Nucleotide sequence and mutational analysis of an immunity repressor gene from Bacillus subtilis temperate phage ϕ105 [PDF]
We have identified and sequenced a bacteriophage phi 105 gene encoding an immunity repressor, the first to be characterized from a temperate phage infecting a Gram-positive host.

This study engineered a Pseudomonas putida strain to efficiently remove sulfur from dibenzothiophene (DBT) by reordering and optimising the dsz operon from Rhodococcus qingshengii IGTS8, enhancing catalytic activity and stability. The modified strain, P. putida DS006, showed high desulfurization efficiency in model biodesulfurization systems.

Engineering Gram-Negative Microbial Cell Factories Using Transposon Vectors [PDF]
The construction of microbial cell factories à la carte largely depends on specialized molecular biology and synthetic biology tools needed to reprogram bacteria for modifying their existing functions or for bestowing them with new-to-Nature tasks.

Expanding the diversity of mycobacteriophages: Insights into genome architecture and evolution [PDF]
Mycobacteriophages are viruses that infect mycobacterial hosts such as Mycobacterium smegmatis and Mycobacterium tuberculosis. All mycobacteriophages characterized to date are dsDNA tailed phages, and have either siphoviral or myoviral morphotypes ...

Mediator‐based extracellular electron transfer in Pseudomonas putida KT2440 relies on the TonB‐dependent system for effective mediator (ferricyanide) transport. Transcriptomic and functional analyses confirmed its key role, while OprF overexpression enhanced membrane permeability and current output. These findings clarify mediator uptake mechanisms and

Mathematical modelling of CRISPR-Cas system effects on biofilm formation
Clustered regularly interspaced short palindromic repeats (CRISPR), linked with CRISPR associated (Cas) genes, can confer adaptive immunity to bacteria, against bacteriophage infections.

What makes the lac-pathway switch: identifying the fluctuations that trigger phenotype switching in gene regulatory systems [PDF]
Multistable gene regulatory systems sustain different levels of gene expression under identical external conditions. Such multistability is used to encode phenotypic states in processes including nutrient uptake and persistence in bacteria, fate ...

THE ESTABLISHMENT OF LYSOGENICITY IN ESCHERICHIA COLI [PDF]
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.

ABSTRACT Bacteriophages, or phages (viruses of bacteria), play significant roles in shaping the diversity of bacterial communities within the human gut. A phage‐infected bacterial cell can either immediately undergo lysis (virulent/lytic infection) or enter a stable state within the host as a prophage (lysogeny) until a trigger event, called prophage ...

ABSTRACT Shiga toxin‐producing Escherichia coli (STEC) are pathogenic E. coli strains that have been associated with a wide range of human clinical illness ranging from mild diarrhoea to bloody diarrhoea (BD) and haemolytic uremic syndrome (HUS). In its opinion of 18 May 2017, the French Agency for Food, Environmental and Occupational Health and Safety
