The films were transparent and resulted in small colour alterations when applied over a coloured surface (\u0394Eab below 12.6 in the five different colours tested). Moreover, scanning electron microscopy showed that the EPS films were dense and compact, with a smooth surface. High water vapour permeabilities were observed (2.7\u20136.1 \u00d7 10\u221211 mol m\u22121 s\u22121 Pa\u22121), which are characteristic of hydrophilic polysaccharide films. The films were also characterised in terms of barrier properties to oxygen and carbon dioxide. Interestingly, different behaviours in terms of their mechanical properties under tensile tests were observed: three of the EPS films were ductile with high elongation at break (\u03b5) (35.6\u201347.0%), low tensile strength at break (\ua786) (4.55\u201311.7 MPa) and low Young\u2019s modulus (\u03b5m) (10\u201393 MPa), whereas the other three were stiffer and more resistant with a higher \ua786 (16.6\u201323.6 MPa), lower \u03b5 (2.80\u20135.58%), and higher \u03b5m (597\u20131100 MPa). These properties demonstrate the potential of Alteromonas sp. EPS films to be applied in different areas such as biomedicine, pharmaceuticals, or food packaging.<\/jats:p>","DOI":"10.3390\/polym14204442","type":"journal-article","created":{"date-parts":[[2022,10,21]],"date-time":"2022-10-21T00:34:30Z","timestamp":1666312470000},"page":"4442","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Characterisation of Films Based on Exopolysaccharides from Alteromonas Strains Isolated from French Polynesia Marine Environments"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6143-9170","authenticated-orcid":false,"given":"Patr\u00edcia","family":"Conc\u00f3rdio-Reis","sequence":"first","affiliation":[{"name":"Associate Laboratory i4HB\u2014Institute for Health and Bioeconomy, NOVA School of Science and Technology, NOVA University of Lisbon, 2829-516 Caparica, Portugal"},{"name":"UCIBIO\u2014Applied Molecular Biosciences Unit, Department of Chemistry, NOVA School of Science and Technology, NOVA University of Lisbon, 2829-516 Caparica, Portugal"}]},{"given":"Jo\u00e3o R.","family":"Pereira","sequence":"additional","affiliation":[{"name":"Associate Laboratory i4HB\u2014Institute for Health and Bioeconomy, NOVA School of Science and Technology, NOVA University of Lisbon, 2829-516 Caparica, Portugal"},{"name":"UCIBIO\u2014Applied Molecular Biosciences Unit, Department of Chemistry, NOVA School of Science and Technology, NOVA University of Lisbon, 2829-516 Caparica, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4117-5582","authenticated-orcid":false,"given":"V\u00edtor D.","family":"Alves","sequence":"additional","affiliation":[{"name":"LEAF\u2014Linking Landscape, Environment, Agriculture and Food, Associated Laboratory TERRA, Instituto Superior de Agronomia, Universidade de Lisboa, 1349-017 Lisboa, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5342-477X","authenticated-orcid":false,"given":"Ana R.","family":"Nabais","sequence":"additional","affiliation":[{"name":"LAQV-REQUIMTE, Department of Chemistry, NOVA School of Science and Technology, FCT NOVA, Universidade NOVA de Lisboa, 2829-516 Caparica, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9620-6286","authenticated-orcid":false,"given":"Lu\u00edsa A.","family":"Neves","sequence":"additional","affiliation":[{"name":"LAQV-REQUIMTE, Department of Chemistry, NOVA School of Science and Technology, FCT NOVA, Universidade NOVA de Lisboa, 2829-516 Caparica, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6878-1040","authenticated-orcid":false,"given":"Ana C.","family":"Marques","sequence":"additional","affiliation":[{"name":"CENIMAT|i3N, Department of Materials Science, School of Science and Technology, NOVA University Lisbon and CEMOP\/UNINOVA, 2829-516 Caparica, Portugal"}]},{"given":"Elvira","family":"Fortunato","sequence":"additional","affiliation":[{"name":"CENIMAT|i3N, Department of Materials Science, School of Science and Technology, NOVA University Lisbon and CEMOP\/UNINOVA, 2829-516 Caparica, Portugal"}]},{"given":"Xavier","family":"Moppert","sequence":"additional","affiliation":[{"name":"Pacific Biotech BP 140 289, Arue Tahiti 98 701, French Polynesia"}]},{"given":"Jean","family":"Gu\u00e9zennec","sequence":"additional","affiliation":[{"name":"AiMB (Advices in Marine Biotechnology), 17 Rue d\u2019Ouessant, 29280 Plouzan\u00e9, France"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4000-1836","authenticated-orcid":false,"given":"Maria A.M.","family":"Reis","sequence":"additional","affiliation":[{"name":"Associate Laboratory i4HB\u2014Institute for Health and Bioeconomy, NOVA School of Science and Technology, NOVA University of Lisbon, 2829-516 Caparica, Portugal"},{"name":"UCIBIO\u2014Applied Molecular Biosciences Unit, Department of Chemistry, NOVA School of Science and Technology, NOVA University of Lisbon, 2829-516 Caparica, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9430-4640","authenticated-orcid":false,"given":"Filomena","family":"Freitas","sequence":"additional","affiliation":[{"name":"Associate Laboratory i4HB\u2014Institute for Health and Bioeconomy, NOVA School of Science and Technology, NOVA University of Lisbon, 2829-516 Caparica, Portugal"},{"name":"UCIBIO\u2014Applied Molecular Biosciences Unit, Department of Chemistry, NOVA School of Science and Technology, NOVA University of Lisbon, 2829-516 Caparica, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2022,10,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1582","DOI":"10.1016\/j.carbpol.2010.10.010","article-title":"Characterization of biodegradable films from the extracellular polysaccharide produced by Pseudomonas oleovorans grown on glycerol byproduct","volume":"83","author":"Alves","year":"2011","journal-title":"Carbohydr.
