Microbial cells can cooperate to resist high-level chronic ionizing radiation

Microbial cooperation under CIR.
a: Growth of EC1 in the presence or absence of 36 Gy/h for 2 days, either in pure culture or mixed in 1:1 co-culture with DR. b: As for panel A, but with DRkat- substituting for DR. The y-axis shows clonogenically viable cell concentrations normalized to 1 ml: the actual numbers of viable cells are 200 times smaller because only 5 μl of each species were used in these experiments. Dashed lines indicate cell concentrations under the assumption of no net proliferation.
