“…Control strains (Escherichia coli and Bacillus cereus), did not grow or produced any biosurfactant as measured by the methods of E24 and surface tension. All five strains were tested for haemolytic activity, which is regarded by some authors as indicative of biosurfactant production and used as a rapid method for bacterial screening (3,10,12). None of strains showed any haemolytic activity, indicating that the use of this rapid method could lead to reduced numbers of selected strains and potential losses of important active microorganisms.…”

“…Os ramnolipídios de P. aeruginosa e a surfactina (Figura 1) de B. subtilis funcionam como antibióticos, solubilizando os principais componentes das membranas celulares microbianas. Através da excreção destes biossurfactantes no meio, os microrganismos adquirem maior chance de sobrevivência e maior competitividade na busca por nutrientes 13 .…”

“…Os compostos ativos destas formulações são geralmente hidrofóbicos, sendo necessários agentes emulsificantes para dispersá-los em soluções aquosas 13 . Surfactantes de Bacillus foram utilizados para emulsificar formulações de pesticidas organofosforados imiscíveis 39 .…”

“…Nas últimas décadas, diversos microrganismos têm sido relatados como produtores de vários tipos de surfactantes. A biodegradabilidade 6,7 e baixa toxicidade dos biossurfactantes constituem vantagens adicionais sobre os ingredientes sintéticos e, conseqüentemente, tornam-se substitutos dos emulsificantes convencionais em alimentos e cosméticos 6 , originando maior apelo de mercado pelo fato desses produtos serem considerados naturais, além de apropriados para aplicação ambiental 7 .…”
