Mineral Salt Medium (MSM) for extreme acidophilic microorganisms

open access: yesProtocol Exchange, 2015
Medium for growth of extreme acidophilic microorganisms. This medium does not contain trace elements. When not working on mineral, addition of trace element (TE) solution is necessary, see separate protocol.

Molecular Signatures of Peripheral and Central Dental Pulp Subpopulations in Response to Streptococcus mutans: A Bulk RNA‐Seq Analysis

open access: yesInternational Endodontic Journal, Volume 59, Issue 7, Page 1402-1415, July 2026.
ABSTRACT Aim The dental pulp is an immunologically active tissue that responds dynamically to cariogenic challenge. Peripheral pulp cells adjacent to dentine encounter bacterial stimuli earlier than cells located in the central pulp. To investigate signalling and immune interactions, this study profiled the transcriptomes of dentine‐adherent cells ...

Bacterial Oxidation and Reduction of Iron in the Processes of Creation and Treatment of Acid Mining Waters [PDF]

open access: yesActa Montanistica Slovaca, 2004
Acid mine drainages (AMDs) arise at the weathering of sulphidic minerals. The occurrence of acidic streams is commonly associated with the human mining activities.

Deep Caries Management: EFCD‐ESE‐ORCA S3‐Level Clinical Practice Guideline

open access: yesInternational Endodontic Journal, Volume 59, Issue 7, Page 1298-1315, July 2026.
ABSTRACT Objective To develop an evidence‐based S3‐level clinical practice guideline for the management of deep and extremely deep caries in vital permanent teeth. Methods An evidence‐based medical guideline based on systematically searched and appraised evidence as well as a structured consensus (S3‐level) was jointly developed by the European ...

Characteristics of an Iron-Reducing, Moderately Acidophilic Actinobacterium Isolated from Pyritic Mine Waste, and Its Potential Role in Mitigating Mineral Dissolution in Mineral Tailings Deposits

open access: yesMicroorganisms, 2020
Reactive pyritic mine tailings can be populated by chemolithotrophic prokaryotes that enhance the solubilities of many metals, though iron-reducing heterotrophic microorganisms can inhibit the environmental risk posed by tailings by promoting processes ...

SPECIFIC FEATURES OF NATIVE CHEMOLITHOTROPHIC MICROBIOTA WASTES PRODUCED BY ENERGY INDUSTRY [PDF]

open access: yesBiotechnologia Acta, 2015
The study's aims were to isolate and establish pure cultures of prevailing microorganisms from the aboriginal consortium in coal fly ash (FAAC), describe their physiology, biochemistry and practically-useful properties, and compare the efficiency of ...

Nature's Nanotech Warriors: The Role of Metalloproteins and Protein Cages for Environmental Remediation

open access: yesAdvanced Sustainable Systems, Volume 10, Issue 6, June 2026.
Cartoon representation of five major classes of metalloproteins and their brief mechanisms of bioremediation. The five classes include metallothioneins, metal‐precipitating enzymes, P.‐type ATPases, protein cages, and synthetic metalloproteins (de novo‐designed proteins/peptides for selective adsorption). These natural and engineered protein structures

High phylogenetic turnover magnifies evolutionary relatedness along bacterial primary succession

open access: yesEcology, Volume 107, Issue 6, June 2026.
Abstract Current models of microbial primary succession postulate that stochasticity dominates the early stages of soil community assembly, generating phylogenetically random patterns that are lost as abiotic and biotic filters gain relevance. We hypothesized that, under severe environmental stress, abiotic filters may override stochasticity from early

Microbial biominers: Sequential bioleaching and biouptake of metals from electronic scraps

open access: yesMicrobiologyOpen, 2022
Electronic scraps (e‐scraps) represent an attractive raw material to mine demanded metals, as well as rare earth elements (REEs). A sequential microbial‐mediated process developed in two steps was examined to recover multiple elements. First, we made use
