Tenax extraction for exploring rate-limiting factors in methyl-β-cyclodextrin enhanced anaerobic biodegradation of PAHs under denitrifying conditions in a red paddy...
(Elsevier, 2014-01-15)
The effectiveness of anaerobic bioremediation systems for PAH-contaminated soil
may be constrained by low contaminants bioaccessibility due to limited aqueous solubility
and lack of suitable electron acceptors. Information ...
Response surface methodology to understand the anaerobic biodegradation of organochlorine pesticides (OCPs) in contaminated soil—significance of nitrate conce...
(2014-09-01)
Abstract Purpose Problems associated with Organochlorine pesticide (OCP)-contaminated
soils have received wide attention. To understand the anaerobic biodegradation process
constraints, innovative mathematical analysis ...
Isolation and characterization of a toxic metal-tolerant Phenanthrene-degrader Sphingobium sp. in a two-liquid-phase partitioning bioreactor (TPPB)
(2013-10-01)
A phenanthrene-degrading strain PHE3, identified as the genus of Sphingobium,
was isolated using a two-liquid-phase partitioning bioreactor. More than 96% of the initial
amount (up to 100 mg l− 1 silicone oil) of ...
Does powder and granular activated carbon perform equally in immobilizing chlorobenzenes in soil?
(Royal Society of Chemistry, 2015)
The objective of this study is to compare the efficacies of powder activated carbon (PAC) and
granular activated carbon (GAC) as amendments for the immobilization of volatile
compounds in soil. Soil artificially-spiked ...
Effects of pH and metal ions on oxytetracycline sorption to maize-straw-derived biochar
(Elsevier, 2013-05-30)
Biochars produced from biomass residues have been recognized as effective sorbents to
hydrophobic compounds, but knowledge on sorption of antibiotics to biochar and its
mechanisms are still inadequate. Sorption of ...
Enhanced degradation of 14 C-HCB in two tropical clay soils using multiple anaerobic–aerobic cycles
(2013-02-28)
The aim of the study was to induce and enhance the degradation of hexachlorobenzene
(HCB), a highly-chlorinated persistent organic pollutant, in two ecologically different tropical
soils: a paddy soil (PS) and a non-paddy ...
Immobilization of chlorobenzenes in soil using wheat straw biochar
(American Chemical Society, 2013-04-25)
Biochar has shown great potential for immobilizing organic contaminants in soil. In this
study, pentachlorobenzene (PeCB), 1, 2, 4, 5-tetrachlorobenzene (1, 2, 4, 5-TeCB), and 1, 2,
4-trichlorobenzene (1, 2, 4-TCB) ...
Changes in thearubigin fractions and theaflavin levels due to variations in processing conditions and their influence on black tea liquor brightness and total colour
(Elsevier, 2004-03-30)
Increase in coarser plucking standards significantly (P< 0.05) depressed levels of theaflavin
(TF; μmol/g), total colour and brightness (spectrophotometer) of black tea. But total
thearubigins (TR) TRSI, TRSII and ...
Flavanol composition and caffeine content of green leaf as quality potential indicators of Kenyan black teas
(1997)
The Ñavanol composition and ca† eine content of green tea leaf, black tea quality
parameters of theaÑavins, thearubigins, liquor brightness and total colour varied more
among clones than with time of the year. In green ...
Influence of region of production on clonal black tea chemical characteristics
(2008-05-01)
Production of black tea from the same vegetatively propagated (VP) cultivars, in Kenya and
Malawi, shows variations in both chemical composition and quality. Whereas it is possible to
produce black teas with similar ...
