Red Mud as a Secondary Source of Scarce Metals - Recovery using Red Microalgae

Náhlík V., Čížková M., Singh A., Bišová K., Mezricky D., Rucki M., (Corresponding) Vítová M.

Topic:

Environmental biotechnology and bioenergy

Red mud is a by-product of the production of alumina from bauxite ore. Less than 2% of the red mud produced is currently being reused. The red mud contains a number of residual elements, some at a considerable concentration. The red microalga Galdieria sulphuraria was used to test the accumulation...Read more

Prohibition of the cultivation of Genetically Modified Organisms in Cyprus through the attitudes of stakeholders

(Corresponding) Varnava Tello A., Zorpas A.

Topic:

Environmental biotechnology and bioenergy

The biotechnology industry has always been held under close public scrutiny and even more so whenever new technology or findings are released. Opponents of genetically modified organisms (GMOs) support that scientific risk assessments are not sufficient to address potential long-term hazards for...Read more

Production and characterization of microalgal biomass from dairy wastewater

Iliopoulou A., Zkeri E., Panara A., Dasenaki M., Aloupi M., Fountoulakis M., Thomaidis N., (Corresponding) Stasinakis A.

Topic:

Environmental biotechnology and bioenergy

During the last decade, a large scientific effort has been directed towards the cultivation of microalgae in dairy wastewater. Among different microalgal species, Chlorella sorokiniana is a small, fast-growing, robust microalgae that can be grown under mixotrophic conditions. In the current study,...Read more

Condensate originating from household food waste as a substrate for Microbial Fuel Cells

Kamperidis T., Pandis P., Vlachaki E., (Corresponding) Tremouli A., Lyberatos G.

Topic:

Environmental biotechnology and bioenergy

A microbial fuel cell (MFC) is a bioreactor that converts the chemical energy of the bonds of organic compounds to electrical energy, through the catalytic reactions of microorganisms. Under anaerobic conditions various substrates have been examined using MFC technology. This study examines the...Read more

Hydrogen production in a microbial electrolysis cell: the influence of operational parameters

(Corresponding) ANTONOPOULOU G., APOSTOLOPOULOS I., BAMPOS G., BEBELIS S., LYBERATOS G.

Topic:

Environmental biotechnology and bioenergy

In the present study two identical two-chamber microbial electrolysis cells (MECs), fed with an acetate synthetic medium, were used for hydrogen production, using different anodic materials, i.e. commercial carbon fiber paper (CP) and graphite granules (GG). The effects of the applied voltage (i.e...Read more

Novel hybrid technology for the sustainable development of the circular economy in urban agriculture

(Corresponding) Giaquinto D., Senatore V., Oliva G., Nesticò A., Hasan S., Zarra T., Belgiorno V., Naddeo V.

Topic:

Environmental biotechnology and bioenergy

Climate change and environmental pollution are just some of the main challenges to be addressed. A number of actions have been taken, in particular the circular economy has proved to be among the most effective in overcoming the traditional approach of the linear economy. Circular economy means not...Read more

The effect of catalysts MnO2, activated carbon and fly ash on the performance of single-chamber Microbial Fuel Cells

(Corresponding) Tremouli A., Kamperidis T., Pandis P., Stathopoulos V., Ieropoulos I., Argirusis C., Lyberatos G.

Topic:

Environmental biotechnology and bioenergy

Microbial fuel cells (MFC) are bioelectrochemical systems that convert the chemical energy contained in waste to electricity, using bacteria as catalysts. In order to boost the power output of MFCs, various approaches are feasible. This study examines the effect of using MnO2, activated carbon and...Read more

Biogas upgrade via ex-situ technologies

Spyridonidis A., Vasiliadou I., (Corresponding) Stamatelatou K.

Topic:

Environmental biotechnology and bioenergy

The biological upgrade of biogas to biomethane (CH4 > 90%) is a popular emerging technology, since the produced CO2 is not removed but is converted to biomethane using hydrogen (H2). The initial aim of the present study is the acclimatization of a microbial population derived from a typical...Read more
