Five vinasses and bovine manure mixtures in different proportions were compared (v/v): 25-75, 50-50, 75-25, 100-0, and 0-100, with six replications. As reactors, 496 mL glass containers with hermetic seal were used, with 300 mL of active volume under mesophilic conditions (36 ± 1 oC) for 10 days. The pH, total solids, and volatile solids of vinasses, bovine manure, and their mixtures were determined in triplicate. The methane accumulated volume was greater with the 0-100 and 75-25, followed by the 100-0, with 286.23, 286.40, and 225.48 NmL CH4, respectively. Methane yield was higher with 100-0 and 75-25 with 28.27 and 22.77 NmL CH4 g-1 volatile solids, respectively. The Gompertz bacterial growth model showed that the micro-organisms adaptation period in vinasses was longer than in bovine manure. Co- digestion of vinasses and bovine manure in proportion 75-25 % improved the methane production by 26.7 % with respect to the digestion of vinasses alone, and reduced the adaptation time of bacteria to vinasses by 4.12 days. 2022 artículo científico 1665-1456 https://www.redalyc.org/articulo.oa?id=672974941007 https://www.redalyc.org/journal/6729/672974941007/ https://www.redalyc.org/journal/6729/672974941007/html/ https://www.redalyc.org/journal/6729/672974941007/672974941007.epub https://www.redalyc.org/journal/6729/672974941007/movil 10.18633/biotecnia.v24i2.1501 en http://www.redalyc.org/revista.oa?id=6729 Biotecnia application/pdf Universidad de Sonora Biotecnia (México) Num.2 Vol.24 |
