Survivability of strain WMA-LM9 isolated from desert soil following exposure to different energy levels of ultraviolet B (UV-B) radiation. a UV radiation-resistant potential of WMA-LM9, b resistance to different concentrations of hydrogen peroxide (H2O2; mM), c resistance to different concentrations of mitomycin C (μg/ml). Percentage survivability value is calculated as N1/N0 × 100 where Ni is the value after exposure to irradiation, H2O2 or mitomycin C, and N0 is the value at time 0, for each condition tested. Results are highly significant among different groups at p < 0.05 (Student’s unpaired t test). Values are given as the mean ± standard deviation (SD; error bars) of triplicate experiments
