Full textThe present work has been prepared within the framework of the European project ERUDESP and describes the research that has been carried out during this work. A bioreactor as a bioelectrochemical flow-cell was designed and realized with the goal to serve for enantiopure bioelectrosynthesis. The work deals with the cell design and screening of different mediators in a batch-cell and multi-cells, the development of different electroorganic and electroenzymatic reactions in an electrochemical batch- and flow-cell. With respect to the flow-cell, the upscaling of electrochemical reactions was carried out in the present work not only for electroorganic but also for electroenzymatic reactions with regard to the final application. A main focus of the present work represents the synthesis of three-dimensional macroporous electrodes in order to increase significantly the active surface. These macroporous structures were obtained by using the template approach. For the preparation of the templates monodisperse polystyrene particles were synthesized in different ways, and then used for the preparation of colloidal crystals serving as templates. As controlled assembly procedures, the Langmuir-Blodgett technique and the controlled evaporation method with subsequent electrodeposition of metals and metal oxides were chosen. With the present process the pore diameter could be exactly controlled by the diameter of the used particles. The approach of the Langmuir-Blodgett technique has been extended and optimized. For the first time, the Langmuir-Blodgett technique could be used with polystyrene particles. The deposition took place in the interspaces of the prepared colloidal crystals and is followed by the dissolving of the particles. Furthermore, the size of the porous electrodes could be upscaled (6 x 6 cm2). The obtained materials showed a very good interconnectivity with an open porosity and a highly increased active surface, which led to an increased electrochemical signal. The prepared porous materials represent a great benefit not only for (bio)electrosynthesis but also in the field of (bio)electroanalysis. In the framework of this work, the use of porous ruthenium oxide electrodes for direct oxidation of NADH with a significantly improved overvoltage was studied. Also in this context the increase of the surface led to an improved current density. Based on the ERUDESP project, the studied techniques for preparing porous electrodes with colloidal crystals were used for further scientific studies. The new variant of the Langmuir-Blodgett technique has also been used for the elaboration of a renewable electrode system where the surface can be simply renewed by applying a positive potential to the porous multilayers (click effect). The porous ruthenium oxide electrodes have not only been studied with respect to the ERUDESP project, but it was also possible to miniaturize this stable porous material as microelectrodes and use them as chemically and mechanically stable pH sensor with an improved signal to noise ratio. In this case the thermal noise decreased due to the porosity of the electrode. Due to the acquired expertise in the field of the preparation of porous microelectrodes, implantable microelectrodes for hand prosthesis were modified with a porous layer on the surface for increasing the active surface and decreasing their impedance.In addition, macroporous multicatalyst layers of platinum and nickel were synthesized for the simultaneous in-situ generation of hydrogen and hydrogenation reaction in the same catalyst system.As a final example for controlled surface structuring, nanoscale platinum islands were in detail examined and biofunctionalized. This led also to a significant increase of the current density

