Actinobacterial and archaeal diversity in lake Magadi, Kenya
Halimat, Olubukola Ibrahim (University of the Western Cape, 2013)Microorganisms of the class Actinobacteria and domain Archaea are interesting from a biotechnological perspective owing to their metabolic attributes as producers of secondary metabolites and resilience under harsh ... -
Analysis of ammonia-oxidizing bacteria associated with the roots of Proteaceae plant species in soils of Fynbos ecosystem
Cowan, D. A. (University of the Western Cape, 2005)Molecular methods were used to investigate the microbial diversity and community structure of ammonia-oxidizing bacteria (AOB) associated with the roots of the Proteaceae plant family. The identification of ammonia ... -
Eukaryotic diversity of miers valley hypoliths
Keriuscia Gokul, Jarishma (University of the Western Cape, 2012)The extreme conditions of Antarctic desert soils render this environment selective towards a diverse range of psychrotrophic microbial communities. Cracks and fissures in translucent quartz rocks permit an adequate amount ... -
Isolation, identification and characterisation of novel actinobacteria from Zambian hot-springs
Mavengere, Natasha Robertha (2011)Actinomycetes are ubiquitous in many environments such as soil, activated sludge and water.Besides the genus Streptomyces, which has been extensively exploited, members of other genera including Micromonospora have been ... -
Metagenomic analysis and characterization of microbial diversity from hydrothermal samples of El Tatio geyser field, Chile
Galada, Ncebakazi (University of the Western Cape, 2012)The El Tatio geyser field (ETGF) is the largest known geothermal field in Chile, forming part of a wide spectrum of extremophilic habitats in the country. The ETGF is NaCl rich, with high concentrations of toxic elements ... -
Microbial ecology of hot and cold desert edaphic communities
Makhalanyane, Thulani Peter (University of the Western Cape, 2012)This thesis presents significant advances into the microbial ecology of hypolithic communities in two hyperarid deserts. Deserts account for one fifth of the Earths total surface area. These zones differ substantially in ... -
Microbiology of fly ash-acid mine drainage co-disposal processes
Kuhn, Eloise M. R. (University of the Western Cape, 2005)The waste products acid mine drainage (AMD), formed during coal mining and fly ash (FA) from coal burning power generation, pose substantial environmental and economic problems for South Africa. Eskom has developed a ...
