Simultaneous determination of NSO-heterocycles, homocycles and their metabolites in groundwater of tar oil contaminated sites using LC with diode array UV and fluorescence detection

Nitrate-dependent biodegradation of quinoline, isoquinoline, and 2-methylquinoline by acclimated activated sludge

“…One of the three quinolines was spiked and sodium nitrate was supplemented at desired COD/NO 3 -N ratio. The COD for quinoline, isoquinoline and 2-methylquinoline was theoretically estimated based on the following reactions: 3 (1)…”

“…Quinolinic compounds, including quinoline, isoquinoline, and methylquinoline, occur in many products such as coal tar, oil, creosote, pharmaceuticals, pesticides and dyes [1][2][3]. As many of these compounds are considered toxic, carcinogenic and mutagenic [4,5], it is essential to understand their biodegradability to assess their fate in the environment and in the wastewater treatment plants (WWTP).…”

Microbial transformation of benzothiophenes, with carbazole as the auxiliary substrate, by Sphingomonas sp. strain XLDN2-5

“…This liquid is a complex mixture that consists of polycyclic aromatic hydrocarbons, phenolic compounds and heterocyclic compounds (Gundlach et al, 1983;Mueller et al, 1989;Annweiler et al, 2001;Mundt & Hollender, 2005;Xu et al, 2006;Andersson et al, 2006). S-, N-and O-heterocyclic aromatic compounds constitute approximately 5-13 % of creosote (Mueller et al, 1989).…”

Decolorization of Turquoise Blue HFG byCoprinus plicatilisfor Water Bioremediation

“…A few studies have indicated that major metabolites were obtained from dye removal by white rot fungi (Mundt and Hollender 2005;Roland, Duisken, and J€ ahnigen 2008). A study of Dawkar et al (2008) showed that GC-MS analysis of disperse Brown 3REL dye samples revealed two major intermediate peaks, (4-ethoxyphenyl) amine-and 3-ethylaminomethylbenzene sulfonic acidlike substances, which is in good agreement with several other reports (Dawkar et al 2008).…”
