- •
The promoter in front of the srfA operon was exchanged in two B. subtilis strains.
- •
A general enhancement of Surfactin production was not observed.
- •
Promoter substitution led to increased Surfactin yields in a minor producer strain.
- •
Product yields were reduced in a naturally strong Surfactin producer strain.
- •
Surfactin synthesis is differently regulated in minor and strong producer strains.
