• 2

  The expression of YFP with 2.5% oxygen concentration can reach to a relatedly high level. With the micro-aerobic promoter (Pvgb), its expression intensity at the exponential phase is 1.28. The PoPS of our device at 2.5% oxygen level is 13.9023.

The expression of YFP under micro-aerobic conditions (10%)

• 1
• 2

  The expression of YFP with 10% oxygen concentration can reach to a relatedly high level. With the micro-aerobic promoter (Pvgb), its expression intensity at the exponential phase is 1.24. The PoPS of our device at 10% oxygen level is 2.0653

PoPS of YFP and the expression level of YFP

  The YFP expression device has a micro-aerobic promoter, Pvgb. Its PoPS reaches the highest when the oxygen concentration is 2.5%. Under anaerobic or aerobic conditions,its PoPS is equal to 0 relatively.
