Phylogenetic diversity of nifH genes in Marion Island soil
(University of the Western Cape, 2006)
The microbial life of sub-Antarctic islands plays a key role in the islands ecosystem, with microbial activities providing the majority of nutrients available for primary production. Knowledge of microbial diversity is ...
Screening for subtate tolerant Geobacillus pallidus RAPc8 nitrile hydratase
(University of the Western Cape, 2009)
In this study G. pallidus RAPc8 NHase mutants were screened for reduced substrate inhibition compared to the wild type enzyme. Wild type and mutant enzymes were expressed and purified using hydrophobic interaction ...
Engineering homoaromatic substrate specificity into aliphatic-specific Geobacillus pallidus RAPc8 nitrile hydratase
(University of the Western Cape, 2007)
Geobacillus pallidus RAPc8 is a thermophilic nitrile-degrading isolate, obtained from thermal sediment samples of a New Zealand hot spring. The G. pallidus RAPc8 NHase gene has been cloned and expressed in E. coli. The ...
Monitoring of heavy metals in the bottelary river using typha capensis and phragmites australis
The aim of this study was to use plants to determine the degree of heavy metal contamination in water and sediments in order to effectively monitor and provide possible recommendation to improve the water quality in the ...
