Pseudoxanthomonas taiwanensis and Pseudomonas thermotolerans: Novel Thermophilic Amylase Producers in Solid‐State Fermentation

Biotechnology and Bioengineering, Volume 122, Issue 12, Page 3503-3509, December 2025.
ABSTRACT Amylases are key industrial enzymes, and thermostable variants are particularly valuable for robust bioprocessing. This study investigates amylase production via solid‐state fermentation (SSF) using non‐sterile potato peel as substrate, comparing the performance of the autochthonous microbial population with that of the inoculated fungus ...

Glutamine Hydrolysis by Imidazole Glycerol Phosphate Synthase Displays Temperature Dependent Allosteric Activation

Frontiers in Molecular Biosciences, 2018
The enzyme imidazole glycerol phosphate synthase (IGPS) is a model for studies of long-range allosteric regulation in enzymes. Binding of the allosteric effector ligand N'-[5'-phosphoribulosyl)formimino]-5-aminoimidazole-4-carboxamide-ribonucleotide ...

Arginase from kiwifruit: properties and seasonal variation [PDF]

, 1988
The in vitro activity of arginase (EC 3.5.3.1) was investigated in youngest-mature leaves and roots (1-3 mm diameter) of kiwifruit vines (Actinidia deliciosa var. deliciosa) during an annual growth cycle, and enzyme from root material partially purified.

Thermostable Bacterial Esterases From Lipase Family 1.5 Degrade Compostable Polyesters PBAT and PBSA

MicrobiologyOpen, Volume 14, Issue 6, December 2025.
This study highlights that there is a broader diversity of enzymes with polyester depolymerase activity to be discovered from nature, beyond the well‐known PETases. We demonstrate that uncharacterized bacterial lipases possess polyesterase activity and thermostability, offering promising candidates for industrial plastic recycling without extensive ...

A Systematic Review and Meta‐Analysis of Randomized Controlled Trials on the Benefits of Using Lactobacillus Supplements as an Adjunct Treatment for Helicobacter pylori Eradication

MicrobiologyOpen, Volume 14, Issue 6, December 2025.
Lactobacillus supplementation, when used alongside triple or quadruple antibiotic therapy, significantly improved Helicobacter pylori eradication rates compared to placebo. Although reductions in adverse events and gastrointestinal symptoms were not statistically significant, strain variability limits conclusions regarding the specific efficacy of ...

The Thermococcales as a model system: historical perspectives and emerging tools

Journal of Bacteriology
Thermococcales are among the most widely studied hyperthermophilic Archaea and have become key models for understanding life at extreme temperatures. Early work in the 1980s culminated in the isolation of novel Thermococcales species from hydrothermal ...

A Survey of Protein Structures from Archaeal Viruses

Life, 2013
Viruses that infect the third domain of life, Archaea, are a newly emerging field of interest. To date, all characterized archaeal viruses infect archaea that thrive in extreme conditions, such as halophilic, hyperthermophilic, and methanogenic ...

Influence of Manure Application Techniques on the Microbial Content of Grass and Grass Silage

Grass and Forage Science, Volume 80, Issue 4, December 2025.
ABSTRACT Field observations of visible dry manure residues in organically fertilised grassland, especially in drought areas in Bavaria (Germany), raised questions about whether different manure application methods influence the microbial composition in grass and in silages.
