This study investigated the early stage surface modification of commercially formulated plastics following exposure to the freshwater microalgae\n                    <jats:italic>Scenedesmus dimorphus<\/jats:italic>\n                    and\n                    <jats:italic>Chlorella vulgaris<\/jats:italic>\n                    . Transparent and pigmented polyethylene terephthalate (PET) bottles and agricultural low density polyethylene (LDPE) films were incubated with microalgal cultures for 100\u202fdays under controlled laboratory conditions. Changes in plastic mass and surface properties were evaluated using gravimetric measurements, Fourier-transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM). Weight loss varied among treatment and plastic combinations. Aligned Rank Transform analysis showed significant effects of treatment (\n                    <jats:italic>F<\/jats:italic>\n                    \u202f=\u202f22.54,\n                    <jats:italic>p<\/jats:italic>\n                    \u202f&amp;lt;\u202f0.001), plastic type (\n                    <jats:italic>F<\/jats:italic>\n                    \u202f=\u202f2.50,\n                    <jats:italic>p<\/jats:italic>\n                    \u202f=\u202f0.036), and their interaction (\n                    <jats:italic>F<\/jats:italic>\n                    \u202f=\u202f3.81,\n                    <jats:italic>p<\/jats:italic>\n                    \u202f&amp;lt;\u202f0.001). FTIR analysis indicated changes in carbonyl and aliphatic functional groups, consistent with oxidative surface modification. SEM observations showed surface roughening, cracks, cavities, and localized delamination after microalgal exposure. The magnitude of these changes varied among plastic formulations and microalgal treatments. The results indicate that\n                    <jats:italic>S. dimorphus<\/jats:italic>\n                    and\n                    <jats:italic>C. vulgaris<\/jats:italic>\n                    were associated with detectable physicochemical and morphological changes at the plastic surface during the 100\u202fday incubation period. However, the observed changes represent early stage surface modification and do not demonstrate complete polymer biodegradation or mineralization. The findings highlight the importance of polymer formulation when evaluating microalgae plastic interactions and provide evidence for further investigation of microalgal surface associated plastic alteration.\n                  <\/jats:p>","DOI":"10.3389\/fmicb.2026.1934915","type":"journal-article","created":{"date-parts":[[2026,9,23]],"date-time":"2026-09-23T05:49:41Z","timestamp":1790142581000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Surface bio-erosion and structural alteration of colored and agricultural plastics induced by Scenedesmus dimorphus and Chlorella vulgaris"],"prefix":"10.3389","volume":"17","author":[{"given":"Aysu","family":"Besler","sequence":"first","affiliation":[{"name":"Department of Biology, Faculty of Science, Mu\u011fla S\u0131tk\u0131 Ko\u00e7man University","place":["Mu\u011fla, T\u00fcrkiye"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"\u00d6zlem","family":"G\u00fcr\u00fcnl\u00fc Alma","sequence":"additional","affiliation":[{"name":"Department of Statistics, Faculty of Science, Mu\u011fla S\u0131tk\u0131 Ko\u00e7man University","place":["Mu\u011fla, T\u00fcrkiye"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Murat Can","family":"Sunar","sequence":"additional","affiliation":[{"name":"Faculty of Fisheries, Mu\u011fla S\u0131tk\u0131 Ko\u00e7man University","place":["Mu\u011fla, T\u00fcrkiye"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,9,23]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","first-page":"Article 100646","DOI":"10.1016\/j.emcon.2026.100646","article-title":"Comparative toxicity of conventional and biodegradable microplastics to the marine algae Chlorella vulgaris: a critical review","volume":"12","author":"Acharjee","year":"2026","journal-title":"Emerg.
