Fig. 7From: Genomic characterization and radiation tolerance of Naganishia kalamii sp. nov. and Cystobasidium onofrii sp. nov. from Mars 2020 mission assembly facilitiesSurvivability of various yeasts exposed to UV-C radiation (doses: 0, 500, 1000, 2000 and 3000 J/m2. UV-C survival rates calculated using formula: N/N0, where N is the number of cells surviving at any given dose and N0 the number of cells of original seed culture (~ 2 × 104 cells/ml). The ratio of survival rates from three different species are plotted. The gray box shows the effect of desiccation and PVA treatment. The experiments were repeated twiceBack to article page
