Summary: This study combined biochar and urea to enhance the phytoremediation of petroleum-contaminated soil. The results showed that the degradation rate of petroleum hydrocarbons increased significantly when biochar, urea, and ryegrass were co-applied. Soil physicochemical properties and microbial activities were also influenced by the treatments. Furthermore, the application of biochar and urea activated the metabolism pathway of petroleum hydrocarbons in root soil. Overall, this study demonstrated the potential of biochar and urea for improving the ecofriendly and cost-effective in-situ bioremediation technology for petroleum-contaminated soils.

Summary: Soil degradation through salinization and pollution by toxic compounds is a significant threat to coastal wetlands. Bioremediation using plants, biochar, and microbes is a cost-effective option for remediation. Biochar enhances plant/microbe growth and can effectively remediate petroleum hydrocarbons (PHCs) in salinized soils. Plant-microbe interactions mediated rhizodegradation and microbial respiration is more active in biochar amendments. The use of biochar, plants, and microbes is recommended for sustainable and practical remediation of PHCs and salinization.

Summary: A greenhouse experiment was conducted to evaluate the effect of phytoremediation and biochar application on hydrocarbon degradation in crude oil-contaminated soils. The experiment involved four levels of biochar application (0, 5, 10, and 15 t/ha) and the presence or absence of Vigna unguiculata (cowpea; +C, -C), replicated three times in a 4 x 2 x 3 factorial design. The results showed that the highest degradation efficiency of 69.2% (7033 mg/kg) was achieved in contaminated soils amended with 15 t/ha biochar after 60 days of incubation. Significant interactions were observed between biochar x plant and biochar x days. Biochar also enhanced plant growth in contaminated soils.

Summary: The study investigated the impact of soil amendments (biochar and compost) on phytoremediation of TPHs by plants from Poaceae and Fabaceae families. Results showed that biochar and compost improved plant growth and TPH removal, with ryegrass and white clover exhibiting the highest removal rates. Different plant species responded differently to soil amendments in terms of TPH degradation.

Summary: The study found that extracts of Spartina anglica have antioxidant, anti-obesity, and whitening properties. Particularly, the ethyl acetate fraction derived from the aerial parts showed strong radical-scavenging and pancreatic lipase inhibitory activities.

Summary: Spartina anglica is an invasive species that can cause extinction of native species. Traditional field surveys are expensive, but using UAV remote sensing and deep learning techniques can automatically map the occurrence of invasive species. We implemented DL semantic segmentation on UAV imagery of Spartina-invaded habitats, and found that the U-Net architecture with Inception-v3 backbone performed the best. Data augmentation and pseudo-labelling techniques also improved model performance.

Summary: The invasion of Spartina anglica significantly altered the characteristics of tidal salt marsh soil archaeal community, mainly in the surface layer, with indirect effects on deeper soil layers. Shifts in archaeal phyla such as Asgardaeota and Diapherotrites indicated a transformation from marine to terrestrial archaeal communities. Changes in dissolved organic carbon and salinity were the substantial regulating factors for the invasion impacts propagation to deeper soil layers.

Summary: The combination of rhamnolipids and ABA-metabolizing bacterium Rhodococcus qingshengii has shown great potential in enhancing the phytoremediation efficiency of hyperaccumulating plants in heavy metal-contaminated soils. This combination improves the accumulation of heavy metals in plants, increases biomass, and activates available forms of heavy metals in the soil. The contribution of Rhodococcus qingshengii in promoting the extraction of heavy metals from the soil is greater than that of rhamnolipids.

Summary: Vegetation changes in saltmarsh habitat can affect fish assemblages and abundance. This study found that the introduced tall grass, Spartina anglica, has a negative impact on fish, while native saltmarshes are more beneficial for fish reproduction and growth.

Summary: In order to improve the bioremediation efficiency of petroleum-contaminated soil, five test groups were selected in this study. The results showed that there was no significant difference in the removal efficiency of TPH between native bacteria and A.V. bacteria group. However, the cultivation of Vetiveria zizanioides L. could significantly increase the removal efficiency of TPH.

Summary: With the development of industries and excessive use of petroleum compounds, petroleum pollution has become a serious threat to the environment. This study aimed to investigate the effect of phytoremediation and bioaugmentation on the biological activities of soil contaminated by petroleum. The results showed that sorghum and bermudagrass were more tolerant to petroleum toxicity compared to barley, and the bacteria had a greater positive effect on the dry weight of polluted soil compared to non-polluted soil. Plants had a higher ability to degrade total petroleum hydrocarbon (TPH), while bacteria were better at degrading polyaromatic hydrocarbons (PAHs).
