Enteric-coated insulin microparticles delivered by lipopeptides of iturin and surfactin

Drug Delivery, 2018
Surfactin, a lipopeptide produced by Bacillus species, has been used for the oral delivery of insulin. In this study, another lipopeptide of iturin was tested for its ability to orally delivery insulin alone or plus surfactin.

New Cyclic Lipopeptides of the Iturin Class Produced by Saltern-Derived Bacillus sp. KCB14S006

Marine Drugs, 2016
Salterns, one of the most extreme natural hypersaline environments, are a rich source of halophilic and halotolerant microorganisms, but they remain largely underexplored ecological niches in the discovery of bioactive secondary metabolites. In continued

Antagonistic mechanism of iturin A and plipastatin A from Bacillus amyloliquefaciens S76-3 from wheat spikes against Fusarium graminearum.

PLoS ONE, 2015
Controlling toxigenic Fusarium graminearum (FG) is challenging. A bacterial strain (S76-3, identified as Bacillus amyloliquefaciens) that was isolated from diseased wheat spikes in the field displayed strong antifungal activity against FG.

Improving Iturin A Production of Bacillus amyloliquefaciens by Genome Shuffling and Its Inhibition Against Saccharomyces cerevisiae in Orange Juice [PDF]

Frontiers in Microbiology, 2018
Genome shuffling is an effective method for the rapid improvement of the production of secondary metabolites. This study used the principle of gene shuffling to enhance the yield of iturin A produced by Bacillus amyloliquefaciens LZ-5.

Surfactin and iturin A effects on Bacillus subtilis surface hydrophobicity [PDF]

Enzyme and Microbial Technology, 2000
The synthesis of extracellular molecules such as biosurfactants should have major consequences on bacterial adhesion. These molecules may be adsorbed on surfaces and modify their hydrophobicities. Certain strains of Bacillus subtilis synthesize the lipopeptides, which exhibit antibiotic and surface active properties.

An Economical Bioprocess for Lipopeptide Production From Bacillus subtilis. [PDF]

Microbiologyopen
The lipopeptide (LP) production potential of Bacillus isolates was evaluated against phytopathogenic fungi, with B. subtilis 4‐Ka‐22 identified as the top‐performing strain. Optimization of the production medium—comprising molasses, soybean meal, CaCl2, and glycerol—resulted in a 13.4‐fold increase in cell growth and over 99% cost reduction compared to
