Mineral carbonation is a prominent method for carbon sequestration. Atmospheric dioxide (CO2) trapped as mineral carbonate precipitates, which are geochemically, geologically, and thermodynamically stable. Carbonate rocks can originate from biogenic or abiogenic origin, whereby the former refers to breakdown of biofragments latter precipitation out water. Carbonates also be formed through biologically controlled mechanisms (BCMs), mediated (BMMs), induced (BIMs). Microbial (MCP) BMM occurring interaction organics (extracellular polymeric substances (EPS), cell wall, etc.) soluble cations facilitating indirect minerals. Microbially (MICP) BIM via different metabolic pathways. Enzyme-driven pathways (carbonic anhydrase (CA) and/or urease), specifically, promising high conversion calcium (CaCO3) precipitation, trapping large quantities gaseous CO2. These precipitates trap CO2 trapping, solubility formation aid in leakage reduction geologic Additional experimental research required assess feasibility MICP sequestration at scale long-term stability precipitates. Laboratory-scale evaluation provide preliminary data on preferable materials their capacity atmospheric versus injected
