Gluconic acid production by bacteria to liberate phosphorus from insoluble phosphate complexes [PDF]

, 2015
Ten indigenous bacterial isolates were identified as efficient mineral phosphate solubilisers namely 7 strains of Klebsiella pneumoniae, 2 strains of Enterobacter aerogenes and 1 strain of Pseudomonas aeruginosa. All the ten strains were able to dissolve

Bioinformatic evidence for a widely distributed, ribosomally produced electron carrier precursor, its maturation proteins, and its nicotinoprotein redox partners

BMC Genomics, 2011
Background Enzymes in the radical SAM (rSAM) domain family serve in a wide variety of biological processes, including RNA modification, enzyme activation, bacteriocin core peptide maturation, and cofactor biosynthesis.

Contrasting Methane, Sulfide and Nitrogen‐Loading Regimes in Bioreactors Shape Microbial Communities Originating From Methane‐Rich Coastal Sediment of the Stockholm Archipelago

Environmental Microbiology, Volume 27, Issue 2, February 2025.
In this study, microbial communities are enriched in brackish anoxic bioreactors with methane, sulfide, nitrate and ammonium. Novel diversity is identified and functionally analysed. ABSTRACT Coastal ecosystems are increasingly exposed to high nutrient loads and salinity intrusions due to rising seawater levels.

Ameliorative effects of pyrroloquinoline quinone on oxidized fish oil-induced growth retardation, immune suppression, and oxidative stress in yellow catfish Tachysurus fulvidraco

Aquaculture Reports
Fish oil is the primary oil source in aquafeeds, but is susceptible to oxidation during production and storage, thereby leading to oxidative stress in fish.

Engineered Passive Glucose Uptake in Pseudomonas taiwanensis VLB120 Increases Resource Efficiency for Bioproduction

Microbial Biotechnology, Volume 18, Issue 1, January 2025.
In this study, we heterologously expressed the energy‐independent glucose facilitator protein (Glf) from Zymomonas mobilis to replace the native energy‐demanding glucose transport systems, thereby increasing the metabolic energy efficiency. Implementation of passive glucose uptake in engineered production strains significantly increased product titres ...

Green and Enantioselective Synthesis via Cascade Biotransformations: From Simple Racemic Substrates to High‐Value Chiral Chemicals

Chemistry – An Asian Journal, Volume 19, Issue 19, October 1, 2024.
Enzymatic catalysis is a useful and greener alternative to classic chemical synthesis. This minireview provides an overview of enzymatic cascade reactions to convert cheap and readily available racemic substrates, such as racemic epoxides, alcohols, hydroxy acids, etc., into valuable chiral products in high ee and high yields.

The natural redox cofactor PQQ enables photocatalytic radical cyclizations

Photoenzymatic catalysis facilitates stereoselective new-to-nature chemistry under mild conditions. In addition to the rational design of artificial photoenzymes, naturally occurring redox enzymes have been repurposed for this approach. Most prominently, flavin-containing cofactors can promote photoredox catalysis in the chiral protein environment ...

Product Distribution of Steady–State and Pulsed Electrochemical Regeneration of 1,4‐NADH and Integration with Enzymatic Reaction

ChemistryOpen, Volume 13, Issue 8, August 2024.
This study investigates the direct electrochemical reduction of NAD+ for enzymatic cofactor regeneration. It discovers that dynamic conditions improve the short time selectivity towards 1,4‐NADH, but also result in the production of inactive by–products.

Unveiling the Broad Substrate Specificity of Deoxynivalenol Oxidation Enzyme DepA and Its Role in Detoxifying Trichothecene Mycotoxins

Toxins
DepA, a pyrroloquinoline quinone (PQQ)-dependent enzyme isolated from Devosia mutans 17-2-E-8, exhibits versatility in oxidizing deoxynivalenol (DON) and its derivatives.
