This study investigates the impact of heavy metal pollution on soil bacterial and fungal communities in the Baddi-Barotiwala-Nalagarh (BBN) Industrial Corridor, Himachal Pradesh, India. Soil samples were analyzed for physicochemical properties and heavy metal content, i.e., cadmium (Cd), iron (Fe), copper (Cu), arsenic (As), lead (Pb), chromium (Cr), zinc (Zn), and manganese (Mn), followed by the isolation and characterization of culturable bacterial and fungal communities. Microbial profiling indicated significant variations in community composition, diversity, and abundance across industrial sites. Firmicutes (Bacillota) and Proteobacteria emerged as dominant bacterial phyla, while the fungal communities were predominantly composed of Ascomycota. Although overall microbial richness and diversity declined with increasing heavy metal concentrations, several isolates exhibited key plant growth-promoting (PGP) traits, including phosphate solubilization, siderophore production, indole-3-acetic acid (IAA) synthesis, ammonia production, and nitrate reduction. Pearson correlation analysis demonstrated a relation between microbial community structure and multiple environmental variables, including heavy metals and key soil physicochemical properties. The findings highlight the dual role of soil microbes as indicators of environmental stress and as potential agents for microbe-assisted bioremediation.","PeriodicalId":14235,"journal":{"name":"International Journal of Phytoremediation","volume":" ","pages":"1-13"},"PeriodicalIF":3.1,"publicationDate":"2025-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145336858","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Surface soils (0-15 cm) were collected, filled into 8-kg pots, and planted at a density of 50 plants m-2 (35 B. juncea, 15 U. dioica), followed by 60 days of wastewater irrigation. Metal accumulation exhibited a root > stem > leaf distribution in both species, with B. juncea recording higher concentrations (Cd: 634.36 mg/kg; Pb: 563.54 mg/kg; Ni: 445.68 mg/kg) compared to U. dioica (Cd: 317.18 mg/kg; Pb: 305.92 mg/kg; Ni: 222.84 mg/kg).

Phytoremediation indices (bioconcentration factor (BCF), translocation factor (TF), and efficiency) confirmed Pb as the most effectively removed element, with B. juncea extracting ∼68.5% of soil Pb in one cycle.

Morphological, anatomical, and histochemical analyses were performed, along with gas chromatography and fluorescence microscopy, to assess the plant's potential for petroleum uptake. Results indicated that individuals from the contaminated site developed longer leaves, produced phenolic compounds, and formed aerenchyma as adaptive responses to environmental stress, while leaf count remained unchanged, and no evidence of xenobiotic absorption was found. This lack of uptake likely explains the absence of significant growth inhibition or severe anatomical damage. These findings suggest that T. domingensis has successfully adapted to the contaminated environment, possibly using petroleum degradation by-products to enhance its growth.

The impact of Ag ions was evaluated by measuring (i) the stress markers, viz. MDA and proline, and (ii) the uptake of silver content in treated plants using an atomic absorption spectrophotometer (AAS). Exogenously generated Ag nanoparticles (AgNPs) were characterized through UV-Vis spectroscopy, Transmission Electron Microscopy (TEM), Selected Area Electron Diffraction (SAED), Energy Dispersive X-ray (EDX), and Fourier Transform-Infra Red (FTIR) spectroscopy investigations characterized exogenously generated AgNPs.Results: The study examined the effects of silver ions (Ag+). Results indicated that treatment with 1 mM AgNO3 for 36 h led to a 5-fold reduction in MDA levels and a 3-fold decrease in Proline. Additionally, a color change in the AgNO3 solutions, from a clear, colorless solution to a brown, colloidal suspension. The UV-Vis absorption spectra of these colloidal solutions exhibited a plasmon resonance band at 430-480 nm. A peak at this position confirms the presence of AgNPs. TEM coupled with SAED revealed the presence of crystalline spherical AgNPs in the size range of 5-50 nm in the brown colloidal solution.

Outstanding biosorption efficiency and underdeveloped mechanism of complexation with metal and other water contaminants by the living plant and its biomass might be quite fascinating. It can reveal broad scopes of research to extract many outstanding end-use outcomes in water treatment. The study is classified into three major sections, viz. global arsenic impact, existing tools to combat it - their pros and cons - and prospects of E. crassipes in its remediation. Performances in their different forms (living and nonliving) have been critically reviewed. Alongside, arsenic chemistry and distribution are briefly covered and a few proposed mechanisms of its remediation by the plant also have been assessed.

Unlike organic pollutants, these metals resist biodegradation and accumulate in soils, water, and living organisms, creating severe ecological and health risks. Conventional remediation techniques are expensive, energy-intensive, and produce secondary waste, driving the need for sustainable alternatives. Bioremediation, particularly phytoremediation and mycoremediation, has emerged as an eco-friendly and cost-effective strategy. Recent studies highlight the central role of proteins and peptides in these processes. In plants, metal transporters, metallothioneins, phytochelatins, and redox enzymes regulate the uptake, detoxification, and sequestration of metals, while fungi rely on extracellular enzymes, redox-active metabolites, and cell wall proteins for biosorption and transformation. Advances in protein engineering and synthetic biology now enhance the ability of plants and fungi to target and detoxify metals with greater efficiency. The novelty of this review emphasizes the mechanistic contributions of proteins and peptides to bioadsorption, bioaccumulation, and biotransformation, while addressing current challenges related to scalability, environmental variability, and regulatory acceptance. By integrating synthetic biology, nanobiotechnology, and omics-driven protein discovery, we propose design-based frameworks for next-generation remediation that could transform heavy metal cleanup into predictable, programmable, and field-ready technologies.","PeriodicalId":14235,"journal":{"name":"International Journal of Phytoremediation","volume":" ","pages":"1-17"},"PeriodicalIF":3.1,"publicationDate":"2025-10-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145292206","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
