“…Further to this, ammonia emissions of air-cathode MFCs pose a serious environmental and health threat but the control and mitigation of such emissions have not been studied yet. Subsequently, Li et al have recently reported the characterisation and control of ammonia emissions in MFCs 206. MFC technology has also been proposed as a suitable method for air purification by removing ammonia from air.…”

“…To make the cathode, a piece of stainless-steel mesh was curled to form a cylinder 25 mm in length and 7 mm in diameter (the working area was around 5.5 cm 2 ). Then, it was projected by the catalyst mixture (activated carbon, carbon black, and PVDF) described in previous reports [ 27 , 28 ]. One layer of denim fabric was wrapped around the cylinder surface and acted as a separator.…”

“…To characterize the electrochemical performance of the CS, cyclic voltammetry (CV) was conducted using an electrochemical workstation (CH Instruments, Model 680, CHI760D). Referring to previous studies [ 27 , 30 , 31 ], the anode was connected to the working electrode (WE), an Ag/AgCl (3M KCl) salt electrode was used as a reference electrode (RE), and a Pt counter electrode (CE) was employed for closing the anode. The electrolyte contained 5 mM K 3 [Fe(CN) 6 ], 5 mM K 4 [Fe(CN) 6 ], and 0.1 M NaCl.…”

“…The long-term performance of the sensor was also monitored. As biofilm detachment and accumulation can affect the current generation of MFC-based sensors [ 19 , 26 , 27 ], the CS in this study was designed to contain a screw bottom to collect and remove the detached biofilm. During the experiment, the CS obtained a quick response, a large detection range, and an excellent linear relationship (R 2 higher than 0.98) between glucose concentrations and peak currents.…”

The development of a reusable and low-cost urine glucose sensor can benefit the screening and control of diabetes mellitus. This study focused on the feasibility of employing microbial fuel cells (MFC) as a selective glucose sensor for continuous monitoring of glucose levels in human urine. Using MFC technology, a novel cylinder sensor (CS) was developed. It had a quick response time (100 s), a large detection range (0.3–5 mM), and excellent accuracy. More importantly, the CS could last for up to 5 months. The selectivity of the CS was validated by both synthetic and actual diabetes-negative urine samples. It was found that the CS’s selectivity could be significantly enhanced by adjusting the concentration of the culture’s organic matter. The CS results were comparable to those of a commercial glucose meter (recovery ranged from 93.6% to 127.9%) when the diabetes-positive urine samples were tested. Due to the multiple advantages of high stability, low cost, and high sensitivity over urine test strips, the CS provides a novel and reliable approach for continuous monitoring of urine glucose, which will benefit diabetes assessment and control.

Öz: Nüfus artışı ve endüstriyel gelişme nedeniyle küresel enerji ihtiyacı ve enerji tüketimi endişe verici bir oranda artmaktadır. Artan enerji talebini karşılamak için alternatif yenilenebilir enerji kaynaklarına ihtiyaç vardır. Mikrobiyal yakıt hücreleri (MYH'ler) atıklardan doğrudan elektrik üretebilmesi ve eş zamanlı olarak atıkların arıtımını gerçekleştirebilmesinden dolayı yenilenebilir enerji üretimi açısından son yıllarda oldukça dikkat çekmektedir. Diğer taraftan mikroalgler, bünyelerinde enerji değeri yüksek bileşikleri depolaması ve fotosentez yoluyla CO2'yi uzaklaştırarak oksijen üretmesi nedeniyle yenilenebilir enerji üretimi alanında ve çevresel uygulamalarda ön plana çıkmıştır. Son yıllarda mikroalglerin MYH sistemlerinde kullanılması ile mikroalglerin MYH'nin verimliliğini artırabildiği ve biyoelektrik üretimi için uygun maliyetli ve sürdürülebilir bir yaklaşım sağlayabildiği anlaşılmıştır. Mikroalg tabanlı MYH'ler (MT-MYH) diğer MYH sistemlerine kıyasla daha fazla sürdürülebilir olmasına rağmen, şu an literatürdeki veriler yetersizdir. Bu sistemlerin verimliliğini artırmak ve büyük ölçekli uygulamaların yaygınlaşabilmesi için bu sistemler üzerine yapılan araştırmaların arttırılması gerekmektedir. Bu çalışmada sürdürülebilir bir biyoenerji üretimi için mikroalg tabanlı MYH'ler detaylı bir şekilde analiz edilerek ele alınmıştır.
