Abstract l‐Malate is a key flavor enhancer and acidulant in the food and beverage industry, particularly winemaking. Enzyme‐based amperometric biosensors offer convenience for monitoring its concentration. However, only a small number of off‐the‐shelf malate‐oxidizing enzymes have been used in previous devices. These typically have linear ranges poorly

A novel endo-hydrogenase activity recycles hydrogen produced by nitrogen fixation. [PDF]
BACKGROUND: Nitrogen (N(2)) fixation also yields hydrogen (H(2)) at 1:1 stoichiometric amounts. In aerobic diazotrophic (able to grow on N(2) as sole N-source) bacteria, orthodox respiratory hupSL-encoded hydrogenase activity, associated with the cell ...

Signaling by reactive molecules and antioxidants in legume nodules
Summary Legume nodules are symbiotic structures formed as a result of the interaction with rhizobia. Nodules fix atmospheric nitrogen into ammonia that is assimilated by the plant and this process requires strict metabolic regulation and signaling. Reactive oxygen species (ROS) and reactive nitrogen species (RNS) are involved as signal molecules at all

Soil microbial inoculants for sustainable agriculture: Limitations and opportunities
Abstract The burgeoning global market for soil microbial inoculants for use in agriculture is being driven by pressure to increase sustainable crop production by managing pests and diseases without environmental impacts. Microbial inoculants, based predominantly on bacteria and fungi, are applied to soil as alternatives to conventional inorganic ...

OhrR is a central transcriptional regulator of virulence in Dickeya zeae
OhrR is crucial for regulatory of virulence factors production and pathogenicity, and regulates SlyA and Fis to control the expression of downstream virulence genes. Abstract Dickeya zeae is the causal agent of rice foot rot disease. The pathogen is known to rely on a range of virulence factors, including phytotoxin zeamines, extracellular enzymes ...

New Insights into the Taxonomy of Bacteria in the Genomic Era and a Case Study with Rhizobia
Since early studies, the history of prokaryotes taxonomy has dealt with many changes driven by the development of new and more robust technologies. As a result, the number of new taxa descriptions is exponentially increasing, while an increasing number of others has been subject of reclassification, demanding from the taxonomists more effort to ...

Carbamoylation of Azorhizobial Nod Factors Is Mediated by NodU
Lipochitooligosaccharides (LCOs) synthesized by Azorhizobium caulinodans ORS571 are substituted at the nonreducing-terminal residue with a 6-O-carbamoyl group. LCO biosynthesis in A. caulinodans is dependent on the nodABCSUIJZnoeC operon.

Deciphering bacterial mechanisms of root colonization
Summary Bacterial colonization of the rhizosphere is critical for the establishment of plant–bacteria interactions that represent a key determinant of plant health and productivity. Plants influence bacterial colonization primarily through modulating the composition of their root exudates and mounting an innate immune response.
