Characterization of iturin a in antibiotics from various strains of Bacillus subtilis.

The Journal of Antibiotics, 1976
Iturin A, an antifungal lipopeptide characterized by the presence of homologous liposoluble beta-aminoacids was found to be the active component to bacillomycin B, bacillomycin R and eumycin. Iturin A was identified by thin-layer chromatography, aminoacid analysis and by characterization of liposoluble aminoacids and peptides. Another two preparations:

Characterization of a new antibiotic of iturin group: Bacillomycin D.

The Journal of Antibiotics, 1980
The characterization of an antibiotic isolated from a strain of Bacillus subtilis revealed that this compound is a new antifungal antibiotic of the iturin group. It contains a lipid moiety which is a mixture of 3-amino 12-methyl tridecanoic acid (40%) and 3-amino 12-methyl tetradecanoic acid (60%) and a peptide moiety: L-Asp1, D-Asp1, L-Glu1, L-Pro1, D-

Precursor-directed biosynthesis of fluorinated iturin A in Bacillus spp.

, 2012
Some iturin A-producing strains of Bacillus subtilis will elaborate the novel fluorinated analogue when incubated with 3-fluoro-L-tyrosine. The activity of iturin A is dependent on the D-tyrosine residue and the presence of fluorotyrosine may result in ...

Influence of the production of two lipopeptides, Iturin A and Surfactin S1, on oxygen transfer during Bacillus subtilis fermentation

, 1996
peer reviewedBacillus subtilis produces three types of lipopeptides: Iturins, Fengycins, and Surfactins. These amphiphilic molecules influence the volumetric oxygen transfer (K(L)a) like chemical surfactant.
