Description
Summary:Agro-industrial by-products are being explored as alternative low-cost nutrients for various bioprocesses. In this work, the applicability of ram horn peptone (RHP) and waste frying oil were investigated for rhamnolipid production by Pseudomonas aeruginosa as the sole nitrogen and carbon sources, respectively. The rhamnolipid yield was considerably influenced by the type of organic nitrogen source. Among the tested organic nitrogen sources, RHP proved to be the best nitrogen source for both biomass and rhamnolipid production. RHP was also tested at different concentrations and 10 g/L RHP resulted in the greatest yield of rhamnolipid (12.1 g/L) in the presence of waste frying oil as the sole carbon source. These results revealed that rhamnolipid could be produced efficiently and cost effectively by P. aeruginosa OG1 using RHP and waste frying oil.
