High-throughput isolation
of model microorganisms using (a,c,e)
Met–Leu–ACA and (b,d,f) Leu–Asp–ACA. (a,b)
Detection of DPP activity of the bacterial cell (P.
mexicana WO24) in WODLs. A total of about 3000 droplets
were analyzed by FADS. (b,c) High-throughput sorting of model microorganisms, P. mexicana WO24 (DPP-producing) and E. coli (DPP nonproducing). E. coli expressed RFP. A total of about 3000 droplets were analyzed by FADS.
Micrographs before merging are shown in Figure S13. (e,f) High-throughput isolation based on DPP activity
from suspensions containing two kinds of bacteria, P. mexicana WO24 and E. coli. In the pseudocolor plot of FADS, blue and green correspond to areas
of lower cell density, red and orange correspond to areas of high
cell density, and yellow corresponds to the mid-range. A total of
about 8000 droplets were analyzed by FADS. Micrographs before merging
are shown in Figure S14. All scale bars
in micrographs represent 100 μm.
