Deciphering microbial communities involved in marine steel corrosion using high‐throughput amplicon sequencing

Environmental Microbiology Reports, Volume 16, Issue 4, August 2024.
Aggressive forms of intertidal steel corrosion are shown to involve complex microbial consortia including sulfate‐reducing, sulfide‐oxidizing and iron‐oxidizing bacteria along with others including electroactive microbes. Statistical analysis shows the populations are derived from local bed sediment, indicating sediment anoxia as a risk factor for ...

Small‐scale and scale‐up bioleaching of Li, Co, Ni and Mn from spent lithium‐ion batteries

Journal of Chemical Technology &Biotechnology, Volume 99, Issue 5, Page 1069-1082, May 2024.
Abstract BACKGROUND A bioleaching process could offer the advantage of higher metal recovery in a sustainable manner even from lithium‐ion battery (LIB) samples with very low metal concentrations. In recent years, there has been a significant increase in the use of secondary resources such as LIBs for various purposes including transportation, large ...

Biosynthesized Metallic and Bimetallic Nanoparticles as Effective Biocides for Plant Protection: Plausible Mechanisms and Challenges

Journal of Chemistry, Volume 2024, Issue 1, 2024.
The use of biosynthesized metallic and bimetallic nanoparticles (NPs) as biocides for plant protection has gained significant attention in recent years due to their potential for sustainable and ecofriendly crop protection. In this review article, we discussed the biosynthesis of metallic and bimetallic NPs using various biological sources such as ...

Synthetically Modified Tara and Oak Gall Nut Tannin‐Based Corrosion Inhibitors for Combating the Corrosive Influence of Acidithiobacillus thiooxidans on Mild Steel

International Journal of Corrosion, Volume 2024, Issue 1, 2024.
Natural tara and oak gall nut tannins, which lack corrosion inhibitive properties, were modified using gum arabic and tested against microbial corrosion induced by Acidithiobacillus thiooxidans under isothermal condition (28°C). Mild steel coated with the modified tannins was exposed to the causative under aerobic and anaerobic conditions. Based on the
