Extraction of carotenoids from Chlorella vulgaris using green solvents and syngas production from residual biomass

Christof Holliger, Christian Ludwig, Shivom Sharma, Jean-Paul Schwitzguebel, Dominik Refardt

A combined process for carotenoids extraction and efficient bioenergy recovery from the wet microalgae biomass is proposed. High added-value products could thus be extracted prior a hydrothermal gasification of the algal biomass into synthetic natural gas. ...
