Avaliação de um lipopeptídio biosurfactante de Bacillus natto TK-1 com fonte potencial de atividade antiadesiva, antimicrobiana e antitumoral

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 dosedependent manner.
