Acridine-resistant mutants of T2H bacteriophage.
mechanisms which prevent formation of infective T2H bacteriophage in T ~ c h r i c h i a coli in the presence of acridine dyes are unknown. That interruption of normal maturation occurs in a late stage of phage development was suggested by the work of FOSTER (1948) and has been substantiated physiologically and cytologically. DEMARS, LURIA, FISHER and LEVINTHAL ( 1953) and DEMARS (1955) found i...
متن کاملFurther characterization of the recipient ability of Escherichia coli K-12 bacteriophage-resistant mutants.
We extended the study of Escherichia coli mutants defective in conjugation and showed that the mutants with altered lipopolysaccharide, which are defective as recipients with F-like donors, are also defective with the I-like plasmid R64-11. However, the extent of reduction in recipient ability for I-like donors does not correlate either with the effect on recipient ability for F-like donors or ...
متن کاملLipopolysaccharide-deficient, bacteriophage-resistant mutants of Escherichia coli K-12.
Bacteriophage-resistant mutants isolated and classified in a previous study were examined for alterations in their lipopolysaccharide (LPS) composition, and properties likely to be affected by alterations in LPS composition were studied. It was found that many of the mutants of the Ktw (K2-resistance), Ttk (T2, T4, or K19 resistance), Bar (bacteriophage), Wrm (wide-range mutants), and miscellan...
متن کاملthe effect of functional/notional approach on the proficiency level of efl learners and its evaluation through functional test
in fact, this study focused on the following questions: 1. is there any difference between the effect of functional/notional approach and the structural approaches to language teaching on the proficiency test of efl learners? 2. can a rather innovative language test referred to as "functional test" ge devised so so to measure the proficiency test of efl learners, and thus be as much reliable an...
15 صفحه اولUse of trypsin to increase bacteriophage yield and to facilitate the isolation of bacteriophage-resistant mutants.
Lysis of bacteriophage-infected cells is often accompanied by the release of excess phage-induced lytic enzyme into the medium. Presumably, this enzyme facilitates lysis from within at the termination of the latent period, although details of the mechanism are lacking. The release of this enzyme by the first cells to lyse can cause premature lysis of the remaining cells, thus resulting in a red...
