Leptospirillum ferriphilum Sp-Cl is a Gram negative, thermotolerant, curved, rod-shaped bacterium, isolated from an industrial bioleaching operation in northern Chile, where chalcocite is the major copper mineral and copper hydroxychloride atacamite is present in variable proportions in the ore. This strain has unique features as compared to the other members of the species, namely resistance to elevated concentrations of chloride, sulfate and metals. Basic microbiological features and genomic properties of this biotechnologically relevant strain are described in this work. The 2,475,669 bp draft genome is arranged into 74 scaffolds of 74 contigs. A total of 48 RNA genes and 2,834 protein coding genes were predicted from its annotation; 55 % of these were assigned a putative function. Release of the genome sequence of this strain will provide further understanding of the mechanisms used by acidophilic bacteria to endure high osmotic stress and high chloride levels and of the role of chloride-tolerant iron-oxidizers in industrial bioleaching operations.

is a Gram-negative bacterium that thrives in extreme acidic conditions. It has emerged as a key player in biomining and bioleaching technologies thanks to its unique ability to mobilize a wide spectrum of elements, such as Li, P, V, Cr, Fe, Ni, Cu, Zn, Ga, As, Mo, W, Pb, U, and its role in ferrous iron oxidation and reduction. catalyzes the extraction of elements by generating iron (III) ions in oxic conditions, which are able to react with metal sulfides.

Article Synopsis
  • The study investigates the extraction of nickel and other elements from arsenic-rich ores through oxidative bioleaching using different types of bacteria.
  • Mesophilic bacteria showed over 99% nickel recovery within 28 days for high-grade ores, significantly outperforming chemical methods, which only achieved roughly 26.1%.
  • Additionally, kinetic modeling indicated that the bioleaching process varied based on ore grade, demonstrating the effectiveness of using mixed bacterial cultures for efficiently extracting valuable metals from these challenging ores.
