Evaluation of microbial diversity of the microbial mat from the extremely acidic Lake Robule (Bor, Serbia) [PDF]

open access: yesBotanica Serbica, 2017
Extremely acidic environments are frequently formed in areas impacted by mining activities, and Lake Robule is such an ecosystem. Although an extreme environment, Lake Robule is inhabited by acidophilic microorganisms. We investigated biodiversity of the

Insights into Adaptive Mechanisms of Extreme Acidophiles Based on Quorum Sensing/Quenching-Related Proteins

open access: yesmSystems, 2022
Quorum sensing (QS) is a unique mechanism for microorganisms to coordinate their activities through intercellular communication, including four main types of autoinducer-1 (AI-1, namely, N-acyl homoserine lactone [AHL]), AI-2, AI-3, and diffusible ...

Global Biogeographic Distribution Patterns of Thermoacidophilic Verrucomicrobia Methanotrophs Suggest Allopatric Evolution

open access: yesFrontiers in Microbiology, 2019
Thermoacidophilic methane-oxidizing Verrucomicrobia of the candidate genus Methylacidiphilum represent a bacterial taxon adapted to highly acidic (pH 1–4) and moderate temperature (∼65°C) methane-containing geothermal environments.

Shallow water marine sediment bacterial community shifts along a natural CO2 gradient in the Mediterranean Sea off Vulcano, Italy. [PDF]

open access: yes, 2014
The effects of increasing atmospheric CO(2) on ocean ecosystems are a major environmental concern, as rapid shoaling of the carbonate saturation horizon is exposing vast areas of marine sediments to corrosive waters worldwide. Natural CO(2) gradients off

Chromium (VI) Inhibition of Low pH Bioleaching of Limonitic Nickel-Cobalt Ore

open access: yesFrontiers in Microbiology, 2022
Limonitic layers of the regolith, which are often stockpiled as waste materials at laterite mines, commonly contain significant concentrations of valuable base metals, such as nickel, cobalt, and manganese.

Advances in bioleaching as a sustainable method for metal recovery from e-waste:A review [PDF]

open access: yes, 2019
Electronic waste (e-waste) accumulation on earth is a serious environmental challenge. The need for heavy metal recovery, together with the profitability of precious and base metals, are strong incentives for researchers to find a sustainable method for ...

Oxygen and ROS Delivery for Infected Wound Healing and Future Prospects

open access: yesAdvanced Healthcare Materials, EarlyView.
Bacterial infection is a major driver of delayed wound healing and postsurgical readmissions; with rising antibiotic resistance, solid peroxide–releasing biomaterials offer sustained delivery of ROS/O2 for antimicrobial control and microenvironmental modulation.

Characterization and genomic analysis of two novel psychrotolerant Acidithiobacillus ferrooxidans strains from polar and subpolar environments

open access: yesFrontiers in Microbiology, 2022
The bioleaching process is carried out by aerobic acidophilic iron-oxidizing bacteria that are mainly mesophilic or moderately thermophilic. However, many mining sites are located in areas where the mean temperature is lower than the optimal growth ...
