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 کاملComparative Energy and Exergy Analysis for the Utilization of Alternative Fuels in the Cement Kiln
The cement industry is one of the most energy and carbon-intensive industries. The energy and carbon reduction is an important issue in this industry. The present work considers the use of alternative fuels in the cement kilns. The amounts of excess air, the location of fuel and air entrance, as well as the amount of produced gas stacks, are the main design and operational variables in the kiln...
متن کاملDegradation of benzene, toluene, ethylbenzene, and xylenes (BTEX) by the lignin-degrading basidiomycete Phanerochaete chrysosporium.
Degradation of the BTEX (benzene, toluene, ethylbenzene, and o-, m-, and p-xylenes) group of organopollutants by the white-rot fungus Phanerochaete chrysosporium was studied. Our results show that the organism efficiently degrades all the BTEX components when these compounds are added either individually or as a composite mixture. Degradation was favored under nonligninolytic culture conditions...
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 ...
متن کاملBiological monitoring of petrochemical industry workers exposed to benzene, toluene, xylenes, methyl ethyl ketone, and phenol in Southern Iran
Background: Volatile organic compounds (VOCs), including carcinogens and toxic compounds, are produced in petrochemical industries. We undertook this study in order to study workers’ respiratory exposure to different VOC concentrations and compare the results with the urinary levels of its metabolites and study the correlation between them in petrochemical industries. Materials and Met...
