Enhanced biofuel production from microalgae by adding CO2 to stimulate lipid biosynthesis (biodiesel) and by hydrothermal processing (syngas)

Christian Ludwig, Frédéric Vogel, Jean-Paul Schwitzguebel, Gabriela Anca Haiduc, David Pauli

Introduction: Microalgae cultures represent an attractive source of biomass for biofuel and chemicals production since they can have higher energy yields per area than conventional biomass crops and can be grown on marginal land using waste, saline, or bra ...