Full textIn real or simulated microgravity, the absence of gravity directs multipotent stem cells from bone marrow to favor adipogenesis at the expense of osteogenesis. This causes a bone loss, commonly found in astronauts during spaceflight. Among existing drug therapies, strontium has a double action, both activating osteogenesis and inhibiting adipogenesis. In this context, the general objective of this project was to demonstrate that strontium may be a good candidate to counteract the microgravity effects. We were particularly interested in small proteins Rho of the GTPases family, which control cell cytoskeleton, cell tension and many signaling pathways. According to the literature, these pathways were also shown to be related to the VEGF singaling or the cell oxidative status, involved in the multipotent stem cells commitment. The first part of this study demonstrated the strontium antioxidant effect on the C3H10T1/2 line as an activator of the GTPase RhoA, allowing the induction of the key antioxidant response gene, Nrf2, and therefore inhibiting adipogenesis. The second part used a 3D cultures model on polystyrene microbeads coated with collagen for the adipocytes culture, and with mineral apatite added for osteoblasts culture. These beads were cultivated in a bioreactor simulating microgravity (Rotating Wall Vessel, RWV, NASA). With strontium, this RWV culture promoted osteogenesis and limited adipogenesis, validating the use of strontium as a repressor of the microgravity deleterious effects on bone. We have shown that this effect can be explained first by the stimulation of both GTPases RhoA and Rac1 activities, and secondly by the induction of the matrix-bound VEGF isoform in osteoblasts. In contrast, in adipocytes, both soluble and matrix-bound VEGF isoforms were inhibited. Moreover, strontium induced Flt-1 receptor expression, which would promote osteogenesis. All these data allowed us to better understand the RhoA and Rac1 kinetics during osteoblastogenesis and adipogenesis, and the important role of VEGF signaling pathways and oxidative status in directing multipotent cells differentiation. Strontium was found to be a good osteogenic inductor whose core applications can bring new ways of use

Full textEnzymatic membrane reactors combine several desirable characteristics in a bioprocess, such as high productivity, reproducibility, easy control and automation, continuous operation, efficient separation of biocatalyst, substrate and products, and the use of enzymes without immobilization. This work is part of the development and optimization of a bioprocess using an enzymatic reactor which utilizes a membrane reactor for the enzymatic hydrolysis of sucrose in a solution of fructose and glucose, containing the enzyme invertase. The influence of some operational and reaction variables on the performance of the membrane reactor was studied. The bioreactor consisted of a 50 mL-stirred tank where intact cells of Saccharomyces cerevisiae, containing invertase in the cell wall, are retained inside the reactor by a microfiltration membrane (Øpore 0.45µm). The flat sheet membrane is fixed at the bottom of the device. The reactor configuration is similar to a continuous stirred tank reactor (CSTR). Initially, the influence of sucrose and enzyme concentration was evaluated through a series of experiments in order to determine the suitable levels of these variables. Sucrose was set to 500 mM and enzyme set to 1 mg/mL. This allowed the work to continue by means of experimental factorial designs. It was utilized a 23 full experimental design followed by a 2nd order statistical design and, the surface response methodology in order to evaluate the influence of volume feeding rate of the substrate, temperature and pH on fructose productivity and sucrose conversion. The values were obtained during the reactor operation. The average operation time was trom 8 to 9 hours for all evaluated conditions. From the statistical analysis, it was concluded that the linear and quadratic effects of temperature and flow rate on the results were the most significant with 95% of confidence. The optimum conditions found for this bioprocess were volume feeding rate between 0.4 and 1.0 mL/min and temperature of 51°C. The degree of conversion of sucrose obtained experimentally was 95%, in the following experimental conditions: cell concentration of 1mg/mL, temperature of 51°C, pH 5.5; sucrose concentration of 500 mM and feeding rate of 1.0 mL/min. For this operational condition it was obtained a productivity of about 0.6 mmol fructose/h.mg invertase. The deviation between the predicted values by the statistical model and the experimental data was 3%. Based on the results obtained in this work, it can be concluded that this conception of bioreactor is efficient for the bioconversion of sucrose and, a continuous membrane reactor process is very promising for the development of this kind of enzymatic process.

