An Epidemiological study of gentamicin resistant gram negative bacteria with particular reference to pseudomonas aeruginosa at King Edward V111 Hospital, Durban
(1985)The sources of gentamicin resistant pseudomonads and enterobacteria were studied in detail. A total of 1703 gentamicin resistant gram negative bacilli (GRGNB) isolated from patients, staff and their immediate environment ... -
Quantification of fungal degradation of pinus patula and eucalyptus grandis.
(1992)Previous studies of fungal decay have mainly examined long term effects of wood decay. In contrast, the present work, was designed to quantify fungal degradation of wood during incipient decay. Three facultatively ... -
Molecular and biochemical characterisation of ethanolic D-xylose fermenting Pichia stipitis, Candida shehatae and their fusants.
(1994)No abstract available. -
Molecular characterisation and detection of xanthomonas albilineans, the sugarcane leaf scald pathogen.
(1994)No abstract available. -
A laboratory scale study to investigate the effects of solids concentration on the efficiency of anaerobic digestion.
(1995)With the exceptions of mixing and heating mechanisms, and the recycling of settled solids, no radical changes or improvements have been made to conventional anaerobic digesters treating municipal sewage. These digesters ... -
Development of a laboratory river model to determine the environmental impacts of key xenobiotic compounds.
(1996)Microorganisms are increasingly used in toxicological studies to determine potential environmental impacts of xenobiotic compounds. A multi-stage laboratory model was developed to facilitate the examination of environmental ... -
Installation, commissioning and preliminary microbiological and operational investigations of full-scale septic tank digestion of sewage.
(1997)This study investigated the commissioning and maintenance of a Pennells two-tank bioreactor system with specific reference to its application in rural areas of KwaZulu- Natal, South Africa to treat sewage and generate ... -
Exploitation of indigenous fungi in low-cost ex situ attenuation of oil- contaminated soil.
(1997)The central aim of this study was to determine if indigenous fungi of an oil-contaminated soil could be effectively used in a low-cost bioremediation of the soil. Since some of the contaminant had been present at the ... -
Application of image analysis in microecophysiology research : methodology development.
(1998)Rehabilitation of landfill sites is important for successful land utilization. Revegetation is one key element of the process since it can overcome aesthetic problems. The inimical challenges of landfill leachate and gas ... -
Analysis of microbial populations associated with a sorghum-based fermented product used as an infant weaning cereal.
(1999)The incidences of diarrhoeal episodes in infants and children have mostly been associated with the consumption of contaminated weaning foods. This is especially true in developing countries where factors such as the lack ... -
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 ... -
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 ... -
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 ... -
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, ... -
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 ... -
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.. ...
