The conversion of a tol I11 Escherichia coli mutant, tolerant to colicins E2, E3, I a and K, into protoplast-like stable L-form makes i t sensitive to colicins E2, I a and K. I t s original sensitivity t o colicin El and tolerance to E3 are preserved in this celf form. Thus, rods of this mutant are
The inhibitive activity of colicins of 16 types (produced by 22 colicinogenic strains) on rods and protoplast-like stable L-formcellsof the strains Escherichia coli B, W1655 F' and W1655 Fwas compared. The results of 58 combinations tested fall into four groups (with three subgroups): 1) both cell f
