Detection of benzene, toluene, ethyl benzene, and xylenes (BTEX) using toluene dioxygenase-peroxidase coupling reactions.
We have developed a simple, whole-cell bioassay for the detection of bioavailable benzene, toluene, ethyl benzene, and xylenes (BTEX) and similar compounds. A genetically engineered E. coli strain expressing toluene dioxygenase (TDO) and toluene dihydrodiol dehydrogenase (TodD) was constructed, enabling the conversion of BTEX into their respective catechols, which were quickly converted into co...
متن کاملIntegrated Gas Sensing System of SWCNT and Cellulose Polymer Concentrator for Benzene, Toluene, and Xylenes
An integrated cellulose polymer concentrator/single-walled carbon nanotube (SWCNT) sensing system is demonstrated to detect benzene, toluene, and xylenes (BTX) vapors. The sensing system consists of functionalized cellulose as a selective concentrator disposed directly on top of a conductive SWCNT sensing layer. Functionalized cellulose concentrator (top layer) selectively adsorbs the target an...
متن کاملH2 drives metabolic rearrangements in gas-fermenting Clostridium autoethanogenum
Background The global demand for affordable carbon has never been stronger, and there is an imperative in many industrial processes to use waste streams to make products. Gas-fermenting acetogens offer a potential solution and several commercial gas fermentation plants are currently under construction. As energy limits acetogen metabolism, supply of H2 should diminish substrate loss to CO2 and ...
متن کاملShort-term adaptation during propagation improves the performance of xylose-fermenting Saccharomyces cerevisiae in simultaneous saccharification and co-fermentation
BACKGROUND Inhibitors that are generated during thermochemical pretreatment and hydrolysis impair the performance of microorganisms during fermentation of lignocellulosic hydrolysates. In omitting costly detoxification steps, the fermentation process relies extensively on the performance of the fermenting microorganism. One attractive option of improving its performance and tolerance to microbi...
متن کاملتغییرات روزانه غلظت ترکیبات (Benzene Toluene, Ethylbenzene Xylenes, BTEX) در هوای شهر تهران
سابقه و هدف: بنزن، تولوئن، اتیل بنزن و زایلن ها (BTEX) جزو ترکیبات آلی فرار بوده و انتشار آنها به محیط از طریق وسایل نقلیه موتوری و ترکیبات نفتی می باشد و اثرات مضر بر سلامتی دارد. پایش غلظت این ترکیبات و کنترل آنها برای پیشگیری از عوارض ناشی از آنها امری ضروری است. لذا این مطالعه به منظور بررسی تغییرات روزانه غلظت ترکیبات BTEX در هوای شهر تهران انجام شد. مواد و روشها: در این مطالعه مقطعی غلظت ...
