Corn bran moistened to four levels of moisture content was used for the tests: 20%, 25%, 30% and 35% of dry matter. The pressure-thermal treatment was carried out with the use of a Brikol SJ25 pellet maker and a TS-45 single-screw extruder. In the tests of the extrusion-cooking process, three rotational speeds of the extruder screw were applied: 70, 90 and 110 rpm. The following characteristics were examined: efficiency of the extrusion-cooking and pelleting process, as well as the energy consumption. The water absorption index (WAI), the water solubility index (WSI), bulk density, kinetic strength, structure analysis by the ART\/FTIR method, energy potential and the efficiency of cumulated biogas and cumulated methane per dry mass, as well as fresh mass and fresh organic matter and a series of microscopic pictures were completed. The analysis of the ATR\/FTIR infrared spectra of the tested pelleted and extruded samples showed clear changes at the molecular level. Biogas production of extruded corn bran increased by several percent, as compared to untreated material.<\/jats:p>","DOI":"10.3390\/en14216997","type":"journal-article","created":{"date-parts":[[2021,10,25]],"date-time":"2021-10-25T21:40:21Z","timestamp":1635198021000},"page":"6997","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["The Influence of the Pressure-Thermal Agglomeration Methods of Corn Bran on Their Selected Physicochemical Properties and Biogas Efficiency"],"prefix":"10.3390","volume":"14","author":[{"given":"Karol","family":"Kupryaniuk","sequence":"first","affiliation":[{"name":"Department of Thermal Technology and Food Process Engineering, University of Life Sciences in Lublin, G\u0142\u0119boka 31, 20-612 Lublin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5981-6109","authenticated-orcid":false,"given":"Agnieszka","family":"W\u00f3jtowicz","sequence":"additional","affiliation":[{"name":"Department of Thermal Technology and Food Process Engineering, University of Life Sciences in Lublin, G\u0142\u0119boka 31, 20-612 Lublin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7560-4779","authenticated-orcid":false,"given":"Jakub","family":"Mazurkiewicz","sequence":"additional","affiliation":[{"name":"Laboratory of Ecotechnology, Department of Biosystems Engineering, Pozna\u0144 University of Life Sciences, Wojska Polskiego 50, 60-627 Pozna\u0144, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9449-2234","authenticated-orcid":false,"given":"Tomasz","family":"S\u0142owik","sequence":"additional","affiliation":[{"name":"Department of Power Engineering and Transportation, University of Life Sciences in Lublin, G\u0142\u0119boka 28, 20-612 Lublin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2630-120X","authenticated-orcid":false,"given":"Arkadiusz","family":"Matwijczuk","sequence":"additional","affiliation":[{"name":"Department of Biophysics, University of Life Sciences in Lublin, Akademicka 13, 20-950 Lublin, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,10,25]]},"reference":[{"key":"ref_1","first-page":"269","article-title":"Metody wst\u0119pnego przygotowania biomasy lignocelulozowej do fermentacji metanowej","volume":"7","author":"Bernat","year":"2014","journal-title":"Gaz Woda Tech.
