A model industrial workhorse: Bacillus subtilis strain 168 and its genome after a quarter of a century

open access: yesMicrobial Biotechnology, Volume 16, Issue 6, Page 1203-1231, June 2023., 2023
The reference genome of Bacillus subtilis was first sequenced and annotated 25 years ago. At that time, some 42% of the coding sequences could not be assigned a function. In the present annotated update, 15% of the CDS remain functionless. An important contribution of newly identitied functions has been attributed to nucleic acid modifying enzymes and ...

Mimicking prophage induction in the body: induction in the lab with pH gradients [PDF]

open access: yesPeerJ, 2020
The majority of bacteria within the human body are lysogens, often harboring multiple bacteriophage sequences (prophages) within their genomes. While several different types of environmental stresses can trigger or induce prophages to enter into the ...

Lysogenic pneumococci and their bacteriophages [PDF]

open access: yesJournal of Bacteriology, 1979
About half of pneumococci recovered from pediatric patients and one-third of isolates from adult patients yielded bacteriophages active against one or more of four noncapsulated indicator strains of pneumococcus. Strains of capsular types most frequently causing pediatric infections were associated with lysogeny.

Lysogenic Conversion of Rhizobium trifolii [PDF]

open access: yesJournal of General Microbiology, 1970
Surmmary Rhizobium trifolii strain SU 297, when lysogenized with phage 7 or its clear-plaque mutant 7cr, underwent lysogenic conversion that resulted in loss of ability to adsorb phages 7 and 7cr and the related phage 8. The same conversion was reflected in changes in the surface of the bacterium by which a somatic antigen, characteristic of the parent

The Phenomenon of Lysogenicity in Staphylococci [PDF]

open access: yesJournal of General Microbiology, 1949
SUMMARY: Of thirty coagulase-positive staphylococci, twenty-seven proved to be lysogenic. Free phage was found in filtrates of 4-5 hr. broth cultures of the lysogenic strains. The phages from six of these strains were examined by estimation of the amounts occurring in filtrates, for serology and for their range of lytic reactions with indicator strains.

High efficiency, restriction-deficient in vitro packaging extracts for bacteriophage lambda DNA using a new E.coli lysogen.

open access: yesNucleic Acids Research, 1993
Vectors carrying DNA modified in a mammalian host often do not propagate efficiently in E. coli due to bacterial restriction systems (1) capable of degrading DNA bearing a foreign methylation pattern. Restriction activity has been shown to interfere with

THE ESTABLISHMENT OF LYSOGENICITY IN ESCHERICHIA COLI [PDF]

open access: yesJournal of Bacteriology, 1953
When a population of sensitive bacteria is exposed to infection by a temperate phage, a large number of cells are not lysed and give rise to colonies containing lysogenic cells. Some of the factors influencing the probability that an infected cell of Escherichia coli, strain K12S, will give a lysogenic response are reported here.

Non-conventional therapeutic technique to replace CRISPR bacteria from biofilm by inducible lysogen

open access: yesJournal of Biological Dynamics, 2019
Bacteriophage can be an effective means of regulating bacterial populations when conditions allow phage invasion of bacterial colonies. Phage can either infect and lyse a host cell, or insert their DNA into the host cell genome; the latter process is ...

Bacteriophage 434 Hex Protein Prevents RecA-Mediated Repressor Autocleavage

open access: yesViruses, 2013
In a λimm434 lysogen, two proteins are expressed from the integrated prophage. Both are encoded by the same mRNA whose transcription initiates at the PRM promoter. One protein is the 434 repressor, needed for the establishment and maintenance of
