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 <em>Schizoporella errata<\/em>, <em>Botrylloides violaceu<\/em>s, <em>Callyspongia diffusa, Halichondria panicea<\/em> and <em>Acanthella cavernosa<\/em> showed significant resistance to Escherichia coli settlement and biofilm formation within the first 12 h (OD600 &lt; 0.1). Following gas chromatographic and mass spectrometry (GC-MS) analysis, antimicrobial compounds such as dodecanoic acid, methyl palmitate, \u03b2-caryophyllene, hentriacontane geraniol and \u03b2-asarone were detected in these species.<\/p>\n\n\n<figure class=\"wp-block-post-featured-image\"><img loading=\"lazy\" width=\"859\" height=\"764\" src=\"https:\/\/science.sjp.ac.lk\/zoo\/wp-content\/uploads\/sites\/20\/2026\/03\/Prof-Kamal-2-3.jpg\" class=\"attachment-post-thumbnail size-post-thumbnail wp-post-image\" alt=\"\" decoding=\"async\" style=\"object-fit:cover;\" srcset=\"https:\/\/science.sjp.ac.lk\/zoo\/wp-content\/uploads\/sites\/20\/2026\/03\/Prof-Kamal-2-3.jpg 859w, https:\/\/science.sjp.ac.lk\/zoo\/wp-content\/uploads\/sites\/20\/2026\/03\/Prof-Kamal-2-3-300x267.jpg 300w, https:\/\/science.sjp.ac.lk\/zoo\/wp-content\/uploads\/sites\/20\/2026\/03\/Prof-Kamal-2-3-40x36.jpg 40w, https:\/\/science.sjp.ac.lk\/zoo\/wp-content\/uploads\/sites\/20\/2026\/03\/Prof-Kamal-2-3-768x683.jpg 768w\" sizes=\"(max-width: 859px) 100vw, 859px\" data-id=\"4789\" \/><\/figure>","protected":false},"excerpt":{"rendered":"<p>Published in: Regional Studies in Marine Science DOI: https:\/\/doi.org\/10.1016\/j.rsma.2025.104120 There is limited knowledge of the physical and chemical properties of the biofouling organisms in the coastal waters surrounding Sri Lanka. &hellip; <a href=\"https:\/\/science.sjp.ac.lk\/zoo\/2026\/03\/28\/chemical-composition-and-biofilm-inhibition-potential-of-selected-biofouling-organisms-from-coastal-waters-of-western-sri-lanka\/\" class=\"more-link\">Continue reading <span class=\"screen-reader-text\">Chemical composition and biofilm inhibition potential of selected biofouling organisms from coastal waters of western Sri Lanka<\/span><\/a><\/p>\n","protected":false},"author":136,"featured_media":4789,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_ti_tpc_template_sync":false,"_ti_tpc_template_id":"","footnotes":""},"categories":[7],"tags":[],"_links":{"self":[{"href":"https:\/\/science.sjp.ac.lk\/zoo\/wp-json\/wp\/v2\/posts\/4783"}],"collection":[{"href":"https:\/\/science.sjp.ac.lk\/zoo\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/science.sjp.ac.lk\/zoo\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/science.sjp.ac.lk\/zoo\/wp-json\/wp\/v2\/users\/136"}],"replies":[{"embeddable":true,"href":"https:\/\/science.sjp.ac.lk\/zoo\/wp-json\/wp\/v2\/comments?post=4783"}],"version-history":[{"count":2,"href":"https:\/\/science.sjp.ac.lk\/zoo\/wp-json\/wp\/v2\/posts\/4783\/revisions"}],"predecessor-version":[{"id":4802,"href":"https:\/\/science.sjp.ac.lk\/zoo\/wp-json\/wp\/v2\/posts\/4783\/revisions\/4802"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/science.sjp.ac.lk\/zoo\/wp-json\/wp\/v2\/media\/4789"}],"wp:attachment":[{"href":"https:\/\/science.sjp.ac.lk\/zoo\/wp-json\/wp\/v2\/media?parent=4783"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/science.sjp.ac.lk\/zoo\/wp-json\/wp\/v2\/categories?post=4783"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/science.sjp.ac.lk\/zoo\/wp-json\/wp\/v2\/tags?post=4783"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
