Abstract

Purpose: This study aims to investigates Pleurotus ostreatus (P. ostreatus) fungi's strain efficacy in degrading oil contaminants, specifically polycyclic aromatic hydrocarbons (PAHs). Materials and Methods: The experiment involved spiking sterilized soil samples with PAHs at concentrations of 200 ppm and 20 ppm for 18 different PAHs. The process, conducted twice for reliability, included allowing P. ostreatus mycelium to proliferate over twenty days. Findings: Gas chromatography-mass spectrometry (GC-MS) analysis revealed a significant 90% degradation rate for certain PAHs. Intriguingly, even in samples without P. ostreatus mycelium, a level of degradation occurred, indicating the participation of indigenous microorganisms or abiotic processes. The study underscores P. ostreatus' potential for PAH degradation and emphasizes the importance of natural remediation techniques for oil-contaminated soils. Implications to Theory, Practice and Policy: Recommendations include exploring factors influencing the degradation process and analyzing the soil's microbial community. Further research is needed to maximize P. ostreatus' environmental remediation applications.

利用胸棘藻对多环芳烃进行生物修复

研究目的：本研究旨在探究褶菌（P. ostreatus）真菌菌株在降解石油污染物，特别是多环芳烃（PAHs）方面的功效。材料与方法：实验涉及在灭菌土壤样本中添加多环芳烃，浓度分别为 200 ppm 和 20 ppm，涉及 18 种不同的多环芳烃。为了保证实验的可靠性，实验过程进行了两次，包括让 P. ostreatus 菌丝体增殖 20 天。研究结果气相色谱-质谱（GC-MS）分析显示，某些多环芳烃的降解率高达 90%。耐人寻味的是，即使在没有奥斯特菌丝体的样本中，也发生了一定程度的降解，这表明有本地微生物或非生物过程的参与。这项研究强调了多环芳烃（PAH）的降解潜力，并强调了石油污染土壤自然修复技术的重要性。对理论、实践和政策的影响：建议包括探索影响降解过程的因素和分析土壤微生物群落。需要进一步开展研究，以最大限度地提高 P. ostreatus 在环境修复方面的应用。
