Investigating control strategies to limit biofilm formation and/or quorum sensing by Aeromonas spp. isolates.
Aeromonas spp. are important biofilm-forming fish pathogens causing great economic loss in aquaculture. Bacterial cells within biofilms communicate with each other via the production of quorum sensing (QS) signalling ...
Partial purification and characterisation of Phialophora alba xylanases and its application to pretreated sugarcane bagasse.
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 ...
Modelling and optimization of microbial production of hydrogen on agro-municipal wastes.
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 ...
Genetic analyses of a Southern African millipede (Bicoxidens Attems 1928)
Bicoxidens Attems, 1928 is an afrotropical millipede in the family Spirostreptidae which constitutes nine species. Based on the analysis of the male copulatory organs known as gonopods, Bicoxidens is monophyletic. However, ...
Optimization of xylose and glucose yields from Napier grass (Pennisetum purpureum) using hybrid pretreatment and assessment for fermentative hydrogen production using immobilized cells.
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 ...
Seasonal variation of microflora and their effects on the quality of wood chips intended for pulping.
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 ...

Characterization of factors involved in and affecting biofilm formation by Aeromonas spp. Isolates.
Aeromonas spp. isolates, which are fish and opportunistic human pathogens, form biofilms, however the factors involved in and affecting biofilm formation have not been fully elucidated. Biofilm formation is affected by ...
Interaction between Mycobacterium tuberculosis and pulmonary epithelium.
Background Mycobacterium tuberculosis isolates such as the Beijing and F15/LAM4/KZN families dominate in patients. The emergence of extensively drug resistant (XDR) M. tuberculosis isolates raises concern. The need to ...
Strategies for effective bioremediation of water co-contaminated with 1, 2-dichloroethane and heavy metals.
The production of 1,2-Dichloroethane (1,2-DCA) exceeds 5.44 billion kg per year, and is higher than that of any other industrial halogenated chemical. Improper disposal practices or accidental spills of this compound have ...
