Genetic and functional characterization of the gene cluster directing the biosynthesis of putisolvin I and II in Pseudomonas putida strain PCL1445 [PDF]
, 2008 Pseudomonas putida PCL1445 secretes two cyclic lipopeptides, putisolvin I and putisolvin II, which possess a surface-tension-reducing ability, and are able to inhibit biofilm formation and to break down biofilms of Pseudomonas species including ...

Genotoxicity of cationic lipopeptide nanoparticles
Toxicology Letters, 2020 The genotoxicity of cationic lipopeptide nanoparticles (cLPNPs) was evaluated in vivo and in vitro comet assay and the in vivo chromosome aberrations test. In vitro comet assay, human blood cells were exposed to cLPNPs at the concentration of 2.5, 5, 10, 20, 40 and 100 μg/mL.

Viennamycins: Lipopeptides Produced by a Streptomyces sp. [PDF]
Journal of Natural Products, 2020 Extracts from Streptomyces sp. S4.7 isolated from the rhizosphere of edelweiss, an alpine medicinal plant, exhibited activity against Gram-positive bacteria. LC-HRMS analyses of the extracts resulted in the detection of two unknown, structurally related lipopeptides that were assumed to be responsible for the antibiotic activity. LC-MS guided isolation

Strategies for administration of biosurfactants-producing pseudomonads in closed hydroponic systems [PDF]
, 2011 Zoospore-producing oomycetes are major plant pathogens of particular concern in hydroponic systems. Compared with pesticides, biocontrol using antagonistic microorganisms is a sustainable approach to control oomycetes.

Lipid Selectivity of Fungicidal Lipopeptides [PDF]
Biophysical Journal, 2015 Cyclic lipopeptides act against a variety of pathogens and, thus, constitute highly efficient crop-protection agents. For example, commercially available fungicides contain mixtures of different Bacillus subtilis lipopeptide families, such as surfactins (SF), iturins (IT), and fengycins (FE).

Ultrashort antibacterial and antifungal lipopeptides [PDF]
Proceedings of the National Academy of Sciences, 2006 Host-defense cationic antimicrobial peptides (≈12–50 aa long) play an essential protective role in the innate immune system of all organisms. Lipopeptides, however, are produced only in bacteria and fungi during cultivation, and they are composed of specific lipophilic moieties attached to anionic peptides (six to seven amino acids).

The Iturin and Fengycin Families of Lipopeptides Are Key Factors in Antagonism of Bacillus subtilis Toward Podosphaera fusca [PDF]
, 2007 Podosphaera fusca is the main causal agent of cucurbit powdery mildew in Spain. Four Bacillus subtilis strains, UMAF6614, UMAF6619, UMAF6639, and UMAF8561, with proven ability to suppress the disease on melon in detached leaf and seedling assays, were ...
