Diosgenin quantification, characterisation and chemical composition in a tuber collection of Dioscorea spp. in the state of Jalisco, Mexico
16-05-2013 | María Lourdes Contreras‐Pacheco, Fernando Santacruz‐Ruvalcaba, Jorge A. García‐Fajardo, José Jesús Sánchez G., Mario ..., International Journal of Food Science & Technology, 2013
Summary Dioscorea spp. tubers are known commonly as camote de cerro to the state of Jalisco, México. Besides its use as food, it contains diosgenin, a raw material used widely for synthesising steroid hormones. The purpose of the present research was to determine diosgenin contents by gas ...
Effect of microwave‐assisted extraction on the release of polyphenols from ginger (Zingiber officinale)
15-05-2013 | Ismail Rahath Kubra, Devender Kumar, Lingamallu Jagan Mohan Rao, International Journal of Food Science & Technology, 2013
Summary The significance of different variables viz. temperature, time and solvent at constant power in microwave‐assisted extraction (MAE) process of ginger was studied and compared with conventional method. Aqueous ethanol (50%) provided higher yields of extract as well as the highest ...
Supercritical CO2 extraction of oleanolic acid from grape pomace
15-05-2013 | Laura Chronopoulou, Angelo C. Agatone, Cleofe Palocci, International Journal of Food Science & Technology, 2013
Summary In this work, we investigated the possibility to extract oleanolic acid through supercritical fluid extraction from waste materials such as grape pomace, which can represent a yet unexploited source of highly added‐value products. Preliminary supercritical fluid extractions were ...
Chemistry and combustion of fit-for-purpose biofuels
13-05-2013 | Author(s): David A Rothamer , Timothy J Donohue, Current Opinion in Chemical Biology, 2013
Publication date: Available online 8 May 2013 Source:Current Opinion in Chemical Biology Author(s): David A Rothamer , Timothy J Donohue From the inception of internal combustion engines, biologically derived fuels (biofuels) have played a role. Nicolaus Otto ran a predecessor to ...
Production of advanced biofuels in engineered E. coli
13-05-2013 | Author(s): Miao Wen , Brooks B Bond-Watts , Michelle CY Chang, Current Opinion in Chemical Biology, 2013
Publication date: Available online 6 May 2013 Source:Current Opinion in Chemical Biology Author(s): Miao Wen , Brooks B Bond-Watts , Michelle CY Chang Commercial fermentation processes have long taken advantage of the synthetic power of living systems to rapidly and efficiently ...
Π–Π Stacking Increases the Stability and Loading Capacity of Thermosensitive Polymeric Micelles for Chemotherapeutic Drugs
10-05-2013 | Yang Shi; Mies J. van Steenbergen; Erik A. Teunissen; Luı́s Novo; Sabine Gradmann; Marc Baldus; Cornelus F ..., Biomacromolecules, 2013
Thermosensitive amphiphilic block copolymers self-assemble into micelles above their lower critical solution temperature in water, however, the micelles generally display mediocre physical stability. To stabilize such micelles and increase their loading capacity for chemotherapeutic drugs, ...
A global view on world ethanol markets and trade flows
09-05-2013 | Claudiu Covrig, Biofuels, Bioproducts and Biorefining, 2013
Since the financial crisis and the subsequent global economic recession, the ethanol market has been impacted by increased volatility and change. Dr Claudiu Covrig provides a global view on the ebbs and flows in ethanol markets over the last few years. © 2013 Society of Chemical Industry ...
Marker‐free genetic engineering of the chloroplast in the green microalga Chlamydomonas reinhardtii
07-05-2013 | Hsu‐Ching Chen, Anastasios Melis, Plant Biotechnology Journal, 2013
Summary The work applied a transgene expression method based on the replacement of an inactive rbcL gene as the selection marker in Chlamydomonas reinhardtii chloroplasts. The native rbcL gene in strain CC2653 has a point mutation that causes early translation termination, thus resulting ...
Separation of Hemicellulose and Cellulose from Wood Pulp by Means of Ionic Liquid/Cosolvent Systems
07-05-2013 | Carmen Froschauer; Michael Hummel; Mikhail Iakovlev; Annariikka Roselli; Herwig Schottenberger; Herbert Sixta, Biomacromolecules, 2013
Pulp of high cellulose content, also known as dissolving pulp, is needed for many purposes, including the production of cellulosic fibers and films. Paper-grade pulp, which is rich in hemicellulose, could be a cheap source but must be refined. Hitherto, hemicellulose extraction procedures ...
Investigation of vinegar production using a novel shaken repeated batch culture system
06-05-2013 | Tino Schlepütz, Jochen Büchs, Biotechnology Progress, 2013
Abstract Nowadays, bioprocesses are developed or optimized on small sale. Also vinegar industry is motivated to reinvestigate the established repeated batch fermentation process. As yet, there is no small scale culture system for optimizing fermentation conditions for repeated batch ...
