Generación de biogás mediante una estrategia de bioaumentación con un consorcio microbiano

Abstract

Abstract: Global warming is the result of environmental pollution caused mainly by Methane (CH4) gas. The manure of cattle is a source of generation of CH4 its capture would help to avoid the deterioration of the environment and it can also be used as a source of clean energy. CH4 is obtained by digestion of lignin by physical, chemical or biological methods. In this study, the generation of biogas by a biological method was evaluated with a bioaugmentation strategy of a microbial consortium in cattle manure. The concentration of the microbial consortium in the mixture was 10% v / v in treatment T1, from which 3.10 ± 0.32 L of biogas was obtained, against 2.93 ± 0.33 L of biogas in treatment T2 that was not inoculated. The generation of biogas had an increase of 5.80% in treatment T1 over treatment T2. These results open the possibility of improving biogas generation with additional studies where different concentrations of microorganisms are used.
