CAO, Xiao-Hong et al. Evaluation of a lipopeptide biosurfactant from Bacillus natto TK-1 as a potential source of anti-adhesive, antimicrobial and antitumor activities. Braz. J. Microbiol. [online]. 2009, vol.40, n.2, pp. 373-379. ISSN 1678-4405. http://dx.doi.org/10.1590/S1517-83822009000200030.
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.
