Effect of chloride salts on biodesulfurization process of a colombian coal

Revista Facultad de Ingeniería Universidad de Antioquia, 2013
A chloride salts medium was evaluated in biodesulfurization processes of a Colombian coal (2.34% total sulfur: 1.34% as pyritic, 0.90% as organic and 0.10% from sulfates), employing a consortium of Acidithiobacillus ferrooxidans and Acidithiobacillus ...

Microbial Deterioration Potential and Mitigation Strategies in Blended Cement Structures: A Review

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Microbial‐induced deterioration (MID) is a threat to the durability of cement‐based materials (CBMs) particularly in sewer and wastewater systems. Whereas blended cements incorporating supplementary cementitious materials (SCMs) offer environmental benefits such as reduced carbon (IV) oxide (CO2) emissions and enhanced mechanical performance, their ...
