ROSERO, Neira-Gladys; PIMIENTA, Astrid-Lorely; DUGARTE, Fanny e CARVAJAL, Fredy-Gonzalo. PARAMETERS EXAMINATION OF A BIOSURFACTANT PRODUCTION AT LABORATORY SCALE. C.T.F Cienc. Tecnol. Futuro [online]. 2003, vol.2, n.4, pp. 42-34. ISSN 0122-5383.
This work presents the results obtained from the laboratory-scale experimentation for the optimization of production of rhamnolipid-type biosurfactant in a batch process, through the calculation and analysis of yield parameters. Different carbon/nitrogen ratios were studied, for which the production rates of rhamnolipid under nitrogen limitation was defined. Bacterial growth yield parameters YX/N and YX/C, were also calculated.
