ABSTRACT Cadmium (Cd)‐contaminated rice paddies have been a primary environmental concern worldwide. Biochar or modified biochar application favors reducing Cd availability in paddy soil, which has demonstrated physical and chemical terms. However, we know little about soil microbial responses after application. In this study, revealed the immobilization effect mechanism of fields by novel phosphorite magnetic (PMCB) from perspective response. The results suggested that PMCB facilitated conversion highly active to less reduced uptake improving physicochemical properties functional bacterial gene abundance. Compared with control, acetic acid extractable reducible contents content brown decreased 7.4%–18.4%, 16.2%–19.9%, 44.0%–47.9%, respectively, residual increased 16.3%–25.8% under treatment. A decrease sqr fccB abundances (downregulated 6.3% 12.4%, respectively) inhibited CdS oxidative dissolution 0.2% Conversely, other treatments stimulated abundant proliferation microbes (e.g., Anaeromyxobacter , Geobacter Thiobacillus ) these genes while suppressing sulfide‐producing abundance (sreA phsA 30.5%–73.4% 3.3%–11.3%, respectively). This result implies Fe(III) mineral reduction oxidation lead limited secondary release Cd. Additionally, aqueous‐phase analysis immobilized mainly coprecipitation PO 4 3− CO 3 2− (34.5%) ion exchange (32.2%), followed surface complexation (18.7%) cation π‐bonding (13.1%).

Microbial Degradation of Soil Organic Pollutants: Mechanisms, Challenges, and Advances in Forest Ecosystem Management

Processes, Год журнала: 2025, Номер 13(3), С. 916 - 916

Опубликована: Март 20, 2025

With industrialization and widespread chemical use, soil organic pollutants have become a major environmental issue. Forest ecosystems, among the most important on Earth, unique potential for controlling remediating pollution. This article explores mechanisms of microbial community degradation pollutants, their adaptability across forest ecological conditions, effects factors efficiency. For example, acidic pH (pH < 5.5) favors PAH degradation, near-neutral (6.0–7.5) enhances pharmaceutical PPCP alkaline conditions > 7.5) facilitate petroleum hydrocarbon, VOC, breakdown. Optimal occurs with humidity levels between 60% 80%, SOM content 2–5%. review analyzes advancements in technologies ecosystem pollution treatment, including genetic engineering, composting, bioaugmentation, bio-stimulation techniques, integration phytoremediation. The also addresses challenges real-world implementation, such as maintaining diversity, managing pollutant complexity, adapting to changes, highlighting future research opportunities. next decade will focus synthetic biology, omics technologies, microbial-electrochemical systems, dynamics, eco-engineering, plant-microbe synergy develop efficient, sustainable bioremediation strategies.

Deciphering Indigenous Bacterial Diversity of Co‐Polluted Sites to Unravel Its Bioremediation Potential: A Metagenomic Approach

Journal of Basic Microbiology, Год журнала: 2024, Номер 64(9)

Опубликована: Июль 11, 2024

ABSTRACT Polluted drains across the globe are affected due to reckless disposal of untreated industrial effluents resulting in significant water pollution affecting microbial community structure/dynamics. To elucidate this, polluted samples were collected from Budha Nala (BN) drain, Tung Dhab (TD) and wastewater treatment plant (WWTP) receiving an inflow organic pollutants as well heavy metals anthropogenic activities. The sample unpolluted pristine soil (PS) was used control, there is no history usage chemicals at this site. bacterial diversity these sequenced using Illumina MiSeq platform by amplifying V3/V4 region 16S rRNA. majority operational taxonomic unit (OTUs) sites belonged phyla Proteobacteria specifically Gammaproteobacteria class, followed Actinobacteria, Bacteriodetes, Chloroflexi, Firmicutes, Planctomycetes, WS6, TM7, whereas site revealed prevalence Acidobacteria, Bacteroidetes, Verrucomicrobia, Nitrospirae. data sets decode unclassified species Proteobacteria, along with some species. study provided a comparative changed structure, their possible functions diverse geographical locations, identifying specific genera bio‐indicators aged drains.

Assessment of the Migration of Polar Compounds from Petroleum-Contaminated Soil Using a Column Leaching Experiment

Journal of the American Society for Mass Spectrometry, Год журнала: 2024, Номер unknown

Опубликована: Сен. 30, 2024

When petroleum leaks into soil, the polar compounds exhibit strong biological toxicity, causing serious damage to soil animals, plants, and microorganisms potentially threatening human health. However, systematic comprehension of migration in petroleum-contaminated remains limited. Herein, we employed elemental analysis, stable carbon isotope high-resolution mass spectrometry techniques study using a column leaching experiment. The results indicate that ability is limited, are primarily concentrated above 40 cm. C/N, C/H, δ
