摘要

人们对斯里兰卡周围沿海水域生物污染生物的物理和化学特性了解有限。本研究通过次生代谢物对生物膜形成的影响，研究了9种海洋大型污染生物的化学多样性和环境恢复力。抗沉降试验结果表明，裂口菌、紫葡萄球菌、白花粘绵菌、海绵体棘菌对大肠杆菌沉降和生物膜形成在前12 h内表现出显著的抗性(OD600 <；0.1)。通过气相色谱和质谱（GC-MS）分析，在这些物种中检测到十二烷酸、棕榈酸甲酯、β-石竹烯、hentriacontane香叶醇和β-细辛酮等抗菌化合物。

Chemical composition and biofilm inhibition potential of selected biofouling organisms from coastal waters of western Sri Lanka

There is limited knowledge of the physical and chemical properties of the biofouling organisms in the coastal waters surrounding Sri Lanka. This study investigates the chemical diversity and environmental resilience of nine species of marine macrofouling organisms through secondary metabolite-induced effects on biofilm formation. The anti-settlement assay revealed that Schizoporella errata, Botrylloides violaceus, Callyspongia diffusa, Halichondria panicea and Acanthella cavernosa showed significant resistance to Escherichia coli settlement and biofilm formation within the first 12 h (OD₆₀₀ < 0.1). Following gas chromatographic and mass spectrometry (GC-MS) analysis, antimicrobial compounds such as dodecanoic acid, methyl palmitate, β-caryophyllene, hentriacontane geraniol and β-asarone were detected in these species.
