[Protective action of reactivating factor of Luteococcus japonicus subsp. casei toward cells of Escherichia coli reparation mutants inactivated with UV-light].
Reactivating factor (RF) from Luteococcus japonicus subsp. casei had a protective action on UV-irradiated cells of Escherichia coli AB1157 with a native reparation system and on cells of isogenic reparation mutants of E. coli UvrA-, RecA-, and PolA-: the effect resulted in multifold increase of survivability. Defense action of L. casei exometabolite is not connected with stimulating reparation systems in E. coli, and, probably, it is mediated by involvement of the exometabolite in the mechanism of cell division. RF did not provoke the reactivation of E. coli cells inactivated by UV-light.
