Effects of autoclaving and mercuric chloride sterilization on PAHs dissipation in a two-liquid-phase soil slurry
(Elsevier, 2011-02-01)
A two-liquid-phase (TLP) soil slurry system was employed to quantify the efficiencies of autoclaving and mercuric chloride sterilization in the dissipation of polycyclic aromatic hydrocarbons (PAHs). The fates of 11 PAHs ...
Enhanced microbial degradation of humin-bound phenanthrene in a two-liquid-phase system
(Elsevier, 2011-02-28)
Humin, the main component of soil organic matter, greatly influences the nonlinear sorption and desorption hysteresis of polycyclic aromatic hydrocarbons (PAHs) in soil. However, little is known about the bioavailability ...
Chemical extraction to assess the bioavailability of chlorobenzenes in soil with different aging periods
(Springer-Verlag, 2011-12-01)
Bioavailability is mainly influenced by aging and desorption of contaminants in soil. The purpose of this study was to investigate the desorption kinetics of chlorobenzenes (CBs) in soil and to investigate whether chemical ...
Isolation and Identification by Morphological and Biochemical Methods of Antibiotic Producing Microorganisms from the gut of Macrotermes michaelseni in Maseno, Kenya
(Journal of Applied Biology & Biotechnology, 2016-01)
The major gut microflora colonizing the hind gut of higher termites, include morphologically diverse
microorganisms. The objective of this study was to identify by morphological and biochemical methods of the
antibiotic ...
Pathogenic Vibrio strains isolated from human stool and water samples from Western Kenya
(Journal of Microbiology and Infectious Diseases, 2016)
Investigate the type of pathogenic Vibrio strains from water and stool samples collected from Migori, SonduMiriu, Nyando and Yala regions in Western Kenya.
extracts against Xanthomonas campestris Pv vesicatoria isolated from diseased African nightshade (Solanum scabrum)
(2018-09-30)
Solanum scabrum Mill is widely cultivated for consumption as a leafy vegetable, for medicinal purposes and as a source of income. Its productivity is faced with many challenges as farmers in Kenya have been recording low ...
Introducing a novel natural logarithmic indices and their corresponding percentages table towards quantitative estimation of plant tolerance levels to stressors
(2018)
The methods of evaluating tolerance levels of plants to stressors for many years have been based on indices and visual based scores which are more of descriptive and qualitative. Despite their ease of use the strategies ...
Soil properties along a gradient from hillslopes to the savanna plains in the Lambwe Valley, Kenya
(Elsevier, 2015-12-01)
Changes in land use and management strongly affect the physical and chemical properties of soils and their ecological functions. Especially, regions in East Africa have experienced dramatic land use changes in the past, ...
Patterns of CO2 exchange and productivity of the herbaceous vegetation and trees in a humid savanna in western Kenya
(Springer Netherlands, 2015-10-01)
Factors governing the dynamics between woody and herbaceous vegetation in the savanna are of ecological interest since they determine ecosystem productivity and stability. Field measurements were conducted in a humid savanna ...
Spatial heterogeneity in ecosystem structure and productivity in a moist Kenyan savanna
(Springer Netherlands, 2011-05-01)
Topographic variations and disturbances are key sources of spatial heterogeneity in the ecosystem and may influence its functioning, productivity, and carbon (C) storage. In water controlled ecosystems, structural and ...
