Title: Biogas generation based on a mixture of cow manure with citrus waste and influence of bismuth complexes on gas production
Keywords: anaerobic biofermentation, Bi(III) complexes, biogas, cow manure, methanе production

Abstract: The purpose of present work is to investigate the possibility of biogas production based on cow manure mixed with citrus solid waste, as well as to study the influence of bismuth complexes of sulfamic and p-toluenesulfonic acids on the processes of methanogenesis. The sample mixtures are incubated at 35±1°C, in a nitrogen atmosphere for 24 days. The volume of biogas generated, the percentage content of methane as well as that of carbon dioxide are measured periodically in every two or three days during the experiment. It is found out that the largest amount of biogas is formed for the sample, which contains a bismuth complex of sulfamic acid. Moreover, the sample mixture containing cow manure and solid citrus waste only produces a relatively low percentage concentration of carbon dioxide. Concerning methane content (%) it is worth noting that again the mixture containing cow manure and solid citrus waste only, gives the best methane yield, while the sample containing bismuth complex of sulfamic acid ranks on second place.
