Mutans of Pseudomonas testosteroni were isolated for their inability to grow on m-hydroxybenzoate as sole carbon source. These mutants hydroxylated m-hydroxybenzoate for form 2,3-dihydroxybenzoate in high yeilds. The bioconversion described in this report represents the first reported example of 3-hydroxybenzoate 2-hydroxylase activity.

Xenobiotic aromatic compounds are the raw materials of necessities in modern life, such as plastics, pesticides, and antibiotics. To meet the global requirements, their production and consumption have continually increased, and thus, the vast amount of waste generated results in prominent environmental pollution. Fortunately, some microorganisms (e.

The abundant production of plastic materials, coupled with their recalcitrant nature, makes plastic waste a major challenge as a pollutant. Polyethylene terephthalate (PET) is a polyester formed by polycondensation of terephthalic acid (TPA) and ethylene glycol (EG). This plastic polymer can be completely depolymerized to its monomers using microbial enzymes.

Article Synopsis
  • Microbial evolution can occur in positive inter-species interactions, leading to different evolutionary outcomes.
  • In a study, four microbe species were evolved in both monocultures and communities to see how they interacted under the presence of a toxic pollutant.
  • After 44 weeks, some species evolved to rely on each other less and showed signs of resource specialization, contradicting the Black Queen Hypothesis which suggested they would develop stronger mutualistic relationships.
  • Ultimately, the co-evolved community was less effective at degrading the pollutant compared to their ancestors, indicating that collaboration among species can lead to weaker interactions and hinder adaptation.

Enhanced biodegradation of high-density polyethylene microplastics: Study of bacterial efficiency and process parameters.

J Hazard Mater

December 2024

Department of Chemical and Environmental Engineering, University of Oviedo, C/ Julián Clavería s/n, Oviedo 33006, Spain.

As global microplastic (MP) pollution intensifies, sustainable and effective remediation methods are gaining interest due to the growing environmental and health implications. Microorganisms are demonstrating remarkable capabilities to degrade these polymers, offering a promising solution for reducing MP contamination. The aim of this study was to utilize bacteria for the degradation of high-density polyethylene (HDPE) MPs, specifically Comamonas testosteroni NCIMB 8955, Bacillus firmus NCTC 10335 and Paenibacillus macquariensis NCTC 10419.

This study presents the first case in Poland of isolation and molecular identification of the Spironucleus vortens parasite from the digestive tract of diseased ornamental fish belonging to the species discus fish (Symphysodon discus Heckel, 1840). Recently, an increasing percentage of fish submitted for testing to the Department of Biology and Fish Diseases, have been observed that show typical symptoms of hole-in-the-head disease, therefore it is important to have accurate information about this disease. In preparation of this work, two fish were studied.
