Development of a selection system for the detection of L-ribose isomerase expressing mutants of Escherichia coli [PDF]

, 2007
L-Arabinose isomerase (E.C. 5.3.1.14) catalyzes the reversible isomerization between L-arabinose and L-ribulose and is highly selective towards L-arabinose.

Genomic and Phenotypic Bases of Salt Tolerance in Sinorhizobium meliloti: Candidate Traits for Bioinoculant Development Addressing Saline Soils. [PDF]

Microb Biotechnol
Genome‐wide association analysis on 49 Sinorhizobium meliloti strains (21 de novo sequenced) reveals extensive phenotypic heterogeneity in salt tolerance, closely associated with quorum sensing, cell surface stability and adaptation. Salt‐tolerant strains exhibit a wider metabolic capacity, especially in carbon sources exploitation, underscoring their ...

Controlled functional expression of the bacteriocins pediocin PA-1 and bactofencin A in Escherichia coli [PDF]

, 2017
peer-reviewedThe bacteriocins bactofencin A (class IId) and pediocin PA-1 (class IIa) are encoded by operons with a similarly clustered gene organization including a structural peptide, an immunity protein, an ABC transporter and accessory bacteriocin ...

Redox linked flavin sites in extracellular decaheme proteins involved in microbe-mineral electron transfer [PDF]

, 2015
Extracellular microbe-mineral electron transfer is a major driving force for the oxidation of organic carbon in many subsurface environments. Extracellular multi-heme cytochromes of the Shewenella genus play a major role in this process but the mechanism
