Abstract

SUMMARY

Two methods were developed to demonstrate a small fraction (10) of phage-sensitive cells in a phage-resistant population with a high degree of accuracy, using the plexiglass phage titration method (Horváth & Alföldi, 1954).

Phage-sensitivity was transferable by DNA isolated from 168 (SPO-1 phage-sensitive) to the recipient strain of 168 (SPO-1 phage-resistant) in transformation experiments. The number of 168 transformants was a function of the concentration of the transforming DNA. The and characters are not linked. The competence curves for the number of 168 and 168 transformants were similar. The phenotypic lag was found to be 5 hr 30 min. The maximum frequency of 168 cells among the transformants was 2 to 5 %.
