Abstract
Whole Cell-matrix-assisted laser desorption / ionization-time-of-flight mass spectrometry (MALDITOF- MS) is an emerging sensitive technique for rapid typing of microorganisms, efficient screening of biocombinatorial libraries of natural compounds and the analysis of complex biological samples, as whole cells, subcellular particles, cell extracts and culture filtrates. It is unique to detect metabolites in-situ without the need to isolate and purify the investigated compounds. In favourite cases it enables in -situ structure analysis on the basis of the fragment pattern generated by postsource MALDI-TOF-mass spectrometry. The state of research of this methodology which has mainly been obtained by investigation of lipopeptides from bacilli and the large spectrum of bioactive peptides produced by cyanobacteria is reviewed. The potential of this innovative technique is demonstrated for the lipopeptides produced by various Bacillus subtilis strains.
