We report the draft genome sequence of Pseudomonas moraviensis R28-S, isolated from the municipal wastewater treatment plant of Moscow, ID. The strain carries a native mercury resistance plasmid, poorly maintains introduced IncP-1 antibiotic resistance plasmids, and has been useful for studying the evolution of plasmid host range and stability.

results the results showed that the fog amount in input raw sewage in the mwwtp from june 2011 to september 2011 was around 25.5 mg/l and the amount in treated wastewater was about 8.1 mg/l. the fog removal efficiency in this refinery was about 70% and met the environmental standards for the discharge (less than 10 mg/l) (p < 0.05). conclusions the effluent can be discharged to surface waters o...

eclaimed municipal wastewater is becoming a source of public water supplies in places where water is limited. In countries such as Japan, South Africa, and France, legislation encouraging innovative technologies that render wastewater fit for reuse has stimulated the development of alternative processes.1 The use of membranes in tertiary treatment and advanced purification evolved as a promisin...

The species Escherichia coli comprises different subgroups with distinct phylogeny, physiology and ecology and, thus, presumably, with different roles in antimicrobial resistance dissemination. E. coli strains isolated from raw and treated municipal wastewater and from urban water streams were characterized in terms of phylogenetic groups, antimicrobial resistance patterns and the presence of c...

Many fish use steroid hormones as pheromones to initiate behavioral and physiological changes during spawning. To assess the occurrence of steroid hormones with pheromonal properties in the aquatic environment and to evaluate the possibility that municipal wastewater discharges contain compounds that could affect fish reproduction by interfering with pheromones, several estrogens, androgens, an...

Aromatic compounds belong to one of most widely distributed classes of organic substances used in industry, services and households and, therefore they are relatively often measured in municipal wastewater. Their efficient biological degradation is essential to reduce the subsequent disposal of such substances into the waters of the receiver, or release into the atmosphere. The mineralization o...

A method combining ultrasound-assisted emulsification-microextraction (USAEME) with gas chromatography-mass spectrometry (GC-MS) was developed for simultaneous determination of four acidic pharmaceuticals, ibuprofen, naproxen, ketoprofen, and diclofenac, as well as four phenols, 4-octylphenol, 4-n-nonylphenol, bisphenol A, and triclosan in municipal wastewaters. Conditions of extraction and sim...

Low-energy cost wastewater treatment is required to change its current energy-intensive status. Although promising, the direct anaerobic digestion of municipal wastewater treatment faces challenges such as low organic content and low temperature, which require further development. The hydrolysis-aerobic system investigated in this study utilized the two well-proven processes of hydrolysis and a...

sludge production is an avoidable problem arising from the treatment of wastewater. the sludge remained after municipal wastewater treatment contains considerable amounts of various contaminants and if is not properly handled and disposed, it may produce extensive health hazards. on the other hand, this sludge has benefits for plants and soils. thereupon, land application of sludge has received...

Ozone and hydroxyl radical (*OH) reaction kinetics were measured for 14 antibacterial compounds from nine structural families, to determine whether municipal wastewater ozonation is likely to result in selective oxidation of these compounds' biochemically essential moieties. Each substrate is oxidized by ozone with an apparent second-order rate constant, k''(O3,app) > 1 x 10(3) M(-1) s(-1), at ...