Full textTo date, limited information has been published on textile wastewater treatment, for re-use, in South Africa (SA), with treatment processes focusing on conventional wastewater treatment methods. A large contributor to the contamination of water within textile industries is from dyehouse processes. A major concern in textile wastewater treatment is the release of azo dyes and their metabolites, some of which are carcinogenic and mutanogenic, into the environment since they are xenobiotic and aerobically recalcitrant to biodegradation. A necessity therefore exists to find an effective treatment method capable of removing both the strong colour and the toxic organic compounds from textile wastewater. Membrane bioreactors (MBRs) are favoured when treating high-strength wastewater, since the membrane area is determined by the hydraulic throughput and not the biological load; no sludge is wasted and all bacteria are retained within the reactor, including specific bacteria capable of degrading the toxic, non-biodegradable constituents present in textile wastewater. MBR systems, using various configurations have been utilised extensively in the rest of the world to treat textile wastewater at both lab and pilot-scale. This DTech project formed part of a collaborative Water Research Commission (WRC) funded project K5/1900 - Pilot application of a dual-stage membrane bioreactor (dsMBR) for industrial wastewater treatment. The main purpose of this study was the on-site evaluation of a pilot-scale dsMBR incorporating two ultrafiltration (UF) sidestream membrane modules for the treatment, recovery and re-use of textile wastewater. The objectives of this project were to determine the treatment efficiency of the system; to evaluate the degree of colour removal from the textile wastewater; to improve residual colour removal within the system using treatment processes, such as NF and RO, as well as to propose a design and cost for a full-scale plant. A textile industry located in Bellville, Western Cape, was chosen as the industrial partner for the on-site evaluation of a semi-automated pilot wastewater treatment MBR plant using two 5.1 m2 Norit X-flow AirliftTM membrane modules. Since the wastewater treatment system was located on the premises, real continuously changing industrial wastewater was being treated. The industrial textile wastewater was treated in a series of tanks: 1) an anaerobic tank, which cleaved the azo bonds of the reactive dyes; 2) an anoxic tank containing reduced amounts of dissolved oxygen, in which denitrification occurred; and 3) an aerobic tank, in which i) nitrification, as well as ii) mineralisation of the aromatic amines occurred. The UF-membrane modules would account for the removal of any organic material. The wastewater stream was characterised by a chemical oxygen demand (COD) range of between 45 to 2,820 mg/L and an average biological oxygen demand (BOD) of 192.5 mg/L. The dsMBR achieved an average COD reduction of 75% with a maximum of 97% over the 220 day test period. The COD concentration obtained after dsMBR treatment averaged at 191 mg/L, which was well within the City of Cape Town industrial wastewater discharge standard. The average reduction in turbidity and TSS was 94% and 19.6%, respectively, during the UF-MBR stage of the system. Subsequent treatment of the UF permeate with nanofiltration (NF) for 4 days, alternated with reverse osmosis (RO) for 14 days removed both the residual colour and salt present in the UF permeate. A consistent reduction in the colour of the incoming wastewater was evident. The colour in the wastewater was reduced from an average of 659 ADMI units to ~12 ADMI units in the NF permeate, a lower American dye manufacturing index (ADMI) (i.e. method of colour representation) compared to the potable water (~17 ADMI units) utilised by the industrial partner in their dyeing processes. The colour was reduced from an average of 659 to ~20 ADMI units in the RO permeate, a lower ADMI and therefore colour when compared to the potable water. An average conductivity rejection of 91% was achieved with conductivity being reduced from an average of 7,700 to 693 μS/cm and the TDS reduced from an average of 5,700 to 473 mg/L, which facilitated an average TDS rejection of 92%. Based on the composition of the UF permeate fed to the RO membrane a maximum removal of 98.7% was achieved for both conductivity and total dissolved solids (TDS). The proposed full-scale plant would incorporate a UF-MBR system, followed by NF, RO, flocculation and a filter press. Therefore, the two waste products produced during operation of the proposed full-scale plant, would be the solid filter cakes and the liquid filtrate from the filter press. Implementing the proposed full-scale plant it would cost the industrial partner an operating cost of ZAR 113.85 and ZAR 3,415.49 to treat 97.1 m3 and 2,913 m3 of textile wastewater, respectively, per day and per month. This results in an annual saving of ZAR 845,848 on potable water expenses. This research, would provide SA textile industries, with an option to: 1) reduce their water consumption, thereby utilising less of a valuable decreasing commodity; 2) meet the SA government discharge standards and reduce their discharge costs; 3) reduce their carbon footprint (i.e. reduce their impact on the environment) by re-using their treated wastewater and therefore using less water from the municipality; and 4) decrease their annual expenditure on water, since the treated wastewater would be available for re-use.

