Biotechnological production of biogrout from iron ore and ...

The hydraulic conductivity of sand after treatment with the iron‐based biogrout decreased from 7 × 10⁻⁴ m s⁻¹ to 1.4 × 10⁻⁶ m s⁻¹ with 4.5% (w/w) content of iron in biocemented sand. CONCLUSIONS: Low cost iron‐based biogrout can be produced using anaerobic fermentation of cellulose and bioreduction of hematite iron ore.
