Summary: This study investigated the combined effect of silver and pyrite on chalcopyrite bio-dissolution, showing that their presence increased the release of copper. The promotion effect of silver and pyrite on chalcopyrite bio-dissolution was mainly attributed to the increase of ferric ions in solution and the reduction of passivation layer on chalcopyrite surface.

Summary: Recycling valuable metals from spent lithium-ion batteries using an ultrasonic-assisted bioleaching process was studied. The results showed that metal extraction and bioleaching time were enhanced by ultrasonication, with 19% Co, 50% Mn, 34% Ni, and 67% Li extracted after 12 hours. The study also found that ultrasound with a power of 203.5 W for 10 minutes daily promoted the growth of Acidithiobacillus ferrooxidans.

Summary: Acid mine drainage (AMD) with low pH and high concentrations of sulfates and heavy metals is a major source of environmental pollution. This study proposes a novel treatment system for AMD using a combination of bio-oxidation and carbonate rock neutralization. The results showed that by adding carbonate rocks, the efficiency of Fe2+ oxidation and total iron removal increased significantly compared to the control group. The addition of carbonate rocks also regulated the acidic environment and facilitated the formation of schwertmannite, providing favorable conditions for bacterial attachment. Acidithiobacillus and Leptospirillum were identified as the dominant bacteria in the biological oxidation stage. These findings provide valuable insights for the development of a combined treatment method for AMD using biological oxidation and carbonate rock neutralization.

Summary: This study investigates the self-inhibition mechanism of ATP hydrolysis in A. baumannii F-1-ATPase (AbF(1)-ATPase) by generating and purifying a recombinant AbF(1)-ATPase and analyzing its structure. The results reveal that the C-terminal domain of subunit epsilon (Ab epsilon) plays a major role in regulating ATP hydrolysis in AbF(1)-ATPase. The findings have important implications for understanding the regulation of ATP hydrolysis.

Summary: This study compared two eco-friendly leaching methods, chemical leaching and bioleaching, for the recovery of Li, Ni, Co, and Mn from waste lithium-ion batteries. The results showed that complete leaching of the target metals was achieved using 6.86M levulinic acid under optimal conditions in chemical leaching. In bioleaching, pretreatment of the waste batteries significantly improved the extraction efficiency. The comparison of these two methods provides technical details for further cost and environmental impact analysis.

Summary: The study compared the tolerance and response of Leptospirillum ferriphilum and Acidithiobacillus ferrooxidans to oxidative stress, with L. ferriphilum showing higher cell density, lower oxidative damage, and higher activity levels of antioxidative proteins. This suggests that L. ferriphilum has a greater capacity to respond to oxidative stress and manage redox homeostasis.

Summary: This review introduces the techniques and mechanisms of bacteria immobilization on biochar, as well as its applications in bioremediation and agriculture. The immobilization characteristics of biochar depend on pyrolysis methods, raw materials, and properties of biochar. Scanning electron microscope and colony forming unit analysis are commonly used to verify the immobilization efficiency. Applying biochar-immobilized bacteria can improve soil quality, plant growth, and crop yield.
