The Role of Soil Microorganisms in Microplastic Biodegradation: Mechanisms, Carbon Preferences, and Ecological Impacts

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 1, February 2026.
This work explores the complex relationship between soil carbon availability and microplastic biodegradation, highlighting competition and symbiosis among microorganisms, the repurposing of microplastic‐derived polymers, and the impact of soil organic carbon on microbial substrate preferences and carbon use efficiency variability.

Stabilizing behaviors of Pseudomonas putida and Pseudomonas alcaligenes bacteria on heavy metal ions in electrolytic manganese residue

open access: yesEcotoxicology and Environmental Safety
Electrolytic manganese residue (EMR) contains a significant amount of Mn ions as well as Zn, Cu and Cd ions, which have negative environmental impacts due to their toxicity. This study aims to investigate the effects of Pseudomonas putida (P. putida) and

Alcaligenes piechaudii from chronic ear discharge [PDF]

open access: yesJournal of Clinical Microbiology, 1988
A recently described bacterium, Alcaligenes piechaudii, was isolated repeatedly from the ear discharge of a diabetic man. This appears to be the first report of human infection in which there is clinical evidence of a pathogenic role for this species.

Polysaccharide Adjuvants as Innate Immune Trainers: Bridging Pattern Recognition Receptor (PRR) Activation and Metabolic Reprogramming for Synthetic Vaccine Design

open access: yesAdvanced Science, Volume 12, Issue 48, December 29, 2025.
Polysaccharides modulate immune responses by engaging pattern recognition receptors (PRRs) to induce T‐cell activation. In vaccine design, their particle size critically influences lymph node targeting and activation mechanisms. By engineering structural complexity and multivalent PRR engagement, polysaccharides enable precise modulation of immune ...

The kinetics of phenol degradation by immobilized pseudomonas sp in a repeated-batch process [PDF]

open access: yes, 2007
The best operating conditions for phenol degradation by immobilized Pseudomonas sp in packed column were determined, and then evaluated in repeated batch cultures. The maximum degradation rate occurred in i) the support with 1.0 cm diameter or less, ii)

Structure of the 2,4'-dihydroxyacetophenone dioxygenase from Alcaligenes sp. 4HAP. [PDF]

open access: yes, 2014
The enzyme 2,4'-dihydroxyacetophenone dioxygenase (DAD) catalyses the conversion of 2,4'-dihydroxyacetophenone to 4-hydroxybenzoic acid and formic acid with the incorporation of molecular oxygen. Whilst the vast majority of dioxygenases cleave within the

Dense autotrophic cultures of Alcaligenes eutrophus [PDF]

open access: yesApplied and Environmental Microbiology, 1976
Alcaligenes eutrophus was grown autotrophically in 23-liter batch cultures in a controlled H2-O2-CO2 atmosphere. It was demonstrated that the need for periodic supplements of individual nutrients could be anticipated before cell growth depleted these nutrients to the point of becoming growth rate limiting.

Chitosan, Gelatin, Aloe vera, and Carvacrol Nanoemulsion–Based Edible Coatings: Effects on Physicochemical, Microbiological, and Sensory Qualities of Vacuum‐Packed Chicken Fillets

open access: yesFood Bioengineering, Volume 4, Issue 4, Page 612-627, December 2025.
ABSTRACT Chicken meat contains high‐quality protein and is prone to postharvest quality deterioration due to high moisture and lipid content. Thus, in this study, edible coatings were developed from natural biomaterials, that is, chitosan (CH), gelatin (GL), Aloe vera gel (AVG), and carvacrol nanoemulsion (CNE), and their effects on shelf life of ...

Bacterial contamination of table eggs and the influence of housing systems [PDF]

open access: yes, 2008
With the introduction of alternative housing systems for laying hens in the EU, recent research has focussed on the bacterial contamination of table eggs, e.g. eggshell and egg content contamination.

Plant Growth‐Promoting Rhizobacteria Isolated From Natural Habitats Promote the Growth of Elymus sibiricus and Enhance Its Resistance to Abiotic Stress

open access: yesPlant-Environment Interactions, Volume 6, Issue 6, December 2025.
Two novel PGPR strains, Bacillus mycoides GN‐1 and Bacillus sp. MQ‐5, which were isolated from soils on the Qinghai‐Tibet Plateau, were found to enhance the growth of Elymus sibiricus through the synthesis of indole‐3‐acetic acid (IAA) and the production of siderophores.
