This paper presents a tightly coupled experimental and kinetic approach for efficient remediation of oil spill from contaminated marine intertidal zone surface through a methodical strategy that deals with biosurfactant mediated washing strategy. The study deals with production, optimization and characterization of lipopeptide biosurfactant from Bacillus subtilis T1 and its application in remediation of oil contaminants from mimic model system of various marine intertidal zone i.e. woodland-Group1, saltmarsh-Group2, mangrove-Group3 and mudflats-Group4. Results demonstrates enhanced washing performance with oil desorption rate of 35 % in Group 4, 17.22 %, 15.6 % and 11 % in Group 3, 2 and 1 along with bio surfactant recovery rate of 41 %, 48.7 %, 51.71 % and 50.3 % respectively. Further, the washing strategy was efficient in soil detoxification with highest rate in Group 4. The kinetic validation depicts good match among experimental data and Lagergren pseudo second order data.
本文提出了一种紧密结合的实验和动力学方法，通过一种系统的策略，有效地修复受污染的海洋潮间带表面的溢油，该策略涉及生物表面活性剂介导的洗涤策略。该研究涉及从枯草芽孢杆菌 T1 生产、优化和表征脂肽生物表面活性剂，并将其应用于修复模拟模型系统中的各种海洋潮间带的油污染物，即林地组 1、盐沼组 2、红树林组 3 和泥滩组 4。结果表明，在第 4 组中，油解吸率提高了 35%，在第 3 组、第 2 组和第 1 组中，油解吸率分别提高了 17.22%、15.6%和 11%，同时生物表面活性剂回收率分别提高了 41%、48.7%、51.71%和 50.3%。此外，该洗涤策略在土壤解毒方面非常有效，第 4 组的效率最高。动力学验证表明，实验数据与 Lagergren 拟二级数据吻合较好。
