Polyethylene (PE) waste disposal is a major issue now days that poses serious threats to human and environmental health. Among the methods of dealing with problem, photocatalytic degradation in visible light an alternative option has received attention recently. The photo catalyst, generally used, titania nanoparticle form. In current study, complexity employing larger surface area nanomaterial form nanotubes been investigated. Prepared nanostructures were characterized by SEM, EDS, XRD, BET...

Abstract Two Pseudomonas species (designated strains B1 and X1) were isolated from an aerobic pilot‐scale fluidized bed reactor treating groundwater containing benzene, toluene, p ‐xylene (BTX). Strain grew with benzene toluene as the sole sources of carbon energy, it cometabolized in presence toluene. X1 on ‐xylene, but not benzene. In single substrate experiments, appearance biomass lagged consumption growth substrates, suggesting that uptake may be growth‐rate limiting for these...
ABSTRACT Bioavailability of pesticides sorbed to soils is an important determinant their environmental fate and impact. Mineralization atrazine was studied in soil clay slurries, a desorption-biodegradation-mineralization (DBM) model developed quantitatively evaluate the bioavailability atrazine. Three atrazine-degrading bacteria that utilized as sole N source ( Pseudomonas sp. strain ADP, Agrobacterium radiobacter J14a, Ralstonia M91-3) were used assays. Assays involved establishing...

Dissolved organic matter (DOM) plays a major role in defining biological systems and it influences the fate transport of many pollutants. Despite importance DOM, understanding how environmental anthropogenic factors influence its composition characteristics is limited. This study focuses on DOM exported as stormwater from suburban urban sources. Runoff was collected before entering surface waters characterized using specific ultraviolet absorbance at 280 nm (a proxy for aromaticity),...
An experiment was performed in a carbon tetrachloride (CT)- and nitrate-contaminated aquifer at Schoolcraft, MI, to evaluate bioaugmentation with Pseudomonas stutzeri KC, denitrifying bacterium that degrades CT without producing chloroform (CF). A test section of the treated create pH conditions favorable for KC then inoculated culture grown aerobically on site. Activity sustained pulses acetate-amended groundwater, followed by "chase" acetate-free water. In regions effective substrate...
We give the analysis of computational complexity coalition structure generation over graphs. Given an undirected graph G = (N,E) and a valuation function v : P(N) → R subsets nodes, problem is to find partition N into connected subsets, that maximises sum components values. This generally NPcomplete; in particular, it hard for defined class functions which are independent disconnected membersthat is, two nodes have no effect on each others marginal con- tribution their vertex separator....

The added organism Pseudomonas stutzeri KC (strain KC), denitrifying bacterium that cometabolically degrades CT without producing chloroform (CF). To introduce maintain strain the aquifer, row closely spaced (1-m) injection/extraction wells were installed normal to direction groundwater flow near leading edge plume. resulting system used establish...
Abstract Batch and column techniques were utilized to determine retardation coefficients of two nonionic organic compounds: benzene dimethylphthalate. Three sandy soil materials with medium high C content used as sorbents. data consistently overestimated the compounds. Several previously reported factors that may cause discrepancy between experimentally investigated. Sorption nonsingularity, sorption nonequilibrium, presence immobile water regions in column, reduction particle spacing...
Limited bioavailability of organic pollutants in soil may be a detriment to the successful application bioremediation. The availability soil-sorbed biphenyl two biphenyl-degrading bacteria, Pseudomonas putida P106 and Rhodococcus erythropolis NY05, was assessed using kinetic mineralization assay. Biphenyl aged four soils different carbon (OC) contents (0.4−7.8%) for up 274 days. With biphenyl-soil contact time 24 h, initial rates (IMRs) ranged from 2.6 3.5 μg·L-1·min-1 strain 3.8 0.92 NY05....
The degradation of naphthalene was studied in soil−slurry systems, and a quantitative model developed to evaluate the bioavailability sorbed-phase contaminant.

Desorption of organic contaminants from soil can be modeled by dividing the desorption time−concentration profile into three distinct regimes. These are characterized that occurs faster than experimental sampling scheme, at a rate is captured it, and for which duration experiment data uncertainty obscures rate.
