Summary: Petroleum contamination in marine environments causes serious harm to ecosystems, but bioremediation with immobilized microorganisms shows promise for oil-polluted environments. In this study, Bacillus licheniformis was immobilized in Ca alginate beads for oil biodegradation, with optimized variables leading to higher degradation rates compared to freely suspended cells. The effectiveness of the process variables differed between free and immobilized cell systems, with immobilized cells showing greater potential for crude oil degradation.

Summary: The study focuses on the optimization of crude oil degradation using bacterial and fungal co-culture with cell immobilization techniques. The results show that the co-culture with a bacterial-fungal ratio of 3:1 achieved the highest degradation efficiency and surface tension reduction. Enzyme analysis reveals that catalase played a significant role in the degradation process. The high expression of specific genes correlated with the removal of target compounds. Overall, the application of immobilized bacterial and fungal cells in defined coculture systems proves to be an effective strategy for enhanced biodegradation of petroleum hydrocarbons in aquatic systems.

Summary: The study found that the combination of Eisenia fetida and rhamnolipid JBR-425 with a bacterial consortium resulted in increased degradation levels of polycyclic aromatic hydrocarbons (PAH) from oil-contaminated soil. The bacterial consortium degraded 30-89% of selected PAH after 45 days, with chrysene showing the highest degradation (89%) and benzo(a)pyrene the lowest (30%). The earthworm biomass decreased and mortality rates increased with increasing crude oil concentrations, but a 100% survival rate was observed at 1% crude oil exposure, indicating the potential for bioremediation. The combination of E. fetida with the bacterial consortium showed better degradation of PAH, while rhamnolipid JBR-425 coupled with the consortium resulted in significant degradation as well. Overall, the application of the bacterial consortium in conjunction with E. fetida has great potential for the restoration of contaminated soil and ecosystem sustainability.

Summary: Oil absorbent particles made from surface-modified polypropylene can facilitate the removal of oil from the environment. In this study, it was found that these particles stimulated the growth of biofilms and enriched specific bacterial species. Compared to oil suspension, cultures with these particles degraded more crude oil. Bacterial communities pre-exposed to crude oil had different community structures and degraded more oil.

Summary: Crude oil is a major pollutant that generates contaminated processing waters, harmful to human health and the environment. Different techniques are used for recovery, including the use of bacteria and microalgae. Microalgae can indirectly support the growth of degrading bacteria and directly contribute to the removal of hydrocarbons. The advantages of using microalgae include their ability to remove toxic compounds, release oxygen, and their biomass can be used for biofuel production in a circular economy.

Summary: This study investigated the crude oil degrading capabilities of biosurfactant-producing strains of Pseudomonas aeruginosa and Meyerozyma sp. The biosurfactants produced by these strains showed high emulsification activities in crude oil and stability under various conditions. Gravimetric and GC-MS analyses demonstrated efficient petroleum hydrocarbons degradation by both strains, indicating their potential for bioremediation of hydrocarbons-contaminated sites.

Summary: We enriched bacterial consortia from oilfield samples and found that they have potential for bio-catalytic upgrading of heavy crude oil. Treatment with one bacterial consortium resulted in an increase in saturates fraction, a decrease in aromatics fraction, a reduction in asphaltene content, and an increase in resins. The biotreated oil also showed better recovery of fractions compared to the non-treated oil. The bacterial consortia composition varied with the source and changed over time, with certain bacteria identified as key players in the bioupgrading process.

Summary: Bacteria generate and release extracellular reactive oxygen species (eROS), which significantly contribute to the natural ROS pool and play a crucial role in metabolic interactions of bacteria with their environment. Understanding the behavior of eROS-generating bacteria and its environmental implications is of great importance in the cycling of biogeochemical elements, transformation of organic matter, and regulation of antibiotic resistance genes.

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: The incomplete recycle of residual mulch film (RMF) in recent years has led to an increase in plastic fragments in soil, posing a serious threat to the soil ecological environment. In this study, seven potential plastic-degrading microorganisms were screened and identified from film-mulched vegetable fields. The degradation ability experiments showed that both single strains and mixed strains demonstrated varying levels of degradation of RMF.

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.

Summary: This study investigated the phenomenon of Centimetric circular areas Uncolonized by Microbial Biofilms (CUMBs) on natural and heritage stone surfaces. The analysis revealed a compatibility in distribution and size between CUMBs and lichen thalli, suggesting a lichen origin for some CUMBs. Microscopic analysis also showed similar modifications in marble layers beneath CUMBs and lichens, indicating a possible alteration of stone properties by lichens.
