Polycyclic aromatic hydrocarbons (PAHs), one of the major environmental pollutants, produced from incomplete combustion of materials like coal, oil, gas, wood, and charbroiled meat, that contaminate the air, soil, and water, necessitating urgent remediation. Understanding the metabolic pathways for PAHs degradation is crucial to preventing environmental damage and health issues. Biological methods are gaining increasing interest due to their cost-effectiveness and environmental friendliness. These methods are particularly suitable for remediating PAHs contamination and mitigating associated risks. The paper also outlines the processes for biodegrading PAHs, emphasizing the function of Pseudomonas spp., a kind of bacterium recognized for its capacity to degrade PAHs. To eliminate PAHs from the environment and reduce threats to human health and the environment, Pseudomonas spp. is essential. Understanding the mechanism of PAH breakdown by means of microbes could lead to effective clean-up strategies. The review highlights the enzymatic capabilities, adaptability, and genetic versatility of the genes like nah and phn of Pseudomonas spp., which are involved in PAHs degradation pathways. Scientific evidence supports using Pseudomonas spp. as biocatalysts for PAHs clean-up, offering cost-effective and eco-friendly solutions.
多环芳烃(PAHs)是主要的环境污染物之一,由煤、石油、天然气、木材和烤焦肉类等物质不完全燃烧产生,会污染空气、土壤和水,因此急需进行修复。了解多环芳烃的降解代谢途径对于预防环境破坏和健康问题至关重要。生物方法因其成本效益和环境友好性而越来越受到关注。这些方法特别适合修复多环芳烃污染并降低相关风险。本文还概述了多环芳烃的生物降解过程,强调了假单胞菌属的作用,假单胞菌属是一种以其降解多环芳烃的能力而闻名的细菌。为了从环境中消除多环芳烃并减少对人类健康和环境的威胁,假单胞菌属至关重要。了解微生物分解多环芳烃的机制可能会产生有效的清理策略。该综述强调了假单胞菌属中参与多环芳烃降解途径的基因(如nah和phn)的酶促能力、适应性和遗传多样性。科学证据支持使用假单胞菌属作为多环芳烃清理的生物催化剂,提供具有成本效益和生态友好的解决方案。
