PROCESS FOR FORMING CARBON-NEGATIVE MINERALS USING BIOMINERALIZING MACROORGANISMS

Abstract

TITLE: PROCESS FOR FORMING CARBON-NEGATIVE MINERALS USING BIOMINERALIZING MACROORGANISMS The invention relates to a process for producing a carbon-negative biomineralized macroorganism, the process comprising the following steps: supplying a biomineralizing macroorganism comprising an organic phase and a mineral phase containing calcium carbonate; culturing, under an atmosphere comprising carbon dioxide, the biomineralizing macroorganism in a culture solution comprising salt water having a salinity level between 3 and 260 PSU and an alkalinity level between 1 mmol / L and 200 mmol / L; culturing during which the biomineralizing macroorganism produces calcium carbonate crystals; adding an alkaline charge to the culture solution to ensure the growth of the calcium carbonate crystals of the biomineralizing macroorganism during its biomineralization.harvesting at least part of the biomineralized macroorganism when one of its average dimensions is greater than or equal to 1 cm.
