EarlyView.
Abstract The search for sustainable alternatives for bioethanol production has encouraged the valorization of agro‐industrial residues. This study evaluated the use of residual barley as a feedstock for bioethanol production and as a potential ingredient for ruminant feed.
