Biosorption of cadmium from water using surfactant impregnated eggshell
Fosso-Kankeu, Elvis; Steenekamp, Gerhard; Akinpelu, Enoch; Waanders, Frans (EARET, 2018)Cadmium (Cd) is regarded as one of the most toxic elements and it causes water pollution when it exceeds the permissible limit. It is currently present in the Mooi River above these permitted levels, and must therefore ... -
Brewery effluent sludge characterization and dewatering to increase potential water recycling capabilities
Fosso-Kankeu, Elvis; Van der Vyver, Christiaan; Moyakhe, Dumisane; Waanders, Frans; De Klerk, Corli (EARET, 2018)In this study various coagulants and flocculants were tested for optimum removal of COD from brewery wastewater. The coagulants used were ferric chloride and an organic coagulant mixture obtained from the brewery company. ... -
Cloning of the cnr operon into a strain of Bacillaceae bacterium for the development of a suitable biosorbent
Fosso-Kankeu, Elvis; Mulaba-Bafubiandi, Antoine F.; Piater, Lizelle A.; Matsobane, G. Tlou (Springer, 2016)In this study, a potential microbial biosorbent was engineered to improve its capacity to remediate heavy metal contaminated water resources. A Bacillaceae bacterium isolated from a mining area was transformed with ... -
Column leaching of fine coal tailings: impact on environment and thickener operation
Moyakhe, Dumisane; Fosso-Kankeu, Elvis; Campbell, Quentin (EARET, 2018)The coal mining sector is synonymous with generating large quantities of waste. A comprehensive fraction of the waste is classified as fines (-500 µm) and ultrafine (-100 µm) particles, which accounts eleven per cent ... -
Comparative adaptation of B. subtilis and P. aeruginosa in diesel supplemented medium and impact on biodegradation potential
Fosso-Kankeu, Elvis; Marx, Sanette; Brink, Antonie (PSRC, 2014)The degree of diesel blending is likely to influence its toxicity as well as the susceptibility and speed of biodegradation. It is therefore imperative to identify strains that can degrade diesel blend in record time, such ... -
