Two laccase isoenzymes (LacA and LacB) were isolated from a novel Trichoderma harzianum S7113 isolate employing ammonium sulfate precipitation, Sephadex G100, DEAE Sepharose ion exchange chromatography. The molecular weights of the purified LacA LacB laccases estimated to be 63 48 kDa, respectively. two had their optimum activities at same temperature (50 °C), but slightly different pH values (pH 3.0 for 2.5 LacB). thermal stability 40 °C 9.0. also showed high level specific activity toward...
Mixed transition metal (Co, Mn, and Cu) oxide electrocatalysts anchored on different carbon supports for oxygen reduction reaction.
Although microbial fuel cells (MFCs) represent a promising technology for capturing renewable energy from wastewater, their scaling-up is significantly limited by slow-rate cathodic oxygen reduction reaction (ORR) and the development of resilient anodic community. In this study, mixed transition metal oxides nickel copper (Ni Cu), supported on graphene (G) (NiO-CuO/G) electrocatalyst, were synthesized tested as cost-effective cathode ORR in MFCs. Electrochemical measurements electrocatalyst...
When a mixed-culture microbial electrolysis cell (MEC) is fed with fermentable substrate, such as glucose, significant fraction of the substrate's electrons ends up methane (CH4) through hydrogenotrophic methanogenesis, an outcome that undesired. Here, we show free ammonia-nitrogen (FAN, which NH3) altered glucose fermentation pathways in batch MECs, minimizing production H2, "fuel" for methanogens. Consequently, Coulombic efficiency (CE) increased: 57% 0.02 g FAN/L fed-MEC, compared to 76%...
Abstract Hexavalent chromium [Cr(VI)] is one of the most carcinogenic and mutagenic toxins, commonly released into environemt from different industries, including leather tanning, pulp paper manufacturing, metal finishing. This study aimed to investigate performance dual chamber microbial fuel cells (DMFCs) equipped with a biocathode as alternative promising remediation approaches for biological reduction hexavalent instantaneous power generation. A succession batch under preliminary diverse...
Over the past few decades, there has been a growing concern regarding fate and transport of pharmaceuticals, particularly antibiotics, as emerging contaminants in environment. It proposed that presence antibiotics at concentrations typically found wastewater can impact dynamics bacterial populations facilitate spread antibiotic resistance. The efficiency currently-used treatment technologies eliminating pharmaceuticals is often insufficient, resulting release low these compounds into In this...
The energy value of the organic matter in landfill leachate can be captured with a microbial electrolysis cell (MEC), which oxidizes compounds at an anode and generates H<sub>2</sub>gas cathode.
This paper presents an evaluation of a combined wastewater treatment train consisting anaerobic hybrid reactor (AHR) followed by downflow hanging sponge (DHS) system. The system was operated at total constant hydraulic retention time (HRT) 8 h (AHR: 6.0 and DHS: 2.0 h) average organic loading rate 1.9 kg COD/m3.d for AHR 2.1 the DHS. able to remove 95 89% BOD5total CODtotal with residual values in final effluent only 10 49 mg/L, respectively. Ammonia concentration reduced 83%. geometric mean...
ABSTRACT When anode‐respiring bacteria (ARB) respire electrons to an anode in microbial electrochemical cells (MXCs), they harvest only a small amount of free energy. This means that ARB must have high substrate‐oxidation rate coupled with ratio used for respiration compared total removed by substrate utilization. It also are especially susceptible inhibition slows or lowers their biomass yield. Using several techniques, we show relatively ammonium‐nitrogen (TAN) concentration (2.2 g TAN/L)...
Because of its low-lying location, urbanization, and inadequate infrastructure, Jakarta (Indonesia) has experienced an increase in annual flooding events, rising from average five significant floods per year the 1990s to over 20 annually (2010-2020). With climate change exacerbating extreme weather encounters escalating risks flooding. Although recurrent is exacerbated by non-point source (NPS) pollution such as urban runoff agricultural discharge that contribute 40% total pollutants leading...
