Removing cyanide by mixed culture at liquid media with variation in pH and cyanide concentration

MATEC Web of Conferences, 2018
This preliminary study aims to investigate removal efficiency of cyanide by mixed culture Thiobacillus sp. and Clostridium sp. in a liquid media stone mineral salt solution (SMSs) with controlled condition. This research variation were pH 5, 7, and 9 and

Bioleaching as an Eco‐Friendly Nano‐Factory for Sustainable Inorganic Waste Management: Current Advancements, Challenges, and Opportunities

ChemistryOpen, Volume 14, Issue 9, September 2025.
The review explores the latest updates and information about the global trends and hazards of e‐waste and also discusses the bioleaching of metals and nanoparticles from various inorganic wastes. It also focuses on the mechanistic pathway of the bioleaching process and computational aspects. Inorganic waste management and metal recovery technology pose

Diverse Cooccurring Metabolisms Support Sulfur and Methane Cycling in Wetland Surficial Sediments

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 9, September 2025.
Abstract The Prairie Pothole Region (PPR) of North America contains millions of small depressional wetlands with some of the highest methane (CH4) fluxes ever reported in terrestrial ecosystems. In saturated soils, two conventional paradigms are (a) methanogenesis is the final step in the redox ladder, occurring only after more thermodynamically ...

In Hyphomicrobium denitrificans Two Related Sulfane‐Sulfur Responsive Transcriptional Repressors Regulate Thiosulfate Oxidation and Have a Deep Impact on Nitrate Respiration and Anaerobic Biosyntheses

Molecular Microbiology, Volume 124, Issue 3, Page 204-220, September 2025.
In Hyphomicrobium denitrificans, the use of thiosulfate as a supplemental electron donor is regulated by two homologous sulfane‐sulfur responsive ArsR‐type transcriptional repressors, sHdrR and SoxR, that act cooperatively. Remarkably, the regulation by sHdrR/SoxR extends far beyond sulfur oxidation and deeply affects anaerobic metabolism, particularly
