Biosurfactant
production from industrial wastes with potential remove of insoluble paint
Biosurfactants are amphipathic compounds formed by a
hydrophilic and hydrophobic component, this characteristic confers to these
compounds the possibility of several applications. The production of
biosurfactants was evaluated through surface tension, emulsifying activity and character ionic. The biosurfactants
that presented lower surface tension and higher emulsifying activity were
applied in insoluble paint. The biosurfactants produced by both microorganisms
showed anionic character. The applied biosurfactants showed potential use in
solubilization and paint removal. Therefore, the residues of fish and sugarcane
bagasse showed efficient as carbon sources to obtain biosurfactants. In
addition, the preliminary paint removal application presented great results
that can be explored in the future.
