Single-cell biofuel element of simple construction from sanitary parts and testing of its work

[摘要] A model of single-chamber biofuel cell from easily accessible sanitary components (sanitary tees for Sinikon internal sewage pipes and plugs to them) was developed and tested. It is characterized by low cost and easy assembly. As the bioagents the authors used, in particular, the individual strain Micrococcus luteus 1-I, isolated from the active sludge of the petrochemical plant. The proposed single-chamber biofuel cells, based on this strain for 96 hours of the experiment generated an open circuit voltage of up to 480 mV, the current strength was up to 1 mA. Promising bioagents for the developed design were commercial microbiological preparations for cesspools and septic tanks and for composting: biofertilizer "EM-Bio" (LLC "Primorsky EM-Center", Vladivostok); means for cesspools and septic tanks "Doctor Robik" (LLC VIPEKO, Moscow); microbiological fertilizer "Baikal-EM" (OOO "EM-Kooperatsiya", Moscow); microbiological preparation for eliminating odors and recycling "Won!" (IP Dugarova, D.C., Ulan-Ude). The voltage of the open circuit, which was generated in single-chamber biofuel cells' commercial microbiological preparations, increased to 357 - 546 mV for 96 hours of the experiment. The short-circuit current was increased to 597 - 843 μ The specific power of the single-chamber biofuel cells on the basis of all the bioagents, tested in the paper, was quite close and varied in the range 10.2 - 12.7 μW / cm2.
