Soil microorganisms utilize extracellular DNA (eDNA)-based biofilms as a defense against xenobiotics. However, the specific effects and transfer pathways of eDNA under persistent agrochemical exposure remain unclear. This study examined dynamics carbofuran-hydrolase gene pchA from Pseudomonas stutzeri PS21. During biofilm formation, was released eDNA, leading to an enrichment beneficial such Acidobacteria Elusimicrobia, which enhanced organic compound metabolism improved soil microbiome resilience. An increase in pchA-associated mobile genetic elements colocalization with other bacterial species indicated potential horizontal (HGT) carbofuran exposure. Additionally, triggered cAMP-dependent apoptotic pathway, 59.6% copy number, suggested that cAMP played role initiating HGT. In conclusion, cAMP-mediated interspecific could enhance microbial coadaptation contamination, thereby strengthening collective stress.

Abstract Industrialization and urbanization have significantly escalated the discharge of heavy metals into aquatic environments, posing serious ecological public health risks. This study explores global research landscape bacterial biosorption for metal removal, emphasizing advancements in methodologies technologies that redefined this field. A bibliometric analysis 298 publications (1987–2024) was conducted to identify key trends, collaboration networks, innovations. Notable include integration nanotechnology, which has enhanced adsorption efficiency selectivity specific metals, genetic engineering approaches optimize strains higher capacity. Furthermore, these developments transformed traditional remediation strategies by providing cost-effective, sustainable, scalable solutions industries such as textiles, mining, energy production. underscores practical relevance wastewater treatment, achieving removal efficiencies exceeding 99% some cases, demonstrated Aspergillus versicolor Shewanella oneidensis MR-1. By bridging scientific innovation with environmental sustainability, highlights a pivotal green technology, offering actionable insights industrial applications sustainability goals.
