Biosorption of Reactive Dyes by Novel Bacterium Leclercia adecarboxylata: Complete Removal of Reactive Black 5 and Molecular Insights Into the Adsorption Mechanism

Water Environment Research, Volume 97, Issue 6, June 2025.
Reactive Black 5 was biosorbed by Leclercia adecarboxylata, highlighting removal and adsorption mechanism. ABSTRACT Leclercia adecarboxylata isolated from the Düden Waterfall (Turkey) was utilized as a biosorbent for the removal of Reactive Black 5 (RB5), Setazol Blue BRF‐X (BRF‐X), Setazol Navy Blue SBG (SNB), and Setazol Turquoise Blue G (STBG).

Cement Composites Biodeterioration by Acidithiobacillus Thiooxidans

WSEAS TRANSACTIONS ON ENVIRONMENT AND DEVELOPMENT
The focus of this work was to study the biodeterioration of special cement composites by sulfur-oxidizing bacteria Acidithiobacillus thiooxidans. The laboratory prepared cement composites that contained the selected additives - silica fume (a secondary raw material) and zeolite (a natural raw material), as partial replacements for the binder. The tests
