摘要：Surfactin is a lipopeptide of the biosurfactant class, most commonly produced by Bacillus subtilis, a Gram-positive bacterium. The chemical structure of surfactin is composed of peptide bound to carboxyl groups and hydrocarboxyl of long chain fatty acids. Surfactin production may be influenced by the strain, inoculum and age of the microorganism, as well as physical factors such as temperature, pH, agitation speed, aeration degree, foam formation and dissolved oxygen concentration and nutritional factors, such as carbon, nitrogen and trace elements in the culture media. The potential areas of application of this biosurfactant are therapeutic and environmental. This work aims to address structural aspects, factors involved in production by microorganisms and the application areas of surfactin.
