ABSTRACT
A lipopeptide biosurfactant produced by Bacillus natto TK-1 has a strong surface activity. The biosurfactant was found to be an anti-adhesive agent against several bacterial strains, and also showed a broad spectrum of antimicrobial activity. The biosurfactant induced a significant reduction in tumor cells viability in a dose- dependent manner.
Um lipopeptídio biosurfactante produzido por Bacillus natto TK-1 apresenta intensa atividade de superfície. Verificou-se que o biosurfactante apresentou atividade antiadesiva contra várias cepas bacterianas, e também atividade antimicrobiana de amplo espectro. O biosurfactante causou uma redução significativa na viabilidade de células tumorais, de forma dose-dependente.
