Abstract: | Rhamnolipid biosurfactants are attracting attention due to their low toxicity, high biodegradability, and good ecological
acceptability. However, production in submerged culture is made difficult by severe foaming problems. Solid-state cultivation
(SSC) is a promising alternative production method. In the current work, we report the optimization of rhamnolipid production
by Pseudomonas aeruginosa UFPEDA 614 on a solid substrate containing sugarcane bagasse and corn bran. The best rhamnolipid production, 45 g/l of impregnating
solution used, was obtained with a 50:50 (m/m) mixture of sugarcane bagasse and corn bran supplemented with an impregnating
solution containing 6% (v/v) of each of glycerol and soybean oil. This level is comparable with those of previous studies
undertaken in solid-state cultivation; the composition of the biosurfactant is similar, but our medium is cheaper. Our work
therefore provides a suitable basis for future studies of the development of an SSC-based process for rhamnolipid production. |
