Abstract: Rapid depressurization and warming during recovery can trigger stress in deep-sea microbes and accelerate RNA degradation. We developed a remotely operated vehicle (ROV)-oriented multi-sequence microbial sampler for 2000 m sampling (20 MPa, 2 &amp;deg;C) that integrates in situ filtration with immediate RNAlater injection (an RNA stabilization reagent), collecting up to 12 samples per dive. A Dirichlet sampling&amp;ndash;B-spline&amp;ndash;SVM framework was used to optimize the cam p[...]


Our summary: A multi-sequence microbial sampler was developed for deep-sea environments, integrating in situ filtration with RNAlater injection. The design optimizes actuation under constraints, reducing torque requirements significantly. Computational fluid dynamics modeling predicts membrane clogging and RNAlater displacement dynamics during operation.

Assessing the Potential of Heterotrophic Bioleaching to Extract Metals from Mafic Tailings

Published on 2026-02-02 by Kamalpreet Kaur Brar, Avi Du Preez, Nancy N. Perreault @MDPI

Abstract: Mafic mine tailings are highly resistant to bioleaching due to their silicate-rich composition, low sulfide content, and strong buffering capacity. This study aimed to assess the potential use of heterotrophic bioleaching to promote the release of metals from mafic tailings by evaluating the organic acid production and leaching capabilities of indigenous bacterial isolates and a known lactic acid producer, Lactiplantibacillus plantarum ATCC 8014. Indigenous acid-producing heterotrophic bacteria [...]


Our summary: This study evaluates heterotrophic bioleaching for metal extraction from mafic tailings. Indigenous bacteria and Lactiplantibacillus plantarum produced significant organic acids, enhancing metal solubilization. Zinc was efficiently leached, indicating selective mobilization potential despite limitations for refractory metals.
