Resumen de: WO2022202069A1

In an acquisition step of this method for culturing microalgae, a protein is obtained from microalgae cultured in a culture step. In a saccharification step, the protein obtained in the acquisition step is added as a saccharifying enzyme to a pressing residue that contains cellulose and that is obtained by pressing a biomass material, and the pressing residue is saccharified. In a fermentation step, a sugar obtained in the saccharification step and/or a sugar contained in pressed juice obtained by pressing the biomass material is fermented to produce a fermented product. In a culture step, carbon dioxide generated in the fermentation step is supplied to the microalgae.

Systems and methods for cultivating or accumulating climate-focused marine target products are described herein. The target product may be microalgae, macroalgae, plankton, marine bacteria or archaea, filter feeders (such as oysters or clams), or crustaceans either for the purpose of bioremediation, eventual cultivation or for sequestering carbon dioxide; or the target product may be direct chemical or biological accumulation of carbon or carbon containing organisms. The system is primarily a floating apparatus designed to hold the target product in a region of the water column and in a spatial region of the water where it will best accumulate target product mass. In some embodiments the system is designed to achieve eventual passive sinking (transformation from a floating to sinking apparatus) into the deep ocean. In some embodiments, the system is equipped with purpose-chosen sensors to instrument and quantify the various biological and mechanical processes occurring onboard.
