Bioavailability assessment of hexachlorobenzene in soil as affected by wheat straw biochar
(Elsevier, 2012-05-30)
Biochar incorporation with soil could increase sorption of organic contaminants, thereby reducing their bioavailability. In this study, the effects of wheat straw biochar on the sorption, dissipation and bioavailability ...
Extracellular polymeric substances enhanced mass transfer of polycyclic aromatic hydrocarbons in the two-liquid-phase system for biodegradation
(Springer-Verlag, 2011-05-01)
The objective was to elucidate the role of extracellular polymeric substances (EPS) in biodegradation of polycyclic aromatic hydrocarbons in two-liquid-phase system (TLPs). Therefore, biodegradation of phenanthrene (PHE) ...
Improved biodegradation of 1, 2, 4-trichlorobenzene by adapted microorganisms in agricultural soil and in soil suspension cultures
(Elsevier, 2011-08-01)
Inoculating soil with an adapted microbial community is a more effective bioaugmentation approach than inoculation with pure strains in bioremediation. However, information on the potential of different inocula from sites ...
Improved biodegradation of 1,2,4-trichlorobenzene by adapted microorganisms in agricultural soil and in soil suspension cultures
(Pedosphere, 2011)
Inoculating soil with an adapted microbial community is a more effective bioaugmentation approach than inoculation with pure strains in bioremediation. However, information on the potential of different inocula from sites ...
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 ...
Yield and Yield Stability of Four Population Types of Grain Sorghum in a Semi‐Arid Area of Kenya
(Crop Breeding, Genetics & Cytology, 2000-03-01)
Sorghum [Sorghum bicolor (L.) Moench] is widely grown in semi‐arid tropics where local farmers depend on the adaptability of their rainfed crops to unpredictable drought and other stress factors. To investigate the effects ...
TOLERANCE LEVEL OF ALTERNARIA SESAMI AND THE EFFECT OF SEED INFECTION ON YIELD OF SESAME IN KENYA
(Cambridge University Press, 2007-07)
Field plots of sesame (Sesamum indicum) with six different levels of seed infection with Alternaria sesami were monitored for Alternaria leaf spot severity at Kibwezi, eastern Kenya. The aim of the study was to determine ...
Yield improvement of Kenyan sesame varieties
(University of Nairobi, 2001)
In an effort to improve the yield of Kenyan sesame cultivars the seeds of three cultivars, SPS SIK6, SIK 096 and SPS SIK 50/1 were subjected to 300Gy, 400Gy and 600Gy of gamma rays. A first batch of seeds were subjected ...
