Cell input modifications for GMD capture. Bacterial and algal concentrations were adjusted to cell concentrations OD600, OD750 in 1x PBS and 100 µl of the resultant cell suspension (or 50 + 50 µL for abGMDs) was used as cell input for initial capture in the CelGel Matrix prior to sorting. This ratio of bacteria-to-matrix or algae-to-matrix (# cells/GMD) was verified by microscopy; data not presented. “aGMD” = algae only GMDs, “bGMD” = bacteria only GMDs, “abGMD” = co-captured algal/bacterial GMDs.
