Proteomic Analysis of Scenedesmus Dimorphus Mutant with Higher Lipid Content

A mutant strain of the microalgae Scenedesmus dimorphus showed morphological changes and had higher growth rate compared to the wild type. In comparisons of lipid content between wild type and mutant using thin-layer chromatography, the content of triacylglycerol was markedly higher in the mutant strain. To define the metabolic changes in the mutant strain, 2-dimensional electrophoresis was conducted. Several proteins related to lipid synthesis and energy metabolisms were overexpressed in the mutant strain.
