Generating electricity using microbial fuel cell powered by benthic mud collected from two locations in Akure was carried out. The locations were Riverbed of FUTA and Apatapiti area of Akure. This was achieved by building anode and cathode containers connected together by a salt bridge and an external circuit was made to transfer the electrons from the anode to the cathode. Bacteria and fungi were isolated from the benthic mud for eight days using standard microbiological techniques. Lactobacillus plantarum, Escherichia coli, Bacillus subtilis, Enterobacter aerogenes, Trichoderma sp, Mucor sp and Alterania sp; Lactobacillus plantarum, Escherichia coli, Pseudomonas aeruginosa, Bacillus subtilis, Myrothecium sp and Geotrichum candidum were bacteria and fungi isolated from the benthic mud of Apatapiti area and Riverbed of Futa, Akure respectively. This was used for the generation of electricity using unsterilized mud sample and the control setup was sterilized mud from same source. The set-up was monitored every 24hrous to determine the voltage and current generated. The pH, concentration and temperature were measured. The temperature remains constant throughout the experiment. The set-up were operated at a normal temperature of 27oC and 29oC for Riverbed of FUTA and Apatapiti area of Akure respectively. The peak voltage was between 182.5V and 192.5V and current produced from the main set-up was between 0.3A to 0.53A for Futa river bed while for Apatapiti area of Akure the peak voltage and current were 192.5V and 0.3A respectively. Higher microbial population, current and voltage were observed to be generated in River bed of Futa than Apatapiti area. The difference in the voltage and current and the control set-up shows that anaerobic microorganisms are capable of producing electricity from microbial fuel cell under appropriate conditions.

Rapid consumption of renewable energy resources has led to development of an alternative source of energy. Fuel cell technology is a reliable and sustainable source of energy which was developed. Microbial fuel cell is a type which uses active micro-organisms as catalysts for production of electricity. The micro-organisms degrade the organic substrate to release protons and electrons which generate a potential difference across the cell. Our study focused on the generation of electricity from human urine using microbial fuel cell system. Specific bacteria were used as inoculum at anaerobic anode chamber and salt solution was supplied at aerobic cathode. The chambers were connected using salt bridge which would facilitate ion transfer. This made the system cost effective. The potential difference generated was measured using digital multi-meter.

<p class="PageNumber1">Kalimantan merupakan pulau yang terkenal akan sektor  pertambangan salah satunya di daerah delta Mahakam, yang dalam proses eksploitasinya berpotensi menghasilkan limbah logam berat, seperti logam berat Cr<sup>6+</sup>. Pencemaran logam Cr<sup>6+</sup> cukup sulit untuk terurai dilingkungan dan bersifat karsinogenik, karena dengan konsentrasi kecil saja dapat menimbulkan tingkat keracunan yang sangat tinggi pada makhluk hidup, sehingga pengolahan terhadap limbah tersebut sangat penting. <em>Microbial Fuel Cell</em> merupakan suatu metode yang dapat membantu proses pengolahan limbah dengan cara mereduksi Cr<sup>6+</sup> menjadi Cr<sup>3+</sup> dengan katalisis mikrobiologis. Penelitian ini menggunakan metode reaktor <em>double-chamber</em> yaitu terdapat ruang anoda yang berisi bakteri anaerob dan <em>basic anolyte</em>, sedangkan pada ruang katoda terdapat kalium dikromat dengan konsentrasi 18 mg/L dan variasi pH 3, 4 dan 5 yang dilakukan selama 10 hari. Kondisi pH optimum pada proses reduksi terjadi pada pH 4 dengan besar persen penurunan sekitar 98%. Dan produksi listrik tertinggi pada hari ke-2 pada variasi pH 3 dengan nilai power density sebesar sebesar 11, 06 mW/m<sup>2</sup>.</p>

This paper focuses on determination of the influence of electrochemically active mi­cro­or­ga­ni­sms on the transmission of electrons from the respiratory enzymes to the electrode and as­sembling of exoelectrogens to the simulated wastewater medium. In this study, the total of eight microorganisms were experimentally tested to exhibit growth and high iron-reducing ability in the absence of mediators. A major connection was observed between the growth and iron-reduction ability of the micro­organism. The growth and iron-reduction ability were monitored experimentally over time. Based on output data, the screening was done among eight different micro­organisms, where Escherichia coli -K-12 was chosen as the most potent micro­organism for its wide application in a microbial fuel cell (MFC). In the present study, various biochemical process factors were optimized statistically using Tagu­chi metho­dology for the rapid development of growth and iron-reducing assay conditions. The design of various experimental trials was carried out using five process factors at three levels with orthogonal arrays (OA) layout of L18. Five process factors, including quantity of lactose, volume of trace element solution, inoculum percentage, pH, and temperature, were taken into consideration as imperative process factors and optimized for evaluation of growth of bacteria and iron reduction ability. The larger-is-best signal to noise (S/N) ratio, together with analysis of variance ANOVA, were used during optimization. Anticipated results demonstrated that the enhanced bacterial growth of 124.50 % and iron reduction ability of 112.6 % can be achieved with 8 g/L of lactose, 2 ml of trace element solution, 4 % (v/v) of inoculum, pH 7, and temperature of 35 oC. Furthermore, the growth and iron reduc­tion time profiles of Escherichia coli-K12 were performed to determine its feasibility in MFC. Open circuit voltage of 0.555 V was obtained over batch study on a single chamber microbial fuel cell (SCMFC).

The study aims to synthesize and examine the biological activity of mono- and binuclear platinum (II) and palladium (II) complexes containing terminal and bridging nitrite ligands against the test cultures of Bacillus subtilis B4647, Aspergillus brasiliensis (niger) F679, Pseudomonas aeruginosa B8243, and Escherichia coli. Through the interaction of mononuclear platinum (II) and palladium (II) complexes, dimeric complexes having nitrite ligands were synthesized. The composition and structure of these complexes were established using elemental analysis, conductometry, potentiometry, cryoscopy, infrared spectroscopy, X-ray diffraction analysis, and X-ray fluorescence analysis. A way to coordinate nitrite ligands with the central atom was established. Antimicrobial and antifungal properties were evaluated according to the capability of the synthesized complexes to inhibit the activity of bacteria and fungi via diffusion in agar and in vitro dilution. The minimum inhibitory and bactericidal concentrations of the complexes suppressing the visible growth of microorganisms and fungi, as well as exhibiting their bactericidal effect, ranged from 62.5–125 μmol/dm3. The obtained results revealed a high activity of the palladium (II) binuclear complex of the non-electrolytic type and the platinum (II) binuclear complex of the cationic type. Unlike mononuclear complexes, palladium and platinum binuclear complexes demonstrate higher antibacterial activity. Antibacterial effectiveness exhibited by the palladium complex of the non-electrolytic type against bacteria Bacillus subtilis and Escherichia coli, as well as fungi Aspergillus niger, is more pronounced. The only exception is the antimicrobial activity of the palladium complex against Pseudomonas aeruginosa, which is comparable to that of the binuclear platinum complex of the cationic type. By changing the structure of the complex, the composition and charge of the inner sphere, the number of coordination centers, as well as the nature and denticity of ligands, it is possible to achieve a higher toxic effect of the complexes against bacteria and fungi.
