Biotin fermentation optimal temperature
Webhours in duration. Within the two 3-hour lab periods we tested the effect of temperature on the respiration rates of wild type S. cerevisiae (BY741a). We tested a wide range of temperatures: 20˚C, 25˚C, 30˚C, 35˚C, and 40˚C. We used 35˚C as our control temperature since it is closest to the optimum temperature of 34˚C (Arroyo-Lopez et al ... WebThus, it can be suggested that the optimal fermentation temperature of WTC016 was 30 °C (Figure 6A), which is consistent with other strains of B. subtilis subsp. natto . As the optimal temperature for the cultivation of most Bacillus strains [ 45 ], 30 °C should be best for the microbial metabolism and the activities of related enzymes, which ...
