Poly(lactide) (PLA) films obtained by thermoforming or solution-casting were modified by diffuse coplanar surface barrier discharge plasma (300 W and 60 s). PLA films were used as hot-melt adhesive in joints in oak wood. It was demonstrated that lap shear strength increased from 3.4 to 8.2 MPa, respectively, for the untreated and plasma-treated series. Pull-off tests performed on particleboard for the untreated and treated PLA films showed 100% cohesive failure. Pull-off strength tests on solid oak demonstrated adhesion enhancement from 3.3 MPa with the adhesion failure mode to 6.6 MPa with the cohesion failure mode for untreated and treated PLA. XPS revealed that carbonyl oxygen content increased by two-to-three-fold, which was confirmed in the Fourier-transform infrared spectroscopy experiments of the treated PLA. The water contact angle decreased from 66.4° for the pristine PLA to 49.8° after treatment. Subsequently, the surface free energy increased from 47.9 to 61.05 mJ/m2. Thus, it was clearly proven that discharge air plasma can be an efficient tool to change surface properties and to strengthen adhesive interactions between PLA and woody substrates.

Production of electricity from wastewater in microbial fuel cells is possible due to the cooperation of hydrolytic, fermentative, and electrogenic microorganisms coexisting in a consortium. In this article, we present results that indicate that we can stimulate electrical current production from wastewater, from which power could not be produced without influencing the growth of a microbial consortium through preconditioning. The wood industry wastewater was thermally preconditioned at 45 °C before introducing it to microbial fuel cells which resulted in changing microbial consortium composition by the development of new species. In the anodes of microbial fuel cells that were fed preconditioned wastewater, we identified, by the means of metagenomic analysis, mixed fungi-bacteria syntrophic consortium that was capable of producing electricity from wood industry wastewater. The developed syntrophic consortium was dominated by fungi of the Trichocomaceae sp. and two bacteria species: Achromobacter insolitus and Geobacter sulfurreducens. None of these species were present in raw wastewater. Power was not generated in microbial fuel cells that were fed raw wastewater, but wastewater preconditioning stimulated power production at 0.33 W/m2 what responded to 1 A/m2 current density. The developed consortium decomposed cellulose present in wastewater into glucose and fermented it into acids and alcohols. We showed that stimulation of power production may be driven through substrate preconditioning before it is used in microbial fuel cells. By selecting growth conditions for a consortium, we may regulate its microbial composition and facilitate production of an electrical current from substrates that could not previously be used in microbial fuel cells.

Although the wood-based panel industry is not considered to be a water-consuming sector, it generates ca. 600 M m3 of wastewater every year on a global scale. The wastewater is usually highly polluted and environmentally toxic even after dilution. Common wastewater treatment techniques require high-energy input or addition of various chemicals to the treated wastewater, which cause secondary pollution and production of toxic sludge. Microbial fuel cells (MFCs) have become an attractive technology, allowing for zero-energy treatment of various types of wastewater with simultaneous production of electric current. Recent investigations have shown that MFCs can also be utilized for sustainable treatment and energy production from the wastewater generated by the wood-based panel industry. This article contains a critical summary of the investigations in this field as well as a discussion of the research needed and perspectives for the future.

Microbial fuel cell (MFC) has the potential to become a promising sustainable technology of wastewater treatment. Usually, the investigations on MFCs are aimed at maximized power production in the system. In this article, we focused on the optimization of wood industry wastewater treatment in MFC, in combination with municipal wastewater as a source of microorganisms. We investigated the influence of different external resistance (2000 Ω, 1000 Ω, 500 Ω, and 100 Ω) on power density and wastewater treatment efficiency (chemical oxygen demand (COD) removal) in 1-month MFC operation time. We found that the highest COD removal was for MFCs under R = 1000 Ω after 22 days of MFC operation, while the highest current density was obtained for the lowest applied resistance. The results imply that wastewater treatment parameters such as resistance and time of MFC operation should be a subject of optimization for each specific type of wastewater used, in order to maximize either wastewater treatment efficiency or power production in MFC. Thus, optimization of power production and COD removal efficiency in MFCs need to be run separately as different resistances are required for maximizing these two parameters. When COD removal efficiency is a subject of optimization, there is no universal value of external resistance, but it should be set to the specific wastewater characteristics.

