Strain engineering and cultivation optimization of the yeast Yarrowia lipolytica for biotechnological processes
Abstract
Yarrowia lipolytica (Y. lipolytica) is an oleaginous and aerobic yeast, known for its ability to accumulate and store intracellular lipids, which can serve as potential feedstock for second-generation biodiesel production. Hitherto, strain and process engineering approaches have been employed to enhance lipid production and optimize the utilization of crude glycerol, a low-cost by-product of the biodiesel industry that is efficiently catabolized from the yeast. Despite substantial research on that topic, further improvements in white biotechnology are necessary to attain the desirable efficiency and sustainability. The aim of this thesis, is to contribute to a better understanding of the fermentation of Y. lipolytica in crude glycerol and its potential for SCO production. To achieve that, special emphasis is given on novel strain and process engineering techniques, to generate novel robust strains and optimize lipid extraction and fermentation processes, respectively. The review of the ...
