About this Research Topic
Investigation of microbial physiology and metabolism deciphers the mechanism of lipogenesis in the highly productive oleaginous strains. The advancement of systems biology provides “big picture” information including the global gene programs, protein profiles, or metabolomics underlying the lipid overproduction observed. Bioprocess has been developed for lipid production by cultivation of oleaginous strains on diverse renewable feedstock including lignocellulosic sugars, and more recently the substrate ranges for microbial lipid production were broadened to include lignin-derived compounds. The development of a comprehensive molecular toolbox allows for more efficient genetic manipulation of the selected non-conventional oleaginous strains as emerging microbial chassis towards biosynthesis of lipid-based chemicals and biofuels.
Although great accomplishments have been achieved in this significant field, there is no specific issue in a refereed journal focusing on microbial physiology, metabolism, and applications of oleaginous strains. To fill the knowledge gaps, this Research Topic aims to provide an effective communication platform to update the advancement in systematic understanding of metabolism, bioprocess development, synthetic biology tools and approaches, and metabolic engineering of oleaginous strains. It will provide a deep insight on metabolic regulation and microbial physiology in oleaginous strains, especially pertaining to lipid synthesis, and further represent an essential landmark in novel cell factory design and engineering, with particular emphasis on biosynthesis of lipid-based bioproduct and biofuels.
