Growth of an aromatics‐overproducing Pseudomonas taiwanensis on adipate and 1,4‐butanediol was engineered for bio‐upcycling. Adaptive laboratory evolution followed by genome sequencing was used to identify and reverse engineer growth‐enabling mutations.

FimX, a multidomain protein connecting environmental signals to twitching motility in Pseudomonas aeruginosa [PDF]
Twitching motility is a form of surface translocation mediated by the extension, tethering, and retraction of type IV pili. Three independent Tn5-B21 mutations of Pseudomonas aeruginosa with reduced twitching motility were identified in a new locus which

Summary Cyanobacteria are major components of biofilms in light‐exposed environments, contributing to nutrient cycling, nitrogen fixation and global biogeochemical processes. Although nitrogen‐fixing cyanobacteria have been successfully used in biofertilization, the regulatory mechanisms underlying biofilm formation remain poorly understood.

The transcription factor AmrZ regulates genes important for P. aeruginosa virulence, including type IV pili, extracellular polysaccharides, and the flagellum; however, the global effect of AmrZ on gene expression remains unknown, and therefore, AmrZ may ...

The heme-based oxygen sensor Rhizobium etli FixL: influence of auxiliary ligands on heme redox potential and implications on the enzyme activity [PDF]
Conformational changes associated to sensing mechanisms of heme-based protein sensors are a key molecular event that seems to modulate not only the protein activity but also the potential of the Fe redox couple of the heme domain.

Genotypic and phenotypic characteristics of Cronobacter species, with particular attention to the newly reclassified species C. helveticus, C. pulveris, and C. zurichensis [forthcoming] [PDF]
In 2013, Enterobacter helveticus, E. pulveris and E. turicensis, were reclassified as Cronobacter helveticus, C. pulveris and C. zurichensis, respectively. Previously these species had been used as negative controls for some Cronobacter detection assays.

Second messenger-mediated tactile response by a bacterial rotary motor [PDF]
When bacteria encounter surfaces, they respond with surface colonization and virulence induction. The mechanisms of bacterial mechanosensation and downstream signaling remain poorly understood.

Comparative genomics of Aeschynomene symbionts : insights into the ecological lifestyle of nod-independent photosynthetic Bradyrhizobia [PDF]
Tropical aquatic species of the legume genus Aeschynomene are stem- and root-nodulated by bradyrhizobia strains that exhibit atypical features such as photosynthetic capacities or the use of a nod gene-dependent (ND) or a nod gene-independent (NI ...
