We describe an application of gel microdroplet (GMD) and flow cytometry techniques to selective enrichment of non‐growing Leuconostoc mesenteroides cells, which are well culturable on other media, from a mixture with Bacillus subtilis cells in nutrient broth. After encapsulating cells of the mixed population within GMDs and a brief incubation in nutrient broth, the inability of L. mesenteroides cells to form microcolonies within GMDs allowed their discrimination from B. subtilis cells. After staining the GMD mixture with 6‐carboxyfluorescein diacetate, which showed no influence on cell viability, the GMDs containing single cells of L. mesenteroides were selectively collected using flow cytometry sorting based on differences in fluorescence intensity. The cells of L. mesenteroides retained viability during the process.
