          Abstract

          Candida lipolytica IA 1055 produced extracellular biosurfactants with emulsification activity by fermentation using babassu oil and D-glucose as carbon sources. Natural seawater diluted at 50% supplemented with urea, ammonium sulfate, and phosphate was used as economic basal medium. The best results were achieved with the YSW-B2 medium, which contained urea, ammonium sulfate, and babassu oil and with YSW-B3 medium, which contained urea, ammonium sulfate, phosphate, and babassu oil, kept under fed batch fermentation for 60 hours with 5% of babassu oil. For the two media, the maximum specific growth rates were 0.02 h-1 and 0.04 h-1; the generation times were 34.6 h-1 and 17.3 h-1, and the emulsification activities were 0.666 and 0.158 units, respectively. The molecules of these new bioemulsifiers were contituted of carbohydrates, proteins and lipids.

A água do mar diluída a 50% suplementada com uréia, sulfato de amônio e fosfato foi usada como meio basal. Os melhores resultados foram atingidos com os meios YSW-B2 (contendo uréia, sulfato de amônio e óleo de babaçu)e YSW-B3 (contendo uréia, sulfato de amônio, fosfato e óleo de babaçu), através de fermentação em batelada alimentada com 5% de óleo de babaçu. A velocidade específica de crescimento foi de 0,02 h-1 e 0,04 h-1; tempo de geração de 34,6 h-1 e 17,3 h-1 e atividade de emulsificação igual a 0,666 e 0,158 unidades, respectivamente. As moléculas dos novos bioemulsificantes demonstraram ser constituídas por carboidratos, proteínas e lipídeos.
