Temperate and chronic virus competition leads to low lysogen frequency [PDF]
arXiv, 2019 The canonical bacteriophage is obligately lytic: the virus infects a bacterium and hijacks cell functions to produce large numbers of new viruses which burst from the cell. These viruses are well-studied, but there exist a wide range of coexisting virus lifestyles that are less understood.

ChemBioChem, EarlyView.This study describes the successful identification of ancestral sequences N50 and N49, which have a longer half‐life of approximately four and two times the wild‐type Sp‐amine transaminase, respectively.. This approach effectively enhances the thermal stability of the transaminase.

Elementa: Science of the Anthropocene, 2018 Increasing human activity has raised concerns about the impact of deposition of anthropogenic combustion aerosols (i.e., black carbon; BC) on marine processes. The sea surface microlayer (SML) is a key gate for the introduction of atmospheric BC into the

Viruses, 2020 How microbial populations interact influences the availability and flux of organic carbon in the ocean. Understanding how these interactions vary over broad spatial scales is therefore a fundamental aim of microbial oceanography.

An HIV Feedback-Resistor: Auto-Regulatory Circuit Deactivator and Noise Buffer [PDF]
Weinberger LS, Shenk T (2007) An HIV Feedback Resistor:
Auto-Regulatory Circuit Deactivator and Noise Buffer. PLoS Biol 5(1): e9, 2007 Many viruses have the cunning ability to enter a hibernative or off state, termed latency or lysogeny. When in a latent state, the virus is unable to replicate, and its gene expression program is largely shut down. This facility for lying dormant typically ensures lifelong persistence of the virus in the host; it is also a particularly problematic ...

ChemElectroChem, EarlyView.A wireless, flexible potentiometric sensor equipped with gold and solid‐state electrodes continuously monitors potential changes to detect the microbial growth of E. coli, S. aureus, and P. aeruginosa in culture media. Ex vivo trials confirm the sensor's effectiveness in wound environments, highlighting its potential for point‐of‐care applications ...

Frontiers in Microbiology, 2017 Most analyzed Lactococcus lactis strains are predicted to harbor one or more prophage genomes within their chromosome; however, the true extent of the inducibility and functionality of such prophages cannot easily be deduced from sequence analysis alone.

ChemPhysChem, EarlyView.A novel and environmentally friendly photosensitive nanohybrid film made of chitosan and WO3MoO3 nanoparticles is prepared via a deep eutectic solvent‐assisted hydrothermal‐based method and a solvent casting protocol. The nanocomposite film shows a strong antibacterial effect on gram‐positive and gram‐negative cells, displaying cell viability above 90%

Insights into the Functions of a Prophage Recombination Directionality Factor
Viruses, 2012 Recombination directionality factors (RDFs), or excisionases, are essential players of prophage excisive recombination. Despite the essentially catalytic role of the integrase in both integrative and excisive recombination, RDFs are required to direct ...

A forward genetic screen identifies host factors that influence the lysis-lysogeny decision in phage lambda [PDF]
, 2017 The lysis‐lysogeny decision made by bacteriophage lambda is one of the classic problems of molecular biology. Shortly after infecting a cell, the virus can either go down the lytic pathway and make more viruses, or go down the lysogenic pathway and ...
