Purification of Cellulose and Chitin Polymers and Other Value-Added Products from the Microalga Chlorella vulgaris Using a Green Biorefinery Process

Horst Pick, Christian Ludwig, Enio Daniel Zanchetta, Eya Nicodeme

Microalgae produce renewable biomass at high efficiency by using photosynthesis to capture the greenhouse gas CO2 from the atmosphere and releasing O2. Chlorella vulgaris is one of the most frequently cultivated unicellular green microalgae of commercial r ...

Abiotic stress approaches for enhancing cellulose and chitin production in Chlorella vulgaris

Horst Pick, Christian Ludwig, Enio Daniel Zanchetta, Eya Nicodeme

Several lines of evidence point to the presence of both, cellulose and chitin as structural constituents of the Chlorella vulgaris cell wall. These biopolymers are favourable building blocks for many sustainable industrial applications for instance as bioc ...

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

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

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 combined hydrothermal gasification - solid oxide fuel cell system for sustainable production of algal biomass and energy

Jan Van Herle, François Maréchal, Christian Ludwig, Hossein Madi, Eya Nicodeme, Shivom Sharma

Hydrothermal gasification (HTG) is a promising technology that allows the recovery of nutrients from wet biomass with simultaneous production of an energy-rich gas. In this work, wastewater effluent (leachate) obtained from a composter sanitary system oper ...
