Hi Patrick,

Thanks for your reply! I am familiar with the literature on Deinococcus, where Daly et al. propose that protection against radiation-induced oxidative damage to proteins is provided by manganese complexes. It is logical of course that resistance to oxidative stress and ionizing radiation are correlated. But I wonder is anything known specifically about radiosensitivity of metal-reducing and chemolithotrophic bacteria other than Shewanella oneidensis?

Hi Igor,

This is a little bit "Terra incognita" so far. There isn't universal mechanism for protection, used by bacteria (incl.CLT). First, we must define the type of radiation - a) UW light - one way is to produce enzymes, which have to deal with the dimmers (so called photoreactivation). b) ionizing radiation - CLT bacteria are similar to Micrococcus -have relatively high resistance due to complex reparation systems.
