The generation of biosurfactants

Surfactants and emulsifiers are used in the textile industry, in household cleaners, and cosmetics. Surfactants are either synthesized on the basis of fossil or of renewable raw materials. The structural diversity of chemically synthesized surfactants, however, is limited. Despite their structural diversity, so far biosurfactants produced by microorganisms are only found in few products. The project BioSurf aims at an increased replacement of petro-based surfactants by bio-based surfactants, which can be generated from renewable resources and are environmentally friendly. As part of the project BioSurf the Fraunhofer IGB with its project partners is developing surfactants from microorganisms as well as enzymatically produced surfactants based on renewable resources. By process improvement and the corresponding product preparation, biosurfactants will be economically manufactured and thus will be able to compete with conventional surfactants. • More: http://www.igb.fraunhofer.de/en/compe...
