Integrated process for production of surfactin [PDF]
Biochemical Engineering Journal, 2007 Previous work has presented kinetics of pure surfactin adsorption onto activated carbon. Being an efficient biosurfactant, the lipopeptide surfactin has been produced in a bioprocess supported by the strain Bacillus subtilis ATCC 21332.

Surfactin and surfactin-like production, purification, and application at marine environments
, 2022 Surfactin, a biosurfactant with great activity on interfaces, have been reported as a great substitute to non-renewable sources, non-biologically synthesized surfactants.

Isolation and characterization of a new variant of surfactin, the [Val7]surfactin [PDF]
European Journal of Biochemistry, 1991 Reinvestigation of surfactin, a previously studied peptidolipid surfactant from Bacillus subtilis, by fast‐atom‐bombardment mass spectrometry and 1H‐NMR spectroscopy, as well as by chemical methods, revealed the presence of a closely related second constituent. This new compound, [Val7]surfactin, differs from the known surfactin by the C‐terminal amino

Interactions of surfactin with membrane models
Biophysical Journal, 1995 Surfactin, an acidic cyclic lipopeptide produced by strains of Bacillus subtilis, is a powerful biosurfactant possessing biological activities. Interactions of ionized surfactin (two negative charges) with lecithin vesicles have been monitored by changes in its CD spectra. These changes are more important in the presence of Ca2+ ions.

Energies, 2020 Surfactin, which is an anionic bio-surfactant, can be effective for enhanced oil recovery because it decreases interfacial tension between oil and water. However, it forms precipitation by binding with divalent cations.

Characterization of the NRPS operon homolog for surfactin A and surfactin C synthesis in Bacillus spp. [PDF]
Characterization of the NRPS operon homolog for surfactin A and surfactin C synthesis in Bacillus spp.Surfactin is a cyclic lipopeptide produced by Bacillus spp., consisting of a β-hydroxy fatty acid and a heptapeptide synthesized by non-ribosomal peptide synthetases. Surfactin congeners (A, B, and C) differ in amino acid substitutions, with Leu7 in surfactin A replaced by Val in B and Ile in C.

Synthetic surfactin analogues have improved anti-PEDV properties.
PLoS ONE, 2019 Surfactin has antiviral activity against various enveloped viruses by inhibiting viral membrane fusion. However, the potential utility of surfactin as an antiviral drug is limited by its cytotoxicity.

Bacillus subtilis Genome Reduction Improves Surfactin Production
FermentationBacillus subtilis ∆6 is a genome-reduced strain derived from the laboratory strain 168 through deletion of six prophages and AT-rich islands. The parental and the genome-reduced strains were edited to restore the capacity to synthesize surfactin ...

World Journal of Microbiology and Biotechnology, 2021 Lipopeptides are important secondary metabolites produced by microbes. They find applications in environmental decontamination and in the chemical, pharmaceutical and food industries. However, their production is expensive. In the present work we propose three strategies to lower the production costs of surfactin.
