Degradation capacity of a 1, 2, 4-trichlorobenzene mineralizing microbial community for traces of organochlorine pesticides
(Elsevier, 2010-07-15)
A soil-borne microbial community isolated from a contaminated site was previously shown to mineralize
1,2,4-trichlorobenzene (1,2,4-TCB) under aerobic conditions. The key degrader in this community was
identified as ...
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 ...
Effect of anthropogenic activities on physico-chemical parameters and benthic macroinvertebrates of Mara river tributaries, Kenya
(2014)
The impact of anthropogenic activities within Bomet and Mulot towns on
water quality of Amala and Nyangores tributaries of Mara River, Kenya
was assessed using a combination of solid waste, physico-chemical
parameters ...
Influence of Water Availability on Food Crop Production in Semi-Arid Areas in Kibwezi District, Makueni County, Kenya
(Arts Humanit, 2015)
Ecosystems provide essential services like water regulation and other processes which sustain and fulfill human life by directly or indirectly supporting humans‟ survival and quality of life. However, there is insufficient ...
Intensity of farmland cultivated and soil bulk density in different physiographic units in Nyakach district
(Journal Of Humanities And Social Science, 2014)
A number of scholars agree that frequent cultivation raises soil bulk density through compaction and destruction of soil structure. However, no research has been conducted to establish how the intensity of farmland cultivated ...