Fungi are among the microorganisms able to generate electricity as a result of their metabolic processes. Throughout the last several years, a large number of papers on various microorganisms for current production in microbial fuel cells (MFCs) have been published; however, fungi still lack sufficient evaluation in this regard. In this review, we focus on fungi, paying special attention to their potential applicability to MFCs. Fungi used as anodic or cathodic catalysts, in different reactor configurations, with or without the addition of an exogenous mediator, are described. Contrary to bacteria, in which the mechanism of electron transfer is pretty well known, the mechanism of electron transfer in fungi-based MFCs has not been studied intensively. Thus, here we describe the main findings, which can be used as the starting point for future investigations. We show that fungi have the potential to act as electrogens or cathode catalysts, but MFCs based on bacteria–fungus interactions are especially interesting. The review presents the current state-of-the-art in the field of MFC systems exploiting fungi.

Electrogenic microorganisms are the heart of microbial fuel cell (MFC) systems that enable the conversion of waste into bioelectricity. Bacteria able to generate current, found in various natural and anthropogenic environments, need simple substrates such as acetate or glucose. Complex substrates are utilized by bacterial consortia made up of strains that exhibit a wide range of enzymatic and metabolic activity that determines the type of substrate they are able to degrade. The characteristics of the environment that a bacterial consortium develops in strongly affect the consortium's species composition and electrogenic potential. This study presents the first attempt to use industrial raw wastewater from the hydrothermal treatment of wood (WHTW) as a substrate and a source of bacterial consortia for MFC, so that such wastewater could simultaneously be treated and produce bioelectricity. The power generated in MFCs fed with WHTW was enhanced remarkably from 70 to 360mW/m when municipal wastewater was introduced into the reactor. An analysis of the bacterial composition of these two types of wastewater revealed that the WHTW was dominated by the genera Thermoanaerobacterium and Paenibacillus while in the biofilm developed in the anode the main genera were Hydrogenophilus and Anaerobaculum. It has been shown for the first time that highly polluted wood industry wastewater may be effectively treated in MFC systems and the use of appropriate bacterial consortium may result in enhancing power generation accompanying wastewater treatment.

The abundance of cellulosic wastes make them attractive source of energy for producing electricity in microbial fuel cells (MFCs). However, electricity production from cellulose requires obligate anaerobes that can degrade cellulose and transfer electrons to the electrode (exoelectrogens), and thus most previous MFC studies have been conducted using two-chamber systems to avoid oxygen contamination of the anode. Single-chamber, air-cathode MFCs typically produce higher power densities than aqueous catholyte MFCs and avoid energy input for the cathodic reaction. To better understand the bacterial communities that evolve in single-chamber air-cathode MFCs fed cellulose, we examined the changes in the bacterial consortium in an MFC fed cellulose over time. The most predominant bacteria shown to be capable electron generation was Firmicutes, with the fermenters decomposing cellulose Bacteroidetes. The main genera developed after extended operation of the cellulose-fed MFC were cellulolytic strains, fermenters and electrogens that included: Parabacteroides, Proteiniphilum, Catonella and Clostridium. These results demonstrate that different communities evolve in air-cathode MFCs fed cellulose than the previous two-chamber reactors.

Highlights•Novel construction of all-solid-state potentiometric sensor array designed for physiological measurements has been described.•Presented sensor array approach indicates high sensitivity, low response time and high potential stability.•Sensor array was successfully applied to simultaneous determination of potassium, sodium, chloride ions and pH in model physiological solution and in Caco-2 cell monolayer. AbstractA novel construction of all−solid-state potentiometric sensor array designed for physiological measurements has been presented. The planar construction and elimination of liquid phase creates broad opportunities for the modifications in the sensing part of the sensor. The designed construction is based on all−solid-state ion-selective electrodes integrated with the ionic-liquid based reference electrode. Work parameters of the sensor arrays were characterized. It has been shown that presented sensor design indicates high sensitivity (55.2 ± 1 mV/dec, 56.3 ± 2 mV/dec, 58.4 ± 1 mV/dec and 53.5 ± 1 mV/pH for sodium-, potassium-, chloride- and pH-selective electrodes, respectively in 10−5 – 10−1.5 M range of primary ions), low response time (t95 did not exceed 10 seconds), high potential stability (potential drift in 28-hour measurement was ca. ± 2 mV) and potential repeatability ca. ± 1 mV. The system was successfully applied to the simultaneous determination of K+, Cl−, Na+ and pH in the model physiological solution and for the ion flux studies in human colon epithelium Caco-2 cell line as well.

