Abstract
This study evaluates the use of the capacitive coupled radio frequency double-pipe atmospheric-pressure plasma jet for the improvement of CoQ10 production from plasma treated Rhodobacter species UNLI-82 cells. This plasma jet can be ignited and sustained in both continuous and pulsed modes with different plasma carrier gases such as argon or helium. In this study, an argon carrier gas is fed through the atmospheric-pressure plasma source; oxygen reactive gas is injected into the plasma. The experimentally measured gas phase temperature of the atmospheric pressure plasma jet maintained was from 40 to 80°C, indicating this plasma jet to be low temperature plasma discharge. The atmospheric pressure plasma jet was used to create mutants of Rhodobacter species UNLI-82 by globally altering their metabolism and CoQ10 production. The cell mutant showed improved CoQ10 yield, which was increased by 25%. The possible mechanism is that atmospheric pressure plasma jet yield and oxidation state balance indicated that the cellular metabolism was changed by the mutation.
