Cultivation of Electrogens With Cost‐Effective Membrane‐Less Bioreactor Designs

Fuel Cells, Volume 26, Issue 3, June 2026.
ABSTRACT Rational improvements in bioreactor design for scaling up power generation in microbial fuel cells (MFCs) are discussed in this study. The potential of autoclavable MFCs for isolating electroactive bacteria that produce sustainable electricity is being investigated.

Unraveling Oral Dysbiosis: Microbial Complexity in Common Oral Diseases

MicrobiologyOpen, Volume 15, Issue 3, June 2026.
The oral microbiome undergoes dynamic establishment from birth, maturing into a resilient ecosystem. Perturbation of this homeostasis—driven by dietary, immunological, and anatomical factors—triggers dysbiosis, which underpins the pathogenesis of major oral diseases, including dental caries, periodontal disease, salivary gland disorders, oral mucosal ...

Fungal‐Bacterial Interactions in Polymicrobial Infections: Hidden Threats

MicrobiologyOpen, Volume 15, Issue 3, June 2026.
ABSTRACT Polymicrobial infections involving fungi and bacteria represent a major and increasingly recognized clinical challenge, in which interkingdom interactions significantly amplify disease severity, antimicrobial resistance, and treatment failure. Rather than passive co‐existence, fungal–bacterial communities form highly coordinated systems driven

Dissolution Kinetics of Complex Sulfides Using Acidophilic Microorganisms

MATERIALS TRANSACTIONS, 2010
Bioleaching studies were conducted to evaluate a complex sulfide concentrate using an acidophilic microorganism. The leaching kinetics were found to vary based on pulp density, Fe and pH. In addition, the leaching efficiency increased as the Fe(II) concentration increased up to 20 kgm 3 , after which it decreased due to an increase in iron ...

Osmotic Imbalance, Cytoplasm Acidification and Oxidative Stress Induction Support the High Toxicity of Chloride in Acidophilic Bacteria

Frontiers in Microbiology, 2019
In acidophilic microorganisms, anions like chloride have higher toxicity than their neutrophilic counterparts. In addition to the osmotic imbalance, chloride can also induce acidification of the cytoplasm.

Polyphasic Characterization of Acetobacter indonesiensis UNPADCC 01‐5 Isolated From a Traditional Fermented Food, Oncom Merah

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.
The polyphasic approach (morphology, physiology, biochemistry and genetics) was used to characterize Acetobacter indonesiensis strain UNPADCC 01‐5, which was isolated from oncom merah. The strain's potential as a culture for acidic fermentations and a biofunctional agent was supported by its adaptive characteristics, which included acid tolerance ...

Effects of elevated pressures on the activity of acidophilic bioleaching microorganisms

Biochemical Engineering Journal, 2019
This study reports effects of elevated pressures on the oxidation of a soluble ferrous iron and low-grade sulphidic ore as little is known about biological iron and sulphur oxidation under these conditions. Pressure effects were studied in a pressurised batch-operated stirred tank reactor using acidophilic enrichment cultures.

Reduction of Iron(III) Ions at Elevated Pressure by Acidophilic Microorganisms [PDF]

Solid State Phenomena, 2017
A composed mixed acidophilic, iron-oxidizing culture (FIGB) and a thermo-acidophilic enrichment culture (TK65) were used to evaluate microbial iron(III) reduction coupled to oxidation of reduced inorganic sulfur compounds (RISCs) under high pressure. Experiments were done in batch culture in high pressure vessels at 1 and 100 bar.
