“…The same explanation may apply to the traces of rhamnose identified in the slime hydrolysates, since these two sugars have been identified in cell-wall fractions of P. aeruginosa (Salton, 1964;Clarke, Gray & Reaveley, 1967). In addition, aging cultures of P. aerugino8a produce a rhamnosecontaining glycolipid (Jarvis & Johnson, 1949;Edwards & Hayashi, 1965) and this may have been produced in small amounts by the cultures from which the slime was extracted, contributing to the rhamnose identified in the hydrolysates.…”

“…Microbial surfactants, which are secreted by different groups of bacteria, are composed of lipid, phospholipids, polysaccharide, protein and other biological macromolecules and contain various functional groups including carboxyl, amino and phosphate groups (Kosaric, 1992;Desai and Banat, 1997;Christofi and Ivshina, 2002). Pseudomonas aeruginosa, a Gram-negative bacterium, secretes rhamnolipids when grown under the appropriate conditions (Jarvis and Johnson, 1949). Rhamnolipids are a group of biosurfactants of glycolipid nature, composed of a hydrophilic head formed by one or two rhamnose molecules, known respectively as monorhamnolipid (monoRL) and dirhamnolipid (diRL), and a hydrophobic tail which contains one or two fatty acids.…”

“…Os primeiros relatos envolvendo a utilização de biossurfactantes datam de 1949, quando Jarvis e Johnson 9 detectaram as atividades antibiótica e hemolítica de um ramnolipídeo, e de 1968, quando Arima e colaboradores 10 descobriram a existência de um novo composto biologicamente ativo produzido por Bacillus subtilis 9 , o qual foi denominado surfactina devido à sua grande atividade superficial, tendo, posteriormente, sua estrutura elucidada 11 . Mais tarde, foi registrada a produção de biossurfactante em meios hidrofóbicos, o que levou a estudos de sua aplicação em tratamento de resíduos de petróleo 12 , recuperação de petróleo 13,14 , biorremediação e dispersão no derramamento de óleos 14 .…”
