Preparing this manuscript for submission to some journal we performed some additional controls and found that some of our key results may be in fact not reliable. The authors thus recommened not to use this work until an updated version is posted here.This applies to the data on nucleases activity and centricones usage. All the data on bacteriophage effects in the host cultures of different age were not reconsidered. We apologize for the inconvinience this may cause. Hope to update the MS version shortly.
