A tod-luxCDABE fusion was constructed and introduced into the chromosome of Pseudomonas putida F1, yielding the strain TVA8. This strain was used to examine the induction of the tod operon when exposed to benzene, toluene, ethylbenzene, and xylene (BTEX) compounds and aqueous solutions of JP-4 jet fuel constituents. Since this system contained the complete lux cassette (luxCDABE), bacterial bio...

Urban air quality, and its variability in space and time, is a critical issue for human exposure and health related studies. In this work, we investigated the intra-urban distribution of SO2, NOx, NO2, Benzene, Toluene, and Xylenes in ambient air in one of the world’s most polluted cities, Lanzhou, China. Measurements were contemporarily carried out at forty locations in four seasonal campaigns...

The crystal structures of the Werner clathrates Ni(NCS)2(isoquinoline)4 (H) with para-xylene (px), meta-xylene (mx) and ortho-xylene (ox) have been elucidated. The kinetics of thermal decomposition of the three inclusion compounds were performed using the isothermal technique of Flynn and Wall. Selectivity of H for the xylene isomers was determined for both the liquid and vapour phase binary mi...

Automobile gasoline samples, 214 in total, were collected in 14 major cities in various parts of Japan in the autumn of 1983, and analyzed for aromatic and other contents on a Silicone OV 101 capillary GC column. n-Hexane, benzene, toluene and xylenes (3 isomers plus ethylbenzene) contents were 5.7, 1.4, 8.1 and 10.4% (v/v) as grand means, respectively. There was no remarkable vairation in cont...

Abstract The valorization of biomass-derived molecules into commodity chemicals is important for the transition to renewable feedstocks. model platform molecule 2,5-dimethylfuran (2,5-dmf) can be converted value-added aromatics such as benzene, toluene, and xylenes (BTX) over zeolite catalysts. To explore role acid site(s) in BTX selectivity, gallium has been isomorphously substituted framework...
