FIG 3.
UV-C sensitivity and secondary metabolite profiles of ISS-isolated IF1SW-F4, CEA17, and their DHN-melanin mutants. (A) Percent viability following exposure to various doses of UV-C radiation for IF1SW-F4 and IF1SW-F4 ΔpksP. (B) Secondary metabolite profiles of IF1SW-F4 and IF1SW-F4 ΔpksP. (C) Percent viability following exposure to various doses of UV-C radiation for CEA17 and CEA17 ΔpksP. (D) Secondary metabolite profiles of CEA17 and CEA17 ΔpksP. Asterisks (*) indicate statistical significance using Welch’s corrected t test (details in Table S2).