Mediatorless cellulose-fed microbial fuel cell (MFC) is a bioelectrochemical system that converts cellulose into energy through cellulose-hydrolyzing and electrogenic activity of bacteria. In the paper it has been presented that Enterobacter cloacae isolated from termite gut exhibited both cellulose-degrading and exoelectrogenic activities that make it a valuable strain to be used in a cellulose-fed MFC. The maximum power and current densities obtained from the cellulose-fed MFC were 185 mW/m2 and 2.4 A/m2, respectively. SEM micrographs of the anode showed that E. cloacae formed an expanded fibria system bounding bacteria cells into network attached to the electrode surface.

The activation of mitochondrial potassium channels induces cytoprotection in various cell types. Hence, the identification of ion channels present in the inner mitochondrial membrane of keratinocytes is important in distinguishing possible protective mechanisms in these cells. In this paper, inner membrane mitochondrial ion channels of the human keratinocyte HaCaT cell line were investigated using a patch-clamp technique. We observed potassium-selective channel activity with a conductance of 83 pS at positive voltages. The I–V curve indicates that the observed channel has rectifying properties. Moreover, the channel activity was inhibited by acidic pH and 1 mM lidocaine. Using reverse transcriptase–PCR, we found an mRNA transcript for the TASK-3 (tandem pore domain acid-sensitive K channels) channel. We observed co-localization of the TASK-3 protein and a mitochondrial marker in the mitochondria of HaCaT cells. Additionally, we showed that TASK-3 knockdown HaCaT cells markedly decreased viability after UVB radiation exposure compared with control cells. In summary, the single-channel activity and properties of a mitochondrial potassium channel in a keratinocyte HaCaT cell line have been described

An ion-selective multielectrode bisensor system is designed to ensure reliable real-time concentration measurements of sodium, potassium, chloride, and pH in a small volume of biological liquid bathing a living human bronchial epithelial cell monolayer. The bisensor system allows the monitoring of major ions, which are simultaneously transported through the epithelia in both directions.

The electrolyte transport system across human airway epithelium followed by water movement is essential for the normal mucociliary clearance that allows the maintenance of the aseptic condition of the respiratory tract. The function of epithelial cells is to control and regulate ionic composition and volume of fluids in the airways. Various types of proteins taking part in assuring effective ions and water transport in apical and basolateral membranes of the airway epithelium have been found (e.g., CFTR, ENaC, CaCC, ORCC, potassium channels, NaKATPase, aquaporins).

The development of the miniaturised electrochemical cell integrated on epoxy-glass laminate support is reported. Potassium-selective microelectrodes based on valinomycin and two polymeric matrices [plasticized poly(vinyl chloride) and polyurethane] have been fabricated on planar Au or Ag/AgCl transducers. Polymeric layers containing ionic liquid were cast on the surface of Ag/AgCl microelectrodes to form the reference half-cells. Performances of the ion-sensitive and reference microelectrodes (i.e., ion-selectivity, slopes of calibration curves, signal stability and repeatability, long-term stability) were studied. The influence of the method of membrane deposition on sensor characteristics was not significant, however the microelectrodes with polyurethane membranes exhibited better durability. Theoretical calibration curves were obtained when K+-selective electrodes and reference electrodes were integrated on a single substrate. The designed electrochemical cell may be helpful in further studies devoted to the development of miniaturised electrode arrays for multi-component analysis or electronic tongues purposes.

An integrated array of solid-state ion-sensitive microelectrodes was applied for the construction of planar electronic tongue. The fabrication of the device based on PCB technology was described—the method is simple, fast and not expensive. The ion-selective sensor array was obtained by the deposition of PVC membranes, exhibiting different sensitivities towards various ionic species, on the surface of planar Au microelectrodes. The miniaturized electronic tongue system was checked in the recognition of a brand of orange juice. High ability of the system for the recognition of juice origin was noticed.

A method for the fabrication of ion-selective all-solid-state microelectrodes is presented. The ion-to-electron transduction process takes place into the transducer material. In this approach, AgI-Ag2O-V2O5 glasses, which exhibit ionic and electrical conductivity are applied as ion-to-electron transducers of polymeric membrane microelectrodes. All-solid-state electrodes based on potassium-sensitive poly(vinyl chloride) membranes, deposited directly on the surface of glass composites, exhibited theoretical responses. Their selectivity and durability were comparable to planar microelectrodes containing an internal electrolyte immobilized in the intermediate hydrogel layer. The only disadvantage of the proposed structures was their limited reproducibility. Moreover, it was found that the unmodified AgI-Ag2O-V2O5 glasses can be applied as ion-sensitive membrane of solid-state microelectrodes for the determination of Ag+ and I− ions.
