Mycobacterium sp. strain AP1 grew with pyrene as a sole source of carbon and energy. The identification of metabolites accumulating during growth suggests that this strain initiates its attack on pyrene by either monooxygenation or dioxygenation at its C-4, C-5 positions to give trans- or cis-4,5-dihydroxy-4,5-dihydropyrene, respectively. Dehydrogenation of the latter, ortho cleavage of the res...

Polycyclic aromatic hydrocarbons (PAHs) consist of a group over 100 different organic compounds mainly generated by anthropogenic activities. Because their low water solubility, they tend to be accumulated in sediment, where degradation rate is very low. Few studies have been carried out so far investigate the effects PAHs on Artemia franciscana. easy manage at laboratory scale, but it not sens...

We describe the first realization of liquid chromatographic separation in a droplet-based microfluidic system and develop a novel mode for microchip-based chromatography named as droplet-array liquid-liquid chromatography. In this system, two arrays of picoliter-scale droplets immobilized on both sidewalls of a microchannel with droplet trapping technique served as the stationary phase in chrom...

The photochemical reactions of organic compounds at the water surface lead to formation gas-phase molecules that may contribute new particle in atmosphere. Here, we observe sulfur (OS) are known secondary aerosol (SOA) precursors, upon irradiation aqueous solutions containing typical polycyclic aromatic hydrocarbons (PAHs) such as pyrene, fluoranthene, and phenanthrene well dimethylsulfoxide (D...

Two-liquid phase systems consisting of two insoluble liquids can be effective in removing high concentrations hydrocarbons from aqueous environments. In this study, the removal efficiencies Naphthalene (Nap), Acenaphthene (Acn), Fluorene (Flu), Fluoranthene (Flr), Anthracene (Ant), and Pyrene (Pyr) at two-liquid system were investigated. constituted using Bis (2-Ethylhexyl) sebacate (BES) ferme...
