Surfactin is a very powerful surfactant commonly used as an antibiotic. It is a bacterial cyclic lipopeptide, largely prominent for its exceptional surfactant power. Its amphiphilic properties help this substance to survive in both hydrophilic and hydrophobic environments. It is an antibiotic produced by the Gram-positive endospore-forming bacteria Bacillus subtilis. In the course of various studies of its properties, surfactin was found to exhibit effective characteristics like antibacterial, antiviral, antifungal, anti-mycoplasma and hemolytic activities.

  • Surfactin ist ein bakterielles Biotensid und Biozid, das als Antibiotikum verwendet wird. (de)
  • La surfactine est un lipopeptide synthétisé par voie non ribosomique appelée thiotemplate ou système NRPS. C’est un lipopeptide cyclique formé d’un peptide de 7 acides aminés de conformation D et L lié à un acide gras β-hydroxylé linéaire ou ramifié contenant de 13 à 15 atomes de carbone. C’est un composé amphiphile (responsable de son activité tensioactive) constitué d’une partie polaire hydrophile (peptide) et d’une partie apolaire hydrophobe (lipide). (fr)

  • Surfactina é um lipopeptídio surfactante produzido pela bactéria Bacillus subtilis. É dos mais poderosos biossurfactantes conhecidos, tendo a capacidade de reduzir a tensão superficial da água de 72 para 27 mN/m mesmo em baixas concentrações. Possui um das menores CMC dentre os biossurfactantes. Devido à sua elevada atividade superficial aliada à sua biodegradabilidade e baixa toxidez, é um dos mais estudados biossurfactantes sendo, portanto, apontado com potencial insumo para diversas setores industriais, ambientais, agrícolas e saúde.
