Humic acid promotes arsenopyrite bio-oxidation and arsenic immobilization

Journal of Hazardous Materials, 2020
The bio-oxidative dissolution of arsenopyrite, the most severe arsenic contamination source, can be mediated by organic substances, but pertinent studies on this subject are scarce. In this study, the bio-oxidative dissolution of arsenopyrite by Sulfobacillus thermosulfidooxidans and arsenic immobilization were evaluated in the presence of humic acid ...

Bio-oxidation of galena particles by Acidithiobacillus ferrooxidans

Particuology, 2008
Abstract This paper deals with the bio-oxidation of galena particles (−80 meshes) using Acidithiobacillus ferrooxidans and compares it with Fe3+ oxidation. Experimental results show that, at least, 0.00197 mol galena was leached from 100 mL pulp (density of 3.8%) with 39 days’ bio-oxidation, as compared to 0.00329 mol galena by Fe3+ with 9 days ...

Enhancement of bio-oxidation of refractory arsenopyritic gold ore by adding pyrolusite in bioleaching system

open access: yesTransactions of Nonferrous Metals Society of China, 2016
Pyrolusite was added in the bioleaching process to enhance the bio-oxidation process. Bioleaching tests at different dosages of pyrolusite ore, pH and inoculation amounts of Acidithiobacillus ferrooxidans were studied.

Non-Hydrolyzable Plastics – An Interdisciplinary Look at Plastic Bio-Oxidation

Trends in Biotechnology, 2021
Enzymatic plastic conversion has emerged recently as a potential adjunct and alternative to conventional plastic waste management technology. Publicity over progress in the enzymatic degradation of polyesters largely neglects that the majority of commercial plastics, including polyethylene, polypropylene, polystyrene and polyvinyl chloride, are still ...
