Comprehensive utilization of the filamentous oleaginous microalga Tribonema utriculosum for the production of lipids and chrysolaminarin in a biorefinery concept

Previous studies have focused on the accumulation of lipid and palmitoleic acid in Tribonema spp., while chrysolaminarin produced by these filamentous oleaginous microalgae has rarely been reported. In this study, the effects of different initial nitrogen concentrations on the growth, lipid and chrysolaminarin accumulation of T. utriculosum were investigated, and the extraction route of lipid was also optimized, accompanied by the isolation and...
