Through the experiment simulated sand columns, the biodegradation characteristics of diesel in sand layers (including fine sand, medium sand and coarse sand) with different depths and moisture contents were studied. The results show that the depth and moisture content of medium are important factors in affecting the efficiency of diesel degradation. In the same medium conditions, the higher moisture content of the medium, the higher biological activity, and biological degradation efficiency of diesel are observed. The nature of medium affects the efficiency of diesel degradation in vadose zone. The finer particles of the medium, the higher ability of diesel degradation is. It is expressed as: fine sand > medium sand > coarse sand. Volatilization and biodegradation are important factors in affecting natural attenuation of diesel in vadose zone.

sp. strain p52, an aerobic dioxin degrader, was capable of utilizing petroleum hydrocarbons as the sole sources of carbon and energy for growth. In the present study, the degradation of the mixture of aliphatic hydrocarbons (hexadecane and tetradecane) and aromatic hydrocarbons (phenanthrene and anthracene) by strain p52 was examined.

The tolerance and degradation characteristics of a marine oil-degrading strain Acinetobacter sp. Y9 were investigated in the presence of diesel oil and simulated radioactive nuclides (Mn, Co, Ni, Sr, Cs) at varying concentrations, as well as exposure to γ-ray radiation (Co-60). The maximum tolerable concentrations for Coand Ni were found to be 5 mg/l and 25 mg/l, respectively, while the tolerable concentrations for Mn, Sr, and Cs exceeded 400 mg/l, 1000 mg/l, and 1000 mg/l, respectively.

Background: Physical exercise is crucial in type 2 diabetes management (T2D), and training in the aquatic environment seems to be a promising alternative due to its physical properties and metabolic, functional, cardiovascular, and neuromuscular benefits. Research on combined training in aquatic and dry-land training environments is scarce, especially in long-term interventions. Thus, this study aims to investigate the effects of combined training in both environments on health outcomes related to the management of T2D patients.

Bioremediation, involving the strategic use of microorganisms, has proven to be a cost-effective alternative for restoring areas impacted by persistent contaminants such as polycyclic aromatic hydrocarbons (PAHs). In this context, the aim of this study was to explore hydrocarbon-degrading microbial consortia by prospecting native species from soils contaminated with blends of diesel and biodiesel (20% biodiesel/80% diesel). After enrichment in a minimal medium containing diesel oil as the sole carbon source and based on 16S rRNA, Calmodulin and β-tubulin gene sequencing, seven fungi and 12 bacteria were identified.
