FIG. 4.

Survival of “Ca. Glomeribacter gigasporarum” incubated in TY medium at 4°C (white symbols) and 28°C (black symbols). Three experiments were carried out with different initial bacterial densities, about 800 (diamond), 600 (triangle), and 300 (square) bacteria per μl. Numbers (Nb) of bacteria per microliter were estimated by counting bacteria on a Thoma cell in an aliquot of the bacterial suspension stained with Live/Dead bacterial viability kit stain. Each point is the mean of three independent tubes. Vertical lines correspond to standard errors of the means (n = 3).
