In the present study, xanthan-like EPS produced by Xanthomonas translucens TRK8 was precipitated by ethanol and isopropanol, with the former yielding 9.2 g L\u22121 compared with 6.7 g L\u22121 obtained with the latter. The monosaccharide profile of the TRK8-derived EPS indicated a branched structure composed of rhamnose, mannose, glucose, and galactose residues, containing both \u03b1- and \u03b2-type pyranose units. The rheological properties of the studied EPS were compared with those of commercial xanthan at concentrations of 1\u20133 wt.%. Fitting the obtained data to the Ostwald\u2013de Waele power-law model revealed that the flow behaviour index (n) values were below 1 (\u22120.338, \u22120.499, and \u22120.647, respectively), indicating shear-thinning behaviour (i.e., pseudoplasticity). The potential of the TRK8-derived EPS as a plant protection agent was validated by coating barley seeds with 2 wt.% EPS, resulting in a 28.6% increase in shoot length and a 64.7% increase in root length relative to the oil-stressed control.<\/jats:p>","DOI":"10.3390\/microorganisms14040937","type":"journal-article","created":{"date-parts":[[2026,4,22]],"date-time":"2026-04-22T12:00:32Z","timestamp":1776859232000},"page":"937","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Enhanced Barley Growth in Petroleum-Contaminated Soil Mediated by Xanthan-like Exopolysaccharide of Xanthomonas translucens TRK8"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9251-4452","authenticated-orcid":false,"given":"Ramza","family":"Berzhanova","sequence":"first","affiliation":[{"name":"Department of Biotechnology, Faculty of Biology and Biotechnology, Al-Farabi Kazakh National University, Al-Farabi 71\/19, Almaty 050040, Kazakhstan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8230-4814","authenticated-orcid":false,"given":"Aisulu","family":"Zhuniszhan","sequence":"additional","affiliation":[{"name":"Department of Biotechnology, Faculty of Biology and Biotechnology, Al-Farabi Kazakh National University, Al-Farabi 71\/19, Almaty 050040, Kazakhstan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4457-1705","authenticated-orcid":false,"given":"Gulnur","family":"Tatykhanova","sequence":"additional","affiliation":[{"name":"Institute of Polymer Materials and Technology, Atyrau 1, 3\/1, Almaty 050019, Kazakhstan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1166-7826","authenticated-orcid":false,"given":"Sarkyt","family":"Kudaibergenov","sequence":"additional","affiliation":[{"name":"Institute of Polymer Materials and Technology, Atyrau 1, 3\/1, Almaty 050019, Kazakhstan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gulshara","family":"Abai","sequence":"additional","affiliation":[{"name":"BioClean LLP, Tole bi 289\/14, Almaty 050031, Kazakhstan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7224-2568","authenticated-orcid":false,"given":"Alibek","family":"Kudabayev","sequence":"additional","affiliation":[{"name":"BioClean LLP, Tole bi 289\/14, Almaty 050031, Kazakhstan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-1241-2057","authenticated-orcid":false,"given":"Togzhan","family":"Mukasheva","sequence":"additional","affiliation":[{"name":"Department of Biotechnology, Faculty of Biology and Biotechnology, Al-Farabi Kazakh National University, Al-Farabi 71\/19, Almaty 050040, Kazakhstan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,4,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"155","DOI":"10.1146\/annurev-food-030117-012537","article-title":"Lactic Acid Bacteria Exopolysaccharides in Foods and Beverages: Isolation, Properties, Characterization, and Health Benefits","volume":"9","author":"Lynch","year":"2018","journal-title":"Annu.
