Bioleaching of Indonesian Galena Concentrate With an Iron- and Sulfur-Oxidizing Mixotrophic Bacterium at Room Temperature

Frontiers in Microbiology, 2020
Biohydrometallurgy is believed to be a promising future study field for the recovery of lead (Pb) from ores/concentrates since the pyrometallurgical/hydrometallurgical processes have been largely applied to recover Pb to date, which operates at high ...

Nutrient optimization in bioleaching: are we overdosing?

Frontiers in Microbiology
The general trend in biomining (i.e., bioleaching and biooxidation) is the use of media with high concentrations of the nutrients (nitrogen as ammonium, phosphorous as phosphate, and K), which are considered to be essential for microbial growth.

Sustainable Pretreatment of Food Waste for Enhanced Bioethanol Production and Improved Waste Management: A Review

Food Science &Nutrition, Volume 14, Issue 2, February 2026.
The graphical abstract illustrates the conversion of food waste biomass into bioethanol through integrated pretreatment strategies. Physical (mechanical, thermal, sonication), chemical (alkali, acidic, oxidative/ROS), and biological (fungal, bacterial, enzymatic) pretreatments enhance biomass breakdown.

Use of large pieces of printed circuit boards for bioleaching to avoid ‘precipitate contamination problem’ and to simplify overall metal recovery

MethodsX, 2014
Very recently bioleaching has been used for removing metals from electronic waste. Most of the research has been targeted to using pulverized PCBs for bioleaching where precipitate formed during bioleaching contaminates the pulverized PCB sample and ...

BIOLEACHING FOR THE RECOVERY OF METALS PEMISAHAN UNSUR LOGAM DENGAN BIOLEACHING

Buletin Sumber Daya Geologi, 2015
A simple laboratory experiment has been conducted in order to demonstrate the ability of bacteria to leach the metal elements from insoluble ores or solid substrates. The experiment was conducted in a leaching column that was set up using 5 cc syringe that contained 1 cc of glass wool and 3.5cc of mine tailings.
