Time course of cell populations fractions of Pantoea sp. BM39, grown for 72 h on LB containing 40 ‰ (a) and 280 ‰ (b) of NaCl and stained with FDA and PI, as revealed by flow cytometry. Green line = FDA positive cells showing high viability; Light blue line = FDA and PI negative showing cells in latency; Dark blue line = FDA positive and PI positive showing cells starting to loose viability and to acquire PI; Red line = PI positive showing dead cells.
