Bacterial profiles analysed by REIMS using Xevo G2-XS

ABSTRACT:

Rapid evaporative ionisation mass spectrometry (REIMS) has been demonstrated capable of bacterial speciation by differentiation of their metabolic/lipidomic profiles. Previous work has shown the use of hand-held probes [1,2], and this dataset makes use of a robotic sampling probe which allows for high-throughput analysis [3]. This dataset consists of 651 isolates spanning 38 bacterial (564 isolates) and 6 (87 isolates) fungal species. Data are provided as Waters .raw and .mzXML files, with taxonomic and sample culturing information.
