The stability of prodigiosin under different conditions. (A) heat stability, prodigiosin was treated by different temperature(40, 60, 80°C); (B,C) pH stability, prodigiosin was treated under different pH condition(3, 4, 8, 9, and 10); (D) light stability, prodigiosin was illuminated in natural light for 4 h. All data were mean ± SD (n = 3). ∗∗represents statistical significance at p < 0.01.
