  1. 26. Lipid content and profile of Rhodotorula toruloides during fermentation

    University essay from SLU/Department of Molecular Sciences

    Author : Khairul Kibria; [2021]
    Keywords : Rhodotorula toruloides; fatty acids; lipid class; triglycerides; phospholipid; gas chromatography;

    Abstract : Oleaginous yeast such as Rhodotorula toruloides is a promising organism for production of lipids from lignocellulosic substrates. Microbial lipids have potential applications in energy, food, feed and pharmaceutical industry, because most of the lipids are triglycerides with long chain fatty acids that are comparable to typical vegetable oils and can be obtained without arable land requirement.
