Figure 4From: Expression of the heat shock gene clpL of Streptococcus thermophilus is induced by both heat and cold shockStreptococcus thermophilus SFi39 (black bars) and clpL Δ (gray bars) survival upon induction of heat shock (HS). Survival is reported as the percentage (y-axis) of colony-forming cells after the treatment compared to that after growth at 42°C (100%). Error bars indicate the coefficient of variation in three different experiments.Back to article page
