Degradation of Trichloroethylene by Bacteria Isolated from Activated Sludge
Trichloroethylene (TCE) is one of the most serious chlorinated pollutants of some groundwater of many industrial countries so that a possibility of its microbial degradation is an aim of many research and engineer teams. Natural strain C. testosteroni RF2 and its derivative strain VM obtained by mutagenesis were tested for their capability to trichloroethylene (TCE) degradation. Both strains we...
متن کاملDifferential sensitivity of nitrifying bacteria to silver nanoparticles in activated sludge.
Nitrification is known as one of the most sensitive processes affected when activated sludge is exposed to antimicrobial silver nanoparticles (AgNPs). The impact of AgNPs and their released silver ions (Ag(+) ) on the abundance, activity, and diversity of different nitrifying bacteria in wastewater treatment plants (WWTPs), however, is poorly understood. The present study investigated the impac...
متن کاملBiodegradation of anionic surfactants by isolated bacteria from activated sludge
*Corresponding author, Email: [email protected] Tel: +9821 2264 1842; Fax: +9821 2266 6016 ABSTRACT: Sodium dodecyl sulphate, (SDS) is an anionic surfactant that widely used all over the world. They will eventually end-up and accumulate in household or industrial sewage. Due to their high foaming capabilities, which can cause numerous problems in sewage treatment facilities as well as direct t...
متن کاملCommunities of Ammonia-oxidizing Archaea and Bacteria in Enriched Nitrifying Activated Sludge
In this study, communities of ammonia-oxidizing archaea (AOA) and ammonia-oxidizing bacteria (AOB) in nitrifying activated sludge (NAS) prepared by enriching sludge from a municipal wastewater treatment plant in three continuous-flow reactors receiving an inorganic medium containing different ammonium concentrations of 2, 10, and 30 mM NH4-N (NAS2, NAS10, and NAS30, respectively) were investiga...
متن کاملEcophysiological interaction between nitrifying bacteria and heterotrophic bacteria in autotrophic nitrifying biofilms as determined by microautoradiography-fluorescence in situ hybridization.
Ecophysiological interactions between the community members (i.e., nitrifiers and heterotrophic bacteria) in a carbon-limited autotrophic nitrifying biofilm fed only NH(4)(+) as an energy source were investigated by using a full-cycle 16S rRNA approach followed by microautoradiography (MAR)-fluorescence in situ hybridization (FISH). Phylogenetic differentiation (identification) of heterotrophic...
