Journal ArticleDOI
Chemotaxonomic Identification of Single Bacteria by Micro-Raman Spectroscopy: Application to Clean-Room-Relevant Biological Contaminations
Petra Rösch,Michaela Harz,Michael Schmitt,Klaus-Dieter Peschke,Olaf Ronneberger,Hans Burkhardt,Hans-Walter Motzkus,Markus Lankers,S. Hofer,Hans Thiele,Jürgen Popp +10 more
TL;DR: The first results of single-particle micro-Raman measurements in combination with a classification method, the so-called support vector machine technique, allowing for a fast, reliable, and nondestructive online identification method for single bacteria.
Journal ArticleDOI
Vibrational spectroscopy--a powerful tool for the rapid identification of microbial cells at the single-cell level.
TL;DR: This short review of vibrational spectroscopic advances in microbial identification of yeast and bacterial cells for bulk environment and single‐cell analysis is discussed.
Journal ArticleDOI
Micro-Raman spectroscopic identification of bacterial cells of the genus Staphylococcus and dependence on their cultivation conditions
TL;DR: This work has shown that micro-Raman spectroscopy in combination with a support vector machine is an extremely capable approach for a fast and reliable, non-destructive online identification of single bacteria belonging to different genera.
Journal ArticleDOI
Raman spectroscopic identification of single yeast cells
TL;DR: First results of micro-Raman analysis together with a hierarchical cluster analysis allowing for an online identification method for yeast cells at a single-cell level are reported on.
Journal ArticleDOI
Direct analysis of clinical relevant single bacterial cells from cerebrospinal fluid during bacterial meningitis by means of micro-Raman spectroscopy.
Michaela Harz,Michael Kiehntopf,Stephan Stöckel,Petra Rösch,Eberhard Straube,Thomas Deufel,Jürgen Popp,Jürgen Popp +7 more
TL;DR: Investigation of a CSF sample obtained from a patient with meningococcal meningitis showed that the cerebrospinal fluid matrix does not mask the Raman spectrum of a bacterial cell notably since via chemometric analysis with HCA an identification of N. meningitidis cells from patients with bacterialMeningitis could be achieved.
