In this research, the toxic effect of limonene and fenchone, two of the main monoterpenes present in vegetable biomasses, and those of 4-terpineol, α-terpineol, and p-cymene, compounds described as main metabolites of limonene degradation, have been assessed. Methane production was totally inhibited at dosed of 1000 mg L-1 of fenchone and limonene and at 600 mg L-1 of p-cymene and 4-terpineol. Based on the methane production rate, the inhibition followed the next trend: α-terpineol << fenchone < limonene ≈ p-cymene < 4-terpineol. Regardless of dosed concentration, monoterpenes were mostly degraded at the end of the experiment (>85%), except p-cymene at 600 mg L-1. Therefore, monoterpenes could entail a high risk of inhibition that can be aggravated by the difficulty to accurately follow their concentration and by the scarce information on their effect on anaerobic process.}, organization = {ENI CBC MED 2014–2020 programme A_B.4.2_0058}, organization = {Spanish Ministry of Science and Innovation TED2021-129599B}, organization = {Andalucia Autonomous Government (EMERGIA20_00114)}, organization = {MCIU/AEI/10.13039/501100011033 JDC2022-050255-I}, organization = {European Union's "NextGenerationEU"/PRTR}, publisher = {Elsevier}, keywords = {Antimicrobial properties}, keywords = {Biodegradation}, keywords = {Inhibition}, keywords = {Metabolites}, keywords = {Toxicity test}, keywords = {Volatile organic compounds}, title = {Assessment of seasonal feedstock changes in long-term anaerobic digestion: Monoterpenes influence on the microbial consortium}, doi = {10.1016/j.biombioe.2025.107674}, author = {Trujillo-Reyes, Ángeles and García Pérez, Ana and Serrano Moral, Antonio and Ramiro García, Javier and Cubero-Cardoso, Juan and Fermoso, Fernando G.}, }
