Summary: This study compared the effects of Rhodococcus bioaugmentation and biostimulation on the degradation of DBT and bacterial community interaction in petroleum-contaminated soils. The results showed that Rhodococcus bioaugmentation had the highest DBT degradation efficiency, with the majority of degradation occurring within the first 30 days. The composition of bacteria differed significantly among the different treatments, and Bacillus and Paenibacillus were identified as the dominant genera involved in DBT degradation.

Summary: This study evaluated the impact of legacy petroleum hydrocarbons on the indigenous soil microbial community in the Kimberley region of Western Australia. The results showed that the presence of petroleum hydrocarbons decreased microbial diversity, altered microbial community structure, and increased the abundance of putative hydrocarbon degraders. The study highlights the long-term effects of hydrocarbon spills on soil microbial communities in remote, infertile monsoonal soils, while also indicating the potential for natural attenuation in these environments.

Summary: This study investigated the application of bioremediation with sinusoidal alternating current electric fields for soil remediation, showing that the AC+BIO system was more efficient in removing petroleum hydrocarbons compared to BIO or AC alone. The study also found that the appropriate AC voltage gradient had an impact on microbial communities and TPH degradation efficiency. Further research and practical applications are warranted based on the insights provided by this study.

Summary: Petroleum hydrocarbons, which are organic molecules consisting of carbon and hydrogen, are pervasive environmental toxins found in crude oil. They can have negative consequences on the ecosystem, including soil, water, and air pollution, as well as agricultural land. The effects of petroleum hydrocarbons on agricultural land are influenced by factors such as the specific hydrocarbon, soil properties, and climatic circumstances. These hydrocarbons can lead to soil compaction, decreased infiltration, and higher runoff, affecting agricultural land production. They can also impair soil aeration, change soil pH and nutrient availability, and affect microbial activity and composition, reducing soil fertility and production. Additionally, certain crops are more susceptible to hydrocarbon contamination than others. Physicochemical strategies have been used to mitigate petroleum hydrocarbon contamination, but they come with drawbacks. Biological remediation methods, utilizing microorganisms or plants, offer alternatives to reduce the effects of contamination.

Summary: Polycyclic aromatic hydrocarbon (PAH) pollution is a global concern due to its toxicity and negative impact on the environment and ecosystem. Bioremediation using microorganisms such as bacteria and fungi is becoming an effective and eco-friendly technique to remove PAHs from the environment. Nanoparticles can also be used in bioremediation, reducing toxic effects and overall time and costs. This article provides a summary of the application of nanomaterials, bacteria, and fungi in PAH remediation and discusses the structure, properties, sources, fate, toxicity, and remediation approaches involved.

Summary: Soil microorganisms can decompose petroleum at low concentrations for soil remediation. The study found that heavy soil pollution cases are less studied, and oil pollution leads to changes in microbial community composition. Oil-degrading bacteria became dominant in all soil samples regardless of the level of petroleum pollution.

Summary: In this study, a newly isolated strain, Aeromonas sp. BCP-3, was inoculated into contaminated soils to remove PAHs through slurry bioreactors. The removal efficiency of PAHs was significantly influenced by various factors, including aeration rate, water-soil mass ratio, stirring rate, temperature, and Tween-80 concentration. Under optimal conditions, 96.3 % and 97.2 % of initially spiked fluoranthene and pyrene were successfully removed within 12 days.

Summary: Polycyclic aromatic hydrocarbons (PAHs) in marine sediment pose a significant threat to biological security. The addition of terminal electron acceptor (TEA) has been found to be an effective strategy to enhance bioremediation. This study demonstrated that the utilization of HCO3- and SO42- as TEAs significantly enhanced the biodegradation of PAHs compared to NO3-.

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.
