Hypothesis
Are various Bacillus species potential riboflavin production hosts with low maintenance metabolism?
Conclusion
B. licheniformis T380B is the best choice for riboflavin production due to its low maintenance energy requirements and robust growth.
Supporting Evidence
- B. subtilis had the highest maintenance energy coefficient among the species studied.
- B. licheniformis T380B showed significantly reduced maintenance energy requirements.
- The spo0A mutation increased the maintenance metabolism of B. subtilis.
Takeaway
Some bacteria can make riboflavin, but one type, B. licheniformis T380B, is better at it because it uses less energy to stay alive.
Methodology
The study used chemostat cultures to analyze the maintenance metabolism and carbon fluxes of different Bacillus species.
Limitations
The maintenance coefficients for B. pumilus and B. subtilis natto could not be determined due to fluctuations in biomass concentrations.
