Biotic vs. Abiotic Structured Mackinawite

Biotic

Example – Sulfate Reducing Microorganisms (SRM) produce sulfide, and when in the presence of iron, may react to form ferrors sulfide (FES).

Abiotic

Example – a FeS reagent that is manufactured or formulated to a specification in a chemical reactor and delivered to a remediation site.

Biotic and Abiotic Formation - Similarities

The first iron sulfide formed biotically is a reactive ferrous sulfide (FeS) mineral with a “mackinawite” structure. This is also the main ingredient in FerroBlack®.

Biotic and Abiotic Formation - Differences

Why “roll the dice” by assuming the in-situ conditions will be optimal for biotic FeS Formation?

Simply, Redox Solutions abiotically synthesized mackinawite structured iron sulfide products eliminate the unknown factors of biotic iron sulfide formation.
