Increasement of astaxanthin production from fresh Haematococcus pluvialis via the iron-catalyzed Haber-Weiss reaction under high temperatures |
| 초록 |
Photoautotrophic astaxanthin production using Haematococcus pluvialis has a variety of advantages ofpreventing bacterial contamination and augmenting astaxanthin titer and CO2 conversion. Although multipleadverse conditions to implement an increment in astaxanthin production werepreviously reported, high temperatures were not a feasible stress forefficacious photoautotrophic induction in our work. The ability of carotenogenesis washighly suppressed because the less reactive oxygenspecies (LROS; O2- and H2O2) were excessively generated athigh temperatures (30-36°C) in contrast to the more reactive oxygen species(MROS; O2 and OH•). This inefficientastaxanthin production was resolved by accelerating Iron-catalyzed Haber-Weissreaction to convert LROS into MROS, facilitating lipid peroxidation. The heatstress-driven Haber Weiss reaction will improve the photoautotrophic astaxanthinproduction from H. pluvialis under high temperatures via theratio control. |
