Electro-extractive fermentation for efficient biohydrogen production [PDF]
, 2011 Electrodialysis, an electrochemical membrane technique, was found to prolong and enhance the production of biohydrogen and purified organic acids via the anaerobic fermentation of glucose by Escherichia coli. Through the design of a model electrodialysis

HPLC Analysis of Secreted Organic Acids
Bio-Protocol, 2016 Under certain growth conditions some microorganisms secrete organic acids into the extracellular medium to relieve the accumulation of excess energy carriers, and/or to reduce toxic concentrations of organic acids. For example, a glycogen-deficient ∆glgC

Determination of organic acids evolution during apple cider fermentation using an improved HPLC analysis method [PDF]
, 2008 An efficient method for analyzing ten organic acids in food, namely citric, pyruvic, malic, lactic, succinic, formic, acetic, adipic, propionic and butyric acids, using HPLC was developed. Boric acid was added into the mobile phase to separate lactic and

Corrosion protection of AA2024 sealed anodic layers using the hydrophobic properties of carboxylic acids [PDF]
, 2009 The present study investigates the use of carboxylic acids as a post-treatment for sealed AA2024 anodised in tartaric–sulphuric acid electrolyte. Four monocarboxylic acids with different carbon chain lengths were tested ((CH3–(CH2)n–COOH with n=4, 8, 12 ...

New organic matter degradation proxies: Valid in lake systems? [PDF]
, 2004 We determined concentrations and diagenetic state of organic matter in two cores from Lake Zug, Switzerland. To obtain a general picture of organic matter decay in the lake, we measured bulk parameters such as total organic carbon, total nitrogen, and ...
