Abstract
- Colicins are released into the spent medium from colicinogenic cells. The pathway of release has been investigated in this study. The localization in producing cells of colicins A, E3 and of cloacin DF13 has been determined at various times after mitomycin C addition: no transient accumulation in the periplasmic space of colicinogenic E. coli K12 strains was detected by electron microscopy for any of the bacteriocins tested. Furthermore, asynchronous induction in individual cells was detected for each bacteriocin tested. These results strongly suggest that colicins, as well as cloacin DF13, do not transit through the periplasmic space before release from colicinogenic cells.
