Isolation and identification of PNP-A homologues from Xerophyta viscosa Baker
(University of the Western Cape, 2004)Maintenance of growth, development and normal physiological processes remains crucial for the survival of plants. Plant hormones are described as integrators of external signal and internal developmental process in plants. ... -
Isolation and Partial Characterization Serine Protease Inhibitors from Triticum aestivum cv' Witwol
(University of the Western Cape, 2001)Plant diseases and plant pests are major constraints to plant growth and development, resulting in severe crop losses annually. Plant pathogens can be a variety of things, living and non-living. Non-living pathogens exist ... -
Isolation and preliminary characterization of bacteriophages of thermophilic Bacillus and Geobacillus species
(University of the Western Cape, 2015)Thermophilic bacteriophages provide simple model systems for understanding biochemical and biological adaptation mechanisms at elevated temperatures. The essential objectives of this study were to characterise the ... -
Isolation, expression, purification and characterisation of a novel acetyl xylan esterase from streptomyces species ORS10
(University of the Western Cape, 2012)Lignocellulosic biomass represents an important renewable resource for biofuels production. Lignocellulosic biomass is comprised of cellulose, hemicellulose and lignin. Lignocellulosics are highly recalcitrant to enzymatic ... -
Isolation, identification and characterisation of novel actinobacteria from Zambian hot-springs
(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 ... -
Isolation, identification and characterization of novel actinomycetes from Antarctic soil samples
(University of the Western Cape, 2008)Actinomycetes are Gram-positive bacteria that form filamentous branching hyphae with asexual spores. They occur in a variety of environments and are important industrially and pharmaceutically. The aims of this study were ... -
Isothermal and non-isothermal comparative study of Zn-sn system using real-time RBS
(2021)Solid-state reactions of bi-metallic systems can be driven or activated by various external stimuli like pressure, energetic photons, energetic charged particles or heat. For an example, high pressure torsion can be ... -
Isothermal and non-isothermal comparative study of zn-sn system using real-time rbs
(University of the Western Cape, 2021)Insight into the effects of isothermal and non-isothermal annealing on bi-metallic thin film is important for material synthesis and application in everyday use. The effects of isothermal annealing on bi-metallic thin ... -
Iterative helical real-space reconstruction of histone octamer tubular crystals and implications for the 30 nm chromatin fiber
(University of the Western Cape, 2006)This thesis investigated the helical structure of core histone octamers to discover interacting surfaces and their relevance to the compaction of nucleosome arrays into the chromating fiber. -
KernTune: self-tuning Linux kernel performance using support vector machines
(University of the Western Cape, 2006)Self-tuning has been an elusive goal for operating systems and is becoming a pressing issue for modern operating systems. Well-trained system administrators are able to tune an operating system to achieve better system ... -
