Oxygen uptake rate (OUR) and respiratory quotient (RQ) are important for studying DHA production in Schizochytrium sp. HX-308, especially under conditions with limited dissolved oxygen.
In experiments with varying aeration rates in a 50L bioreactor, higher OUR was linked to better oxygen supply, resulting in a maximum biomass of 124.5g/L.
DHA content correlated strongly with RQ values, peaking at 44.85% of total fatty acids when RQ was highest, indicating active metabolic pathways, highlighting the potential of OUR and RQ for real-time monitoring of DHA fermentation processes.
Schizochytrium is an effective species for producing omega-3 docosahexaenoic acid (DHA). Here, we report a genome sequence of Schizochytrium sp. CCTCC M209059, which has a genome size of 39.
