Lo, Enlin published the artcilePhysiological insights into enhanced lipid accumulation and temperature tolerance by Tetraselmis suecica ultraviolet mutants, Name: Docosahexaenoic Acid, the publication is Science of the Total Environment (2022), 156361, database is CAplus and MEDLINE.
High outdoor temperatures significantly inhibit the growth and lipid production of the industrially promising marine microalga Tetraselmis suecica, which is viewed as a potential feedstock for high-value bioproducts and biofuels. To overcome this limitation, T. suecica was subjected to UV irradiation to generate mutants capable of being productive at higher temperatures The top two high-lipid mutants UV-25 and UV-31 isolated at 25°C and 31°C, resp., were compared to the wild type (WT) to delineate physiol. alterations and shed light on the mutants increased biomass and lipid productivity. At 25°C, UV-25 and UV-31 exhibited lipid productivity of 36.12 and 31.33 mg/L day, which were 1.4- and 1.2-fold higher than WT, resp. This increase in lipid biosynthesis correlated well with increased carotenoid content in UV-25 (2.2-fold) and UV-31 (3.6-fold), indicating an improved capacity to quench reactive oxygen species. At 31°C, the growth and lipid accumulation of UV-31 remained high, signifying adaptation to higher temperatures This is attributed to a well-coordinated modulation of the mutant’s cellular metabolism through an increase in galactose and phosphatidylglycerol levels, as well as in protein, all of which contributed to its performance at elevated temperatures The study successfully established a UV mutagenesis strategy for producing superior- performing microalgae strains with industrially desired traits, paving the way for future outdoor cultivation deployment.
