The two types of biosurfactant-producing microorganisms,
P. aeruginosa ATCC-10145 and B. subtilis NCTC-
1040 were suitable for the biosurfactants production.
The strain P. aeruginosa ATCC-10145 could grow in the
culture medium containing glucose as the carbon source
better than the strain B. subtilis NCTC-1040 after 96 h.
The surface tension measurement indicated that the
production of biosurfactant by P. aeruginosa had better
surface activity than that produced by B. subtilis.
The rhamnolipid biosurfactant produced by P. aeruginosa
had antimicrobial activity against different species of
microorganisms. Thus the produced antimicrobial compound
can be further characterized and can be applied
as a biocontrol agent.
