Summary: This study evaluated the effects of planting a native perennial grass with a consortium of diazotrophic microbial endophytes and municipal waste compost on plant growth and metal stabilization in tailings from a polymetallic mineral deposit. The results showed that the most effective treatment for improving soil acidity, nitrogen content, and organic carbon and biomass yields of grass was the simultaneous use of dolomite, compost, and endophyte seed coating. Compost reduced the concentrations of contaminant metals in the shoots and roots of the grass, while the endophytes increased the yields of certain metals in the leaves and mobilized others from the tailings.

Summary: Soil contamination by heavy metals is a serious environmental issue. Phytoremediation, using hyperaccumulating ornamental plants, is a cost-effective and eco-friendly method for heavy metal removal. This study highlights the metal accumulation potential, removal mechanism, and growth response of hyperaccumulators, and suggests the use of genetically modified plants for improved efficiency in phytoremediation. Factors such as soil characteristics, metal type, plant species, and bio-inoculants play a crucial role in the success of phytoremediation.

Summary: The release of organic compounds in the aquatic environment is a serious hazard due to their toxic, hydrophobic, and persistent nature, making the removal of these contaminants a major topic in environmental science research. Phytoremediation, using plants to clean up pollutants, is a crucial process, with endophytic bacteria playing a key role in contaminant removal. Understanding the mechanisms behind bacterial-plant interactions is essential for various biotechnological applications.

Summary: This study used PS-Eu particles to track the uptake and transport of micro-and nanoplastics in aquatic plants and investigated the potential of different aquatic plants for trapping and removing plastics in water environment. The results showed that PS-Eu mainly accumulated in the intercellular space and were transported from roots to leaves via the apoplastic path and vascular bundle. Mass spectrum analysis demonstrated that up to 6250 jig/g nanoplastics were trapped in aquatic plants, mainly in roots, with a bioconcentration factor of 306.5. Floating plants like E. crassipes showed promising capability for immobilizing and removing fine plastics from the water environment.

Summary: Decorative ornamental plants such as Impatiens balsamina, Mirabilis jalapa, and Tagetes erecta have shown strong tolerance to Tin (Sn) contamination, with Impatiens balsamina and Tagetes erecta exhibiting high accumulation capacity, while Mirabilis jalapa has high translocation ability. These plants have the potential to be used as phytoremediators for Sn mining tailings or contaminated soil, due to their adaptation to high concentrations of various heavy metals.

Summary: Arsenic is a common and toxic inorganic pollutant, and phytoremediation using plants such as Cannabis sativa, Brassica juncea, and Zea mays has shown promise in removing arsenic from contaminated soil. This study aimed to identify the optimal experimental conditions for a phytoremediation plan using these plants in a contaminated area in Sicily, Italy. Chelating agents and arsenic-tolerant bacteria were used to enhance arsenic mobility and plant growth, resulting in significant improvement in biomass production and phytoextraction. The study confirmed that all three plants were able to significantly increase arsenic absorption after the treatment.

Summary: Endophytes have shown to enhance the physiological status of plants under metallic stress, promote the growth of roots and shoots, and increase metal uptake in the biomass of hyperaccumulating plants. Endophyte-assisted phytoremediation is a promising technology for remediating polluted or naturally metal-rich soils.

Summary: Phytoremediation is a green and cost-effective technology for removing heavy metals from soil and water resources. Factors such as heavy metal type and concentration, phytoremediation method, climatic conditions, plant species, biomass production, plant sensitivity, and signaling pathways efficiency are crucial for the effectiveness of phytoremediation. Ornamental, medicinal, and aromatic plants are promising for phytoremediation due to their fast growth and high biomass production. Genetic technologies like CRISPR/Cas9 genome editing can enhance phytoremediation properties. This review summarizes the current knowledge on plant tolerance mechanisms to heavy metals and the use of genetically engineered plants for phytoremediation. Risk assessments and regulatory approaches for transgenic plants are also discussed.

Summary: Arbuscular mycorrhizal fungi (AMF) play a crucial role in promoting plant growth and productivity, particularly under poor soil fertility. The balance between zinc (Zn) and phosphorus (P) application is important for maximizing crop yield. The study found that AMF colonization increases under deficient Zn and P conditions. Higher soil Zn levels inhibit germination and plant growth, but AMF inoculation greatly improves these factors. The optimal treatment for wheat growth in Zn-deficient conditions is the application of low Zn levels (30 or 60 mg kg(-1)) with 21 mg kg(-1) P, in combination with AMF inoculation.

Summary: Heavy metals (HMs) are non-biodegradable and can be transferred from environmental matrices to plants through phytoremediation. Phytoremediation of HMs has advantages such as biophilia and carbon neutrality compared to other remediation methods. Studies also suggest that phytoremediation is more sustainable based on life cycle assessment. However, proper management of HMs contaminated biomass after phytoremediation is a challenge, as it can reintroduce HMs into the environment. This review discusses a sustainable phytoremediation strategy using life cycle assessment and various biomass management options.

Summary: This research identified the potential of biosurfactant-producing fungal strains belonging to Aspergillus, Penicillium, and Candida genera for enhancing the hydrocarbon degradation process. The highest biodegradation was observed in Aspergillus niger FA5, followed by Penicillium chrysogenum FP4, Aspergillus terreus FP6, and Candida sp. FG2. The results indicate that fungi capable of producing biosurfactants and effectively reducing surface tension show significant improvements in the rate of hydrocarbon degradation.

Summary: Heavy metal contamination affects plant growth and productivity by causing damage to various levels of plant organization. This study investigated the uptake and distribution of cadmium (Cd) and copper (Cu) in Solanum lycopersicum L. and examined the antioxidant enzyme activity and tolerance capacity. The results showed significant decreases in biomass and growth parameters in response to Cd and Cu stress, indicating that S. lycopersicum is not tolerant or an accumulator of these metals. The use of chelators or soil conditioners may be necessary to mitigate metal toxicity.

Summary: In this study, a novel type of biochar called electromagnetic biochar was prepared using raw biochar derived from parthenium weed through electrolysis and chemical co-precipitation with Fe2+. The resulting electromagnetic biochar had an increased surface area, magnetism, and modified surface chemistry due to the formation of iron oxide minerals (magnetite and hematite). It exhibited a 73% higher capacity for adsorbing Cd from industrial wastewater than raw biochar, and remained highly stable in strongly acidic and alkaline aquatic environments, making it a promising tool for Cd removal.
