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) ...
Antinociceptive and antiplasmodial activities of cassane furanoditerpenes from Caesalpinia volkensii H. root bark
(Elsevier, 2012-01-01)
The chloroform and ethyl acetate extract (100mg/kg) of Caesalpinia volkensii H. exhibited
significant (P≤ 0.05) antinociceptive activities using hot plate and writhing tests in mice
while the later showed antiplasmodial ...
Influence of region of production on relative clonal plain tea quality parameters in Kenya
(Elsevier, 2010-04-01)
Tea is grown in diverse regions with varying climates. Growers seek high-yielding and
superior quality cultivars to improve profitability of the enterprise. A superior quality genotype
in one location is assumed to ...
The influence of geographical area of production and nitrogenous fertiliser on yields and quality parameters of clonal tea
(2010-04-01)
Variations in requirements for tea production in Kenya and factors controlling
growth and production of secondary metabolites responsible for the quality parameters are
indicative of the need for non-uniform recommendations. ...
Spatial distribution and habitat characterization of mosquito species during the dry season along the Mara River and its tributaries, in Kenya and Tanzania
(Bio Med Central, 2018-12)
Vector-borne diseases are increasingly becoming a major health problem among
communities living along the major rivers of Africa. Although larger water bodies such as
lakes and dams have been extensively researched, ...
