The phenyl acids phenyl\u2010acetic\u2010(PAA), phenyl\u2010propionic\u2010(PPA), and phenyl\u2010butyric acid (PBA) are such intermediates suspected to negatively affect the microbial community, resulting in a decreased biogas yield.

PBA had the greatest detrimental impact on methanogens across all tested phenyl acids, followed by PPA and PAA. However, in further investigations, it has to be clarified if and how other microorganisms involved in AD are impacted by phenyl acids. A more detailed knowledge will help to better understand disturbances due to phenyl acid emergence caused by the degradation of lignocellulose\u2010 and protein\u2010rich substrates, to ensure a stable AD process even at high loads of these substrates.\n                  <\/jats:p>","DOI":"10.1111\/1758-2229.70082","type":"journal-article","created":{"date-parts":[[2025,3,13]],"date-time":"2025-03-13T01:25:00Z","timestamp":1741829100000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Phenyl Acid Induced Inhibition of Methanogenesis in\n                    <scp>\n                      CO\n                      <sub>2<\/sub>\n                    <\/scp>\n                    Reducing Organisms"],"prefix":"10.1111","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8914-1907","authenticated-orcid":false,"given":"Mathias","family":"Wunderer","sequence":"first","affiliation":[{"name":"Universit\u00e4t Innsbruck Department of Microbiology  Innsbruck Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Martin","family":"Unterkircher","sequence":"additional","affiliation":[{"name":"Universit\u00e4t Innsbruck Department of Microbiology  Innsbruck Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna","family":"Schmidhofer","sequence":"additional","affiliation":[{"name":"Universit\u00e4t Innsbruck Department of Microbiology  Innsbruck Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1734-657X","authenticated-orcid":false,"given":"Eva Maria","family":"Prem","sequence":"additional","affiliation":[{"name":"Universit\u00e4t Innsbruck Department of Microbiology  Innsbruck Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6009-8498","authenticated-orcid":false,"given":"Andreas O.","family":"Wagner","sequence":"additional","affiliation":[{"name":"Universit\u00e4t Innsbruck Department of Microbiology  Innsbruck Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,3,12]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF00693392"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.2166\/wst.2015.165"},{"key":"e_1_2_9_4_1","unstructured":"European Parliament. n.d.\u201cEU Progress Towards Its 2020 Climate Change Goals.\u201dAccessed March 28 2023.https:\/\/www.europarl.europa.eu\/news\/en\/headlines\/society\/20180706STO07407\/eu\u2010progress\u2010towards\u20102020\u2010climate\u2010change\u2010goals\u2010infographic?at_campaign=20234\u2010Green&at_medium=Google_Ads&at_platform=Search&at_creation=DSA&at_goal=TR_G&at_audience=&at_topic=Climate_Change&gclid=EAIaIQobChMI46KW1ZKYgQMVqE\u2010RBR0gtggtEAAYASAAEgLDE_D_BwE."},{"key":"e_1_2_9_5_1","unstructured":"Fehrenbach H.
