Efficient Optimization of Gluconobacter oxydans Based on Protein Scaffold-Trimeric CutA to Enhance the Chemical Structure Stability of Enzymes for the Direct Production of 2-Keto-L-gulonic Acid

Figure 2

The effect on temperature tolerance of G. oxydans after the expression of CutA. The symbols ■, ●, ▲, and ▼ represent the growth curve of G. oxydans/pGUC-tufB-cutA at 30°C, 37°C, 42°C, and 45°C, respectively. The symbols □, ○, △, and ▽ represent the growth curve of G. oxydans/pGUC at 30°C, 37°C, 42°C, and 45°C, respectively. Error bars represent the standard deviation of three biological replicates.
