Effective removal of the rotifer Brachionus calyciflorus from a Chlorella vulgaris microalgal culture by homogeneous solar photo-Fenton at neutral pH

Christian Ludwig, Horst Pick, Stefanos Giannakis, Adrian Pulgarin, Jiahua Chen, Dominik Refardt, Jérémie Decker

In this study, a citrate-modified photo-Fenton process was successfully applied to decontaminate a Chlorella vulgaris microalgae culture spiked with the rotifer Brachionus calyciflorus (5 individuals mL−1). The applied treatment (1 mg L−1 Fe2+, 20 mg L−1 H ...

Enhancing Algae Biomass Production by Using Dye-Sensitized Solar Cells as Filters

Mohammad Khaja Nazeeruddin, Christian Ludwig, Shivom Sharma, Peng Qin

One of the most promising options for decreasing the costs of microalgae production is enhancing the production and reducing the energy demand of the culturing systems and the high surface area requirements. Because microalgae growth requires only specific ...

A novel proposition for a citrate-modified photo-Fenton process against bacterial contamination of microalgae cultures

César Pulgarin, Christian Ludwig, Stefanos Giannakis, Adrian Pulgarin, Dominik Refardt

This study reports the first attempt of a citrate-modified photo-Fenton (PF) application at near-neutral pH (7.5–8.5, tap water) to disinfect Escherichia coli (as model bacterium), in Chlorella vulgaris cultures. The conditions are aimed towards bacterial ...

Co-culture of microalgae-activated sludge for wastewater treatment and biomass production: Exploring their role under different inoculation ratios

Florian Frédéric Vincent Breider

In this study, mixed culture (microalgae:activated sludge) of a photobioreactor (PBR) were investigated at different inoculation ratios (1:0, 9:1, 3:1, 1:1, 0:1 wt/wt). This work was not only to determine the optimal ratio for pollutant remediation and bio ...

Production of Algae for Biomaterials and Bioenergy: Closing the Nutrient Cycle and Enhancing the Light Utilisation Efficiency

Eya Nicodeme

Microalgae are small organisms that live in water and use solar energy or artificial light to grow. They are emerging to be one of the most promising long-term, sustainable sources of biomass for fuel, food, feed, and other high valuable co-products. Like ...

Demographic stochasticity and resource autocorrelation control biological invasions in heterogeneous landscapes

Andrea Rinaldo, Andrea Giometto, Florian Altermatt

Mounting theoretical evidence suggests that demographic stochasticity, environmental heterogeneity and biased movement of organisms individually affect the dynamics of biological invasions and range expansions. Studies of species spread in heterogeneous la ...

Supercritical water gasification of effluents from composted human excreta and recycling of the aqueous phases for microalgae cultivation

Dorian Tosi Robinson

Effluents from composted human excreta were sampled and characterized. Results show a constancy in the characteristics and nutrient content of these effluents. Then, these effluents were treated with supercritical water gasification, producing hydrogen ric ...
