The performances and microbiology of three singlechamber, air-cathode, membraneless MFCs with the Organic Fraction of Municipal Solid Waste (OFMSW) as feedstock were investigated. Power Density (PD), Current Density (CD), organic load (COD, BOD5, TOC) removal were evaluated. As to bacteria, lactobacilli were prevalent at the anode of all MFCs. Lactobacillus casei electroactivity was further studied in two-chamber MFCs, achieving a maximum PD of 77 mW/m3, with glucose as source of energy. With an electrodes distance of 2.5 cm, fuel pH was 6.8±1 and a Pseudomonas aeruginosa strain producing abundant pigments grew at the cathode. Even if operating in different conditions (O2 availability, external load, initial pH, electrodes distance), all MFCs gave evidence of a possible utilization of OFMSW as source of electric power (10.8 mW/m2kgwaste) and current (158 mA/m2kgwaste), with a significant organic load removal (up to 80.4% COD, 97% BOD5 and 83.2% TOC).

Abstract
The performances and microbiology of three singlechamber, air-cathode, membraneless MFCs with the Organic Fraction of Municipal Solid Waste (OFMSW) as feedstock were investigated. Power Density (PD), Current Density (CD), organic load (COD, BOD5, TOC) removal were evaluated. As to bacteria, lactobacilli were prevalent at the anode of all MFCs. Lactobacillus casei electroactivity was further studied in two-chamber MFCs, achieving a maximum PD of 77 mW/m3, with glucose as source of energy. With an electrodes distance of 2.5 cm, fuel pH was 6.8±1 and a Pseudomonas aeruginosa strain producing abundant pigments grew at the cathode. Even if operating in different conditions (O2 availability, external load, initial pH, electrodes distance), all MFCs gave evidence of a possible utilization of OFMSW as source of electric power (10.8 mW/m2kgwaste) and current (158 mA/m2kgwaste), with a significant organic load removal (up to 80.4% COD, 97% BOD5 and 83.2% TOC).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