Full textCertain fungi have been shown to excrete extracellular enzymes, including peroxidases, laccases, etc. These enzymes are useful for bioremediation of aromatic pollutants present in industrial effluents (Leukes, 1999; Navotny et aI, 1999). Leukes (1999) made recent significant development in the form of a capillary membrane gradostat (fungal) bioreactor that offers optimal conditions for the production of these enzymes in high concentrations. This system also offers the possibility for the polluted effluent to be treated directly in the bioreactor. Some operating problems relating to continuous production of the enzymes and scale-up of the capillary modules, were, however, indentified. In an attempt to solve the above-mentioned identified problems the research group at Peninsula Technikon considered a number of alternative bioreactor configurations. A pulsed packed bed bioreactor concept suggested by Moreira et at. (1997) was selected for further study. Their reactor used polyurethane pellets as the support medium for the fungal biofilm and relied upon pulsing of the oxygen supply and recycle of nutrient solution in order to control biomass accumulation. These authors reported accumulation due to the recycle of proteases that were believed to destroy the desired ligninases. We experimented with a similar concept without recycle to avoid backrnixing and thereby overcome protease accumulation. In our work, a maximum enzyme productivity of 456 Units.L1day·1 was attained. Since this was significantly greater than the maximum reported by Moreira et aI, 1997 (202 Units.L-1day-I) it appeared that the elimination of recycle had significant benefits. In addition to eliminating recycle we also used a length / diameter (L / D) ratio of 14: 1 (compared with 2.5: 1 used by Moreira et aI, 1997) in order to further reduce backrnixing. Residence time distributions were investigated to gain insight into mechanisms of dispersion in the reactor. It was found that the pulsed packed bed concept presented problems with regard to blockage by excess biomass. This led us to consider the advantages of a fluidized bed using resin beads. Accordingly, growth of fungi on resin beads in shake flasks was investigated with favorable results. An experimental program is proposed to further investigate the fluidized bed concept with a view to extending the operation time of the bioreactor. From our literature survey to date, packed bed fungal bioreactors are still the best reactor configuration for continuous production ofligninolytic enzymes. An interesting study of the application of laccases to the degradation of naphthalene and MTBE is described in an addendum to this thesis.

Full textMicrobial fuel cell (MFC) has been considered as a renewable energy source which uses bacteria to convert chemical energy into electricity. Since the anode, as the electron acceptor for the electroactive bacteria, directly interacts with microorganisms, the selection of high performance anode materials is of crucial importance in the design of a MFC. Recently, graphene has been considered as the intriguing material, attracting strong scientific and technological interest with great application potentials in various fields, such as lithium ion batteries, solar cells and electrochemical super-capacitors, for its unique nanostructure and extraordinary properties. Therefore, surface modification using reduced graphene oxide has been investigated for the construction of anodes. An abiotic cathode has also been investigated since it often has a kinetic limitation regarding the oxygen reduction reaction. The potential of the use of organometallics complexes, and more particularly nickel phthalocyanines (poly-NiTSPc), has been studied and applied to the fabrication of cathodes for biofuel cells applications. Thereby, a dual chamber hybrid MFC has been constructed combining a reduced graphene oxide modified bioanode with a chemical poly-NiTSPc modified carbon felt. This MFC uses compost garden leachate, as source of microorganisms, for the growth of an electroactive biofilm onto the anode and presents an excellent lifetime. Indeed, graphene allowed to obtain a power density stable for 40 fays (24.8 mW/m² with pure oxygen). When the modified carbon felt was used as cathode, the power densities obtained were 7.5 higher than the use of platinum cathode. Furthermore, a new design of a dual chamber MFC has been built up in order to work with a constant flow, to supply continuously substrates to the biofilm formed onto the anode from a pure strain, Pseudomonas aeruginosa, and to avoid to work in a batch as it is usually done. The interest of this configuration is to prevent any current loss due to a lack in supply of substrates. Using this bioreactor as a MFC, different parameters have been explored such as the feed rate and the glucose consumption in the anodic compartment, the evolution of the pH as well as the biomass between the entrance and the exit of the chamber. A first study of the correlation between all these parameters has been proposed
