Cost-benefit analysis of the environmental impacts of Darvill Wastewater Works, Pietermaritzburg, KwaZulu-Natal.
(2002)
Darvill Wastewater Works (DWWW) receives and treats both domestic and industrial wastewater from the city of Pietermaritzburg, in KwaZulu-Natal. Sludge from the wastewater treatment is sprayed onto surrounding lands, causing ...
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 ...
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 ...
Isolation and identification of antibiotic producing microorganisms from natural habitats in the KwaZulu-Natal midlands.
(2001)
The search for new antibiotics continues in a rather overlooked hunting ground. In the course of
screening for new antibiotic-producing microorganisms, seventy-nine isolates showing
antimicrobial activity were isolated ...
Humic acid pretreatment for enhancing microbial removal of metals from a synthetic 'wastewater'.
(2004)
The presence of heavy metal ions in waste streams is one of the most pervasive
environmental issues of present times. A rotating biological contactor (RBC) was used
to investigate the potential capacity of microbial ...
Characterization of selected Bacillus isolates exhibiting broad spectrum antifungal activity.
(2004)
The genus Bacillus is comprised of Gram-positive, rod-shaped, spore-forming bacteria which are
well known for their ability to produce a diverse array of antimicrobial compounds. Ofparticular
interest is the ability of ...
The effect of water treatment residues on soil microbial and related chemical properties.
(2003)
Water treatment residue (WTR), a by-product of the water treatment process,
consists primarily of precipitated hydroxides of the coagulants used in the water
treatment process, along with sand, silt, clay, humic compounds, ...
Optimizing biocontrol of purple nutsedge (Cyperus rotundus).
(2006)
Cyperus rotundus L. CYPRO (purple nutsedge) and Cyperus esculentus L. CYPES (yellow
nutsedge) are problematic weeds on every continent. At present there is no comprehensive
means of controling these weeds.. ...
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 ...
