The increasing use of terrestrial oils is associated with sustainability issues such as deforestation. Microbial oils, particularly from yeasts, are a promising alternative, provided they can be produced commercially. To this end, robust oleaginous yeasts with high growth rates are required. Metschnikowia pulcherrima is a robust oleaginous yeast with processing advantages such as exhibiting antimicrobial activity, growing at a low pH and in the presence of fermentation inhibitors - however, to date, relatively low growth rates and yeast biomass concentrations have been reported. To facilitate commercialisation of M. pulcherrima oils, the industrial relevance of this promising, but relatively under-explored oleaginous yeast, must be advanced. In this thesis, this was attempted through better understanding the physiology of the yeast under various operational conditions. The focus was on improving the fermentation growth rates, lipid productivity and yeast biomass concentration with the aim to produce a palm oil substitute.
