摘要：

The purpose of this study was to select microorganisms that were able to produce biosurfactants from fats and oils wastes generated by the food industry and restaurants. Soybean soapstock, chicken fat, hydrogenated vegetable fat and soybean frying oil were evaluated as alternative substrates. Pseudomonas sp. isolates LMI 6c and LMI 7a showed a capacity to utilize the substrates and to produce rhamnolipid surfactants. Soybean soapstock was considered the best substrate, generating 9.69 g.L-1 of rhamnolipids and a surface tension of 31 mN/m.
