Changes of lipid content and fatty acid composition of Schizochytrium limacinum in response to different temperatures and salinities

Optimization of Culture Conditions for Growth and Docosahexaenoic Acid Production by a Marine Thraustochytrid, Aurantiochytrium limacinum mh0186

“…This salinity tolerance of strain mh0186 was also consistent with that of A. limacinum SR21, although A. limacinum SR21 grew slightly at zero salinity 8,9) . The growth response of strain mh0186 with an exception of inorganic salt comprising artificial seawater is shown in .…”

“…The major fatty acids were palmitic acid (C 16:0 ) and DHA (C 22:6n-3 ), which accounted for 46.1% and 39.6% of the total fatty acids, respectively. This result is in good agreement with those reported for A. limacinum SR21 8,9) but different from those reported for Thraustochytrium species (T. aureum, T. roseum and T. striatum) that contained more C 18 fatty acids 25) . The total fatty acid content of the cell was 466.5 mg/g dry cells, and thus DHA yield was estimated as 4.3 g/L at 26 h in this study.…”

Growth, fatty acid profile in major lipid classes and lipid fluidity of Aurantiochytrium mangrovei Sk-02 as a function of growth temperature

“…strain mh0186, the amount of UFA and DHA decreased 1.2-times and at 1.3-times, when the temperature increased from 10 to 15°C, respectively (23). Similarly, in A. limacinum, the amount of DHA decreased from 37.6 to 24.8% of TFA but C16:0 increased from 38.0 to 41.6% of TFA when the cultivation temperature increased from 16 to 30°C (27).…”

“…showed the effect of temperature and salinity on the biomass and total fatty acid production (27). In a more recent study, the effect of temperature on growth and total fatty acid composition in Aurantiochytrium sp.…”

“…These results were in agreement with the trend reported for A. limacinum SR21 and Aurantiochytrium sp. strain mh0186, respectively (27,23). Hence, the regulation of the DPA versus DHA formation appeared to be quite different and it can be concluded that DPA was not a precursor for DHA as already suggested (20).…”
