High-Throughput Fingerprinting of Rhizobial Free Fatty Acids by Chemical Thin-Film Deposition and Matrix-Assisted Laser Desorption/Ionization Mass Spectrometry

Abstract: Fatty acids (FAs) represent an important class of metabolites, impacting on membrane building blocks and signaling compounds in cellular regulatory networks. In nature, prokaryotes are characterized with the most impressing FA structural diversity and the highest relative content of free fatty acids (FFAs). In this context, nitrogen-fixing bacteria (order Rhizobiales), the symbionts of legumes, are particularly interesting. Indeed, the FA profiles influence the structure of rhizobial nodulation factors, requir… Show more

“…For example, the NFs of R. meliloti contain C16:2 and C16:3 FA moieties, while the NFs isolated from R. leguminosarum bv. viciae have various C16, C18:2, C18:3, and C18:4 residues [68,69]. This might indicate that the species-specific FAs are employed in the NF synthesis.…”

“…The main advantages of optical polymer fibers in comparison with glass are low weight, low price, and ease of use. , Apropos, recent works have appeared in which monolayers containing ions of transition metals and lanthanides are used as sorption materials. In particular, these works investigate similar materials as adsorbents for bioorganic analysis. Thin films transferred onto a substrate can act as metal-affinity sorbents. Such sorbents have an advantage because metals with an increased affinity for sites of biologically active macromolecules are accessible.…”
