Optimization of your Induction Temperature and Substrate Delay Time to investigate the effect of culture temperature on enzyme activity, three temperaTo investigate the effect of culture temperature on enzyme activity, 3 temperatures (20 C, 28 C and 37 C) have been chosen for fermentation (Figure 3a). The conversion , ) 3a). efficiency of P2 3-carrying strain for E production at 37 37 waswas eight.46 0.43 (product efficiency of P2 3-carrying strain for E production at C 8.46 0.43 (item conconcentration was 17.92 0.92 g,-1), which was 1.3 times greater than that producedthe centration was 17.92 0.92 mg L-1L which was 1.3 times greater than that developed by by the P2-carrying strain in the exact same temperature. In the culture temperatureC, the converP2-carrying strain in the exact same temperature. In the culture temperature of 28 of 28 , the conversion efficiency of E 5-HT6 Receptor Modulator Accession created by the P2 3-carrying strain was as much as 12.92 0.59 sion efficiency of E produced by the P2 3-carrying strain was as much as 12.92 0.59 (product (item concentration was 27.36 .26 ), and-1), and also the conversion efficiency strain carryL concentration was 27.36 1.26 mg L-1 mgthe conversion efficiency on the from the strain ing P2 to generate E was E was 0.69 0.69 (item concentration was 21.35 -1 ). carrying P2 to generate ten.08 ten.08 solution concentration was 21.35 1.49 mg 1.49 Nevertheless, the quantity of item decreased, because the temperature was additional reduced to 20 C. At this temperature, the conversion efficiency of P2 3- and P2-carrying strains for E production was only 5.87 1.24 and three.45 0.74 (solution concentration was 12.43 2.63 mg -1 and 7.31 1.57 mg -1 ), respectively. This outcome MMP Formulation indicates that in specific temperature range, the production of bioactive protein increases together with the boost of temperature and reached the peak at the culture temperature of 28 C.Molecules 2021, 26,mg-1). Nonetheless, the quantity of item decreased, as the temperature was further reL duced to 20 . At this temperature, the conversion efficiency of P2 3- and P2-carrying strains for E production was only 5.87 1.24 and three.45 0.74 (product concentration was 12.43 2.63 mg-1 and 7.31 1.57 mg-1), respectively. This outcome indicates that of 13 L L 6 in particular temperature range, the production of bioactive protein increases with all the improve of temperature and reached the peak in the culture temperature of 28 .Figure Production of E in the corresponding substrate, N. The substrate (final concentration Figure 3. 3. Production of E in the corresponding substrate, N. The substrate (final concentration of of200 mg -1)) was added towards the cell culture in LB medium. (a): Conversion efficiency of E at various 200 mg-1 was added towards the L efficiency of E at unique induction temperatures. The strains had been induced for 8 h at 20 C, 28 C or 37 .(b): Conversion induction temperatures. The strains were induced for 8 h at 20 , 28 or 37 C.
