@tasic_ljubica @LatinXChem So, there is structural difference and therefore we expect different properties, but we have not yet evaluated the characteristics of the surfactant.

[Fernanda Silva Ribeiro @fernanda_s_r]

@tasic_ljubica @LatinXChem The isoforms can also present a subdivision into homologous series, which vary in the number of carbon atoms that make up the lipid chain.

[Fernanda Silva Ribeiro @fernanda_s_r]

@tasic_ljubica @LatinXChem The identified lipopeptides can be divided into groups composed of cyclic peptides with different structures, such as surfactin and iturine. These groups are subdivided into isoforms, which differ in amino acid composition.

[Fernanda Silva Ribeiro @fernanda_s_r]

@tasic_ljubica @LatinXChem It would be possible to quantify lipopeptides through chemical characterization, using chromatograms, but we would need standards to build the calibration curves.

@tasic_ljubica @LatinXChem Hello, Ljubica! Thank you! MS: we used an UHPLC-MS/MS with a C18 column, in Electrospray Ionization mode + with a data dependent analysis method.

@saulobritto13 @LatinXChem Thank you, Saulo!

[Fernanda Silva Ribeiro @fernanda_s_r]

@saulobritto13 @LatinXChem In the research group, there are other students who are investigating the role of endophytic microorganisms and then one of the objectives is to evaluate the increase in resistance in plants.

@1LeticiaSR @LatinXChem Muito obrigada!

[Fernanda Silva Ribeiro @fernanda_s_r]

I'm grateful and very excited to participate in #LatinXChem2021. I want to invite you all to attend @LatinXChem tomorrow (20 Sept). My poster in #LatinXChemBio is "Metabolomic Chemical characterization of Bacillus with agricultural potential". See you! ⚛️
