Vinasse has a low pH and high chemical oxygen demand, which can cause land desertification when indiscriminately used as fertilizer. Also, underground water contamination is being observed in some regions. We evaluated the potential of vinasse as nutrient source for biohydrogen and volatile fatty acids production by means of anaerobic consortia. Two different vinasse-based media were proposed, using sugarcane juice or molasses as carbon source, and were compared to fermentation in a sucrose-supplemented medium. Pure cultures (4) and consortia (7) were cultured in the propose media and evaluated for volatile fatty acids (VFAs) and biohydrogen production. The consortium LPBAH1 was selected for fermentation of vinasse supplemented with sugarcane juice, resulting in a higher H2 yield of 7.14molH2/molsucrose and hydrogen content in biogas of approx. 31% after process optimization. Similarly, the optimized process using the consortium LPBAH2 resulted in 3.66 molH2/molsucrose and 32.7% hydrogen content in biogas. The proposed process is of great importance for giving a more rational destination to vinasse and expanding Brazilian energy matrix, reducing the dependence of fossil fuels.115f. : il. algumas color., grafs., tabs.application/pdfDisponível em formato digitalÁcidos graxosBactérias anaeróbiasValorization of vinasse as broth for biological hydrogen and volatile fatty acids production by means of anaerobic bacteriainfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisporreponame:Repositório Institucional da UFPRinstname:Universidade Federal do Paraná (UFPR)instacron:UFPRinfo:eu-repo/semantics/openAccessORIGINALR - T - EDUARDO BITTENCOURT SYDNEY.pdfapplication/pdf2102284https://acervodigital.ufpr.br/bitstream/1884/36032/1/R%20-%20T%20-%20EDUARDO%20BITTENCOURT%20%20SYDNEY.pdfa7ff32e4c48818db8d193bd8cca6c8cbMD51open accessTEXTR - T - EDUARDO BITTENCOURT SYDNEY.pdf.txtExtracted Texttext/plain177039https://acervodigital.ufpr.br/bitstream/1884/36032/2/R%20-%20T%20-%20EDUARDO%20BITTENCOURT%20%20SYDNEY.pdf.txt366ec18d92fc3d9d01bd85a879c4892eMD52open accessTHUMBNAILR - T - EDUARDO BITTENCOURT SYDNEY.pdf.jpgGenerated Thumbnailimage/jpeg1403https://acervodigital.ufpr.br/bitstream/1884/36032/3/R%20-%20T%20-%20EDUARDO%20BITTENCOURT%20%20SYDNEY.pdf.jpge62a3030501587545159c5ed7f997929MD53open access1884/360322024-04-15 17:15:20.912open accessoai:acervodigital.ufpr.br:1884/36032Repositório de PublicaçõesPUBhttp://acervodigital.ufpr.br/oai/requestopendoar:3082024-04-15T20:15:20Repositório Institucional da UFPR - Universidade Federal do Paraná (UFPR)false
