Imaging Shows How Bacteria Support Diverse, Nearby Colonies
With a novel technique that non-invasively analyzes microbes, scientists at Pacific Northwest National Laboratory profiled, for the first time, the chemicals that a cyanobacterium makes available to others. Over 4 days, Synechococcus sp. PCC 7002 steadily secretes two molecules that could be used as resources by other bacteria that are nearby. The technique that chemically profiles the microbial communities in both space and time is Nanospray Desorption Ionization Electrospray Mass Spectrometry, or nano-DESI. This instrument was built by Julia Laskin and her team at Pacific Northwest National Laboratory. This research graced the cover of Analyst.
