Summary: Due to the extensive production and use of diesel, pollution caused by complex hydrocarbon mixtures is a major concern worldwide. This study investigated the presence of diesel-degrading bacteria in different freshwater sediments of the Danube Delta. Ten bacterial strains capable of growing in a minimal medium with diesel as the sole carbon source were isolated and characterized. These strains belong to four genera and seven species and have the potential for bioremediation of diesel-polluted environments.

Summary: The study tested the survival and biodegradation capabilities of 15 bacterial isolates in a diesel environment, and found that only two bacteria could effectively consume diesel hydrocarbons, with one capable of degrading heavier C24 and C26 compounds. The research demonstrated that the isolated bacterial strain Bacillus sp. E-5 has bioremediation potential and can be used as an alternative method for cleaning contaminated petroleum hydrocarbon field sites.

Summary: The study found higher microbial activity in biodiesel-contaminated soils compared to diesel-contaminated ones, while contaminated soils had lower bacterial richness and diversity. Actinobacteria were predominant in control samples, whereas Proteobacteria were predominantly observed in diesel and biodiesel contaminated soils. Genus-level analysis showed Rhodococcus and Pseudomonas spp. were highly selected in diesel and biodiesel amendments, respectively. Predicted functional profiles based on hydrocarbon-degrading enzymes showed significant differences between contaminated soils, with Burkholderiaceae, Novosphingobium, Anaeromyxobacter, Pseudomonas and Rhodococcus identified as main bacterial taxa contributing to these enzymes.

Summary: This study reports the isolation and characterization of two fungal strains with the potential to degrade pure polypropylene (PP). The selected fungi, Coniochaeta hoffmannii and Pleurostoma richardsiae, showed activity against pure PP and exhibited distinct differences in the bonds targeted during degradation. Whole genome and transcriptome sequencing revealed potential adaptations of these strains to hydrocarbon-rich environments. This research provides a foundation for further investigation of PP degrading activity in C. hoffmannii and P. richardsiae.

Summary: This study evaluates the role of extraradical mycelium of arbuscular mycorrhizal fungi in Pb transport and the protective effect against Pb provided by the mycoremediated dry olive residue (MDOR). Wheat roots accumulate larger amounts of Pb, with increases in extraradical mycelium and glomalin related protein content when MDOR is added to Pb-contaminated soil samples.

Summary: The application of biochar made from olive residue can enhance the functionality and abundance of microbial communities in metal-contaminated soils. Biochar amendment increases microbial abundances and has different effects on enzyme activities depending on the pyrolysis temperature and application dose. Inoculation with arbuscular mycorrhizal fungi promotes the growth of AMF community and results in increased soil glomalin content and AMF root colonization rates.

Summary: The paper proposes a novel way to obtain an effective multi-domain coculture that can degrade multiple pharmaceutical compounds simultaneously. By investigating seven microorganisms isolated from sewage sludge and using the BSocial analysis web tool, artificial cocultures were established and ranked based on their degradation performance. The minimal active microbial consortia consisting of Penicillium spp., Cladosporium cladosporoides, and coexisting bacteria showed the highest performance (>80% degradation) in transforming the pharmaceutical active compounds to derivative molecules with low ecotoxicity.

Summary: Symbiotic associations with different arbuscular mycorrhizal fungi (AMF), namely Rhizoglomus custos (Custos), Rhizoglomus sp. (Aznalcollar), and Rhizophagus irregularis (Intraradices), were studied to investigate their effectiveness in reducing heavy metal stress in wheat grown in contaminated soils. The indigenous Aznalcollar fungus showed higher levels of metal accumulation, while the non-indigenous Custos and Intraradices fungi exhibited depletion of some metals. Both Custos and Intraradices fungi demonstrated greater bioaccumulation capacity in the less-contaminated soil. The enzymatic activity and antioxidant systems of the plants increased in all AMF treatments, indicating improved plant protection in HM-contaminated environments.

Summary: Plastics and microplastics are widely present and accumulating in the environment, leading to increasing public attention. In addition to packaging plastics, materials from industries such as electronics, space and aviation are also accumulating, but receiving less attention. The production of degradable and biodegradable plastics is seen as a way to reduce environmental impacts, but enhancing the non-degradability of functional polymers is also a feasible option. Microbial colonization and deterioration pose significant challenges to these materials.

Summary: This study evaluated the keratinolytic activity of 37 strains of Trichophyton ajelloi and found that pigmented strains isolated from loamy soil were more efficient in degrading native feather keratin, while non-pigmented strains isolated from chernozem showed better abilities. The keratinolytic activity increased over time, as evidenced by the increase in extracellular keratinase activity and release of soluble proteins and peptides. Protease activity peaked in the first 7 days and again on day 28 of culture. The release of ammonium and sulfate ions, associated with an increase in pH, reached its maximum on day 21. Three pigment-producing strains were among the most active in releasing large amounts of ammonium and sulfate ions. The biodegradation of feather waste by Trichophyton ajelloi strains can be used to produce fertilizers suitable for plants with high sulfur requirements.

Summary: This study investigated the degradation of heat-treated wood by brown rot fungi and found that the decay increased the hygroscopicity of wood in the decaying state. Furthermore, it was observed that heat-treated samples were more susceptible to fungal decay compared to untreated samples, which may be related to the increase in moisture content.
