Characterisation of chlorinated-hydrocarbon-degrading genes of bacteria.
(2009)
1,2-dichloroethane (DCA) is one of the most widely used and produced chemicals of the modern world. It is used as a metal degreaser, solvent, chemical intermediate as well as a fuel additive. This carcinogen is toxic to ...
Microbial biotransformation of kimberlite ores.
(2008)
Microbial leaching plays a significant role in the natural weathering of silicate containing
ores such as diamond-bearing kimberlite. Harnessing microbial leaching
processes to pre-treat mined kimberlite ores has been ...
Application of bacterial bioflocculants for wastewater and river water treatment.
(2008)
Dyes are often recalcitrant organic molecules that produce a colour change and contribute to the organic load and toxicity of textile industrial wastewater. Untreated effluent from such sources is harmful to aquatic life ...
Molecular and physiological characterization of thiosulphate-oxidizing microbial associations prior to use in hydrogen sulphide biofiltration.
(2000)
Interacting microbial associations capable of utilizing thiosulphate as an energy
source were enriched/isolated from activated sludge, landfill site [mal covering soil and
soil from an acid mine water drainage site. The ...
Microbiologically influenced corrosion of steel coupons in stimulated systems : effects of additional nitrate sources.
(2013-11-25)
Microbiologically Influenced Corrosion (MIC) is a process influenced by microbial presence and their metabolic activities. This study examined the microbial effects on metal corrosion under different environmental conditions ...
The microbiological assessment of a biofiltration system in KwaZulu-Natal (South Africa) treating borehole water containing Mn (II) and Fe (II).
(2013)
In the following study, the potential role that microorganisms play in the removal of Mn (II) and Fe (II) was assessed using biofilter sand and water samples collected from a biofiltration system (operated by Umgeni Water ...
Investigation into the diversity of antifungal aerobic endospore-forming bacteria associated with bulk and crop rhizosphere soil.
(2011)
Members of the genus Bacillus are mainly Gram positive, aerobic rod shaped, endospore-forming bacteria that are increasingly being recognised for their ability to promote plant growth and antagonise fungal pathogens. From ...
Optimization of xylose and glucose yields from Napier grass (Pennisetum purpureum) using hybrid pretreatment and assessment for fermentative hydrogen production using immobilized cells.
(2015-11-18)
The dependence on non-renewable fossil fuels has led to the depletion of these energies and global warming. Thus there is a need to search for sustainable energy sources to mitigate these challenges. Lignocellulosic biomass ...
Phenotypic and genotypic characterization of Salmonella species isolated from treated wastewater effluents and receiving rivers in Durban.
(2015-01-14)
Salmonella and Shigella spp. are major pathogens of humans and they cause diseases ranging from mild food poisoning to chronic diarrhoea, especially in children under the age of 5. They are commonly found in the gastrointestinal ...
