RESUMO
A mitomycin C-sensitive, mtc, mutant of Escherichia coli has an altered cell surface and is sensitive to sodium dodecyl sulfate (SDS). The mutant, M27, formed multinucleate nonseptated filaments in the presence of a low concentration of SDS (50 microgram/ml). When the culture grown at that concentration of SDS was diluted with an SDS-free medium, the filaments began to divide at a very rapid rate after a lag of about 20 min. Chloramphenicol inhibited this recovery division when added within 10 min after SDS dilution but did not inhibit the division when added 20 min after dilution. Penicillin G at a low concentration, which is enough to cause filamentation, had virtually no effect on the recovery division of SDS-induced filaments. The division of penicillin G-induced filaments was inhibited by SDS.
