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.
(2020)Abstract available in pdf. -
Purification and characterization of catechol -1,2-dioxygenase from Acinetobacter sp. strain Y64 and Escherichia.coli transformants.
(2015)Abstract available in the print copy. -
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 ... -
Rapid prediction of multi-drug resistance in clinical specimens of Mycobacterium tuberculosis.
(2011)Conventional drug susceptibility testing techniques, the ‘gold standard’ for M. tuberculosis are slow, requiring about 3-6 weeks from a positive culture. This diagnostic delay, before initiation of appropriate treatment, ... -
Revival and characterization of aerobic endospore-forming bacteria from an ancient sediment core obtained from the Mfabeni Peatland, South Africa.
(2017)Abstract available in PDF file. -
The role of lens-derived signals in the development of the corneal endothelium.
(2013)Corneal endothelial development is an intricate process driven by finely tuned gene expression. Its formation is necessary for the continued normal development of the anterior segment of the eye. The presence of an ... -
Role of marine nitrifying bacteria in a closed system with Penaeus monodon.
(1984)In recent years there has been widespread interest in rearing aquatic organisms of nutritional and commercial value (Calaprice, 1976). The most hopeful prospect for marine prawn culture in the United Kingdom (Wickins, ... -
Screening for aerobic endospore-forming bacteria as biocontrol agents for powdery mildew disease of cucurbits.
(2015)Powdery mildew of cucurbits costs the South African cucurbit-growing industry millions of Rands per year in reduced yields and compromised fruit quality. Amongst the many bacterial and fungal antagonists of cucurbit powdery ... -
Screening for biosurfactant production amongst aerobic endospore forming bacteria isolated from Mfabeni peatland sediment core.
(2019)Abbstract available in pdf. -
Screening of fungal isolates for endoglucanase activity and cloning of a thermostable endoglucanase from phialophora alba.
(2016)Microbes are fast becoming the solution to the energy crisis. Alternative fuels that can be produced by microbes include bioethanol, biodiesel, methane and biohydrogen. This study aimed to identify and characterize a ... -
Screening, purification and characterisation of anti-pseudomonas aeruginosa compounds produced by endophytic fungi from Kigelia Africana.
(2018)The emergence of new diseases and drug resistant pathogens coupled with the side effects presented by conventional or synthetic drug use calls for the discovery of new antibiotics and chemotherapeutics. Pseudomonas aeruginosa ... -
Seasonal variation of microflora and their effects on the quality of wood chips intended for pulping.
(2013)Eucalyptus, pine and wattle are the predominant exotic wood species used in the production of dissolving pulp in South Africa. On entering the mill, wood is chipped and stored in outdoor piles where it becomes vulnerable ...
