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 ... -
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 ... -
A microfluidics system for drug susceptibility testing in mycobacterium smegmatis.
(2015)Tuberculosis remains a major health concern worldwide. The emergence of strains resistant to anti-tuberculosis drugs has further complicated management of this disease. In addition, the prolonged multidrug chemotherapy (6 ... -
Modelling and optimization of microbial production of hydrogen on agro-municipal wastes.
(2013)The indiscriminate use of fossil fuels has led to global problems of greenhouse gas emissions, environmental degradation and energy security. Developments of alternative and sustainable energy resources have assumed paramount ... -
Modelling of hydrogen production bioprocess using Artificial Neural Networks (ANN).
(2016)Abstract available in PDF file. -
Molecula characterization of chlamdia trachomatis isolates using sequence variation in the major outer membrane protein gene (OMP1) and evaluation of their susceptibility profile.
(2019)Chlamydia trachomatis infections are the most common bacterial sexually transmitted infections (STIs) in humans, worldwide. Due to asymptomatic nature of C. trachomatis, the need for sensitive, reliable and affordable ... -
Molecular and biochemical characterisation of ethanolic D-xylose fermenting Pichia stipitis, Candida shehatae and their fusants.
(1994)No abstract available. -
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 ... -
Molecular characterisation and detection of xanthomonas albilineans, the sugarcane leaf scald pathogen.
(1994)No abstract available. -
Optimization of xylose and glucose yields from Napier grass (Pennisetum purpureum) using hybrid pretreatment and assessment for fermentative hydrogen production using immobilized cells.
(2014)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 ... -
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.. ... -
Partial purification and characterisation of Phialophora alba xylanases and its application to pretreated sugarcane bagasse.
(2013)Xylan is the major component of hemicellulose and its degradation can be achieved through the hydrolytic action of microbial xylanases. Xylanases have an array of applications one being bioethanol production. The lack ... -
Phenotypic and genotypic characterization of Salmonella species isolated from treated wastewater effluents and receiving rivers in Durban.
(2013)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 ... -
The potential of waste sorghum (sorghum bicolor) leaves for bioethanol process development using Saccharomyces cerevisiae BY4743.
(2017)The limitations of first generation biofuels have prompted the quest for alternative energy sources. Approximately 60 million tonnes of sorghum are generated each year, with 90% being lignocellulosic waste, which is an ... -
Preliminary investigation of nutrient supplementation of, and heavy metal mobilization by, dual (phenol/activated sewage sludge) co-disposal with refuse.
(1999)Investigation of landfill co-disposal technology, with emphasis on nutrient supplementation and heavy metal mobilization, was made. For the purpose of this study, co-disposal is defined as the combined disposal of ... -
Prevalence, antibiogram and molecular characterization of methicillin-resistant staphylococcus aureus recovered from treated wastewater effluent and receiving surface water.
(2018)Inadequately treated wastewater effluent serves as a reservoir of potentially pathogenic bacteria and contributes to the spread of these organisms in the environment, including Staphylococcus aureus (S. aureus), a faecal ... -
Process development for biomass and lipid production from a local chlorella isolate using a miniature parallel raceway pond reactor.
