PROCESS FOR PRODUCING A RHAMNOLIPID PRODUCED BY PSEUDOMONAS OR ENTEROBACTER USING ANDIROBA OR MURUMURU SEED WASTE

The process for obtaining rhamnolipids fromPseudomonas aeruginosaorEnterobacterusing andiroba or murumuru seed residue belonging to the field of monosaccharide radical-containing compounds consists of obtaining rhamnolipids by means of a biotechnological process that uses andiroba or murumuru seed residues after extraction of the oil thereof as a substrate forPseudomonas aeruginosaorEnterobacter hormaecheiorEnterobacter buriaestrains cultured in a bioreactor in a non-dispersive aeration system to reduce foaming, hence obtaining a rhamnolipid content of 10.5 g/L forPseudomonas aeruginosain stirred tank bioreactors under non-dispersive aeration, using microporous membranes, particularly silicone tubes, which allow oxygen supply by diffusion. This type of aeration allows for different configurations to be used, and in the exemplary embodiment of the invention the porous membrane/tube was located internally into the bioreactor liquor in the shape of a coil under the following process conditions: pure oxygen with pressure and flow rate suitable to maintain the O2pressure in the bioreactor at 20% over the first 24 hours of the assay and stirring in the range of from 300 to 700 rpm, using 2 radial impellers and manual configurations made as the dissolved oxygen concentration decreases.The obtained product has characteristics that cause it to be applied in the cosmetics industry owing to its emulsifying ability, stability and non-toxicity.
