A critical review of mineral–microbe interaction and co-evolution: mechanisms and applications

National Science Review, Год журнала: 2022, Номер 9(10)

Опубликована: Июль 4, 2022

Mineral–microbe interactions play important roles in environmental change, biogeochemical cycling of elements and formation ore deposits. Minerals provide both beneficial (physical chemical protection, nutrients, energy) detrimental (toxic substances oxidative pressure) effects to microbes, resulting mineral-specific microbial colonization. Microbes impact dissolution, transformation precipitation minerals through their activity, either genetically controlled or metabolism-induced biomineralization. Through these interactions, microbes co-evolve Earth history. typically occur at microscopic scale but the effect is often manifested global scale. Despite advances achieved decades research, major questions remain. Four areas are identified for future research: integrating mineral ecology, establishing biosignatures, linking laboratory mechanistic investigation field observation, manipulating mineral–microbe benefit humankind.

Abstract Elemental selenium (Se 0 ) nanomaterials undergo allotropic transition from thermodynamically‐unstable to more stable phases. This process is significantly different when Se nanoparticles (NPs) are produced via physico‐chemical and biological pathways. While the of physico‐chemically synthesized fast (minutes hours), biogenic takes months complete. The biopolymer layer covering NPs might be main factor controlling this retardation, but still remains an open question. Phylogenetically‐diverse bacteria reduce oxyanions red amorphous allotrope, which has low market value. Then, undergoes trigonal (metallic grey) end product having important industrial applications (e.g. semiconductors, alloys).

In addition, proposes conceptual model for resource potential in context circular economy.

Abstract Disruptive innovation is needed to raise the threshold of sustainable building performance, so that our buildings improve on net zero impacts and have a life‐promoting impact natural world. This article outlines new approach next‐generation architecture, which draws versatile metabolisms microbes as platform by incorporating microbial technologies microbially produced materials into practice built environment. The regenerative architecture arising from these interventions includes broad range advances using materials, creating bioreceptive surfaces promote life, providing green, bio‐remediating energy waste.

The Role of Microorganisms in the Nucleation of Carbonates, Environmental Implications and Applications

Minerals, Год журнала: 2022, Номер 12(12), С. 1562 - 1562

Опубликована: Дек. 3, 2022

Microbially induced carbonate precipitation (MICP) is an important process in the synthesis of minerals, and thus, it widely explored as a novel approach with potential for many technological applications. However, processes mechanisms involved mineral formation presence microbes are not yet fully understood. This review covers current knowledge regarding role microbial cells metabolic products (e.g., extracellular polymeric substances, proteins amino acids) on adsorption divalent metals, ionic species templates crystal nucleation. Moreover, they can play precipitation, size, morphology lattice. By understanding how their promote suitable physicochemical conditions (pH, Mg/Ca ratio free CO32− ions) to induce nucleation manipulation final precipitates could be reality (geo)biotechnological approaches. The applications implications biogenic carbonates areas such geology engineering presented discussed this review, major focus biotechnology.

Viruses participate in the organomineralization of travertines

Scientific Reports, Год журнала: 2023, Номер 13(1)

Опубликована: Июль 19, 2023

Abstract Travertines, which precipitate from high temperature water saturated with calcium carbonate, are generally considered to be dominated by physico-chemical and microbial precipitates. Here, as an additional influence on organomineral formation, metagenomic data microscopic analyses clearly demonstrate that highly diverse viral, bacterial archaeal communities occur in the biofilms associated several modern classic travertine sites Europe Asia, along virus-like particles. Metagenomic analysis reveals bacteriophages (bacterial viruses) containing icosahedral capsids belonging Siphoviridae, Myoviridae Podoviridae families most abundant of all viral strains, although bacteriophage distribution does vary across sampling sites. Icosahedral shapes also frequently observed under microscope, occurring non-mineralized through mineralized viruses Viruses initially Ca-Si amorphous precipitates subordinate Mg Al contents; these then alter nanospheroids composed Ca carbonate minor silicate 80–300 nm diameter. Understanding roles carbonate-saturated settings related organomineralization processes is critical for their broader inclusion geological record ecosystem models.

Controls on Mineral Formation in High pH Fluids From the Lost City Hydrothermal Field

Geochemistry Geophysics Geosystems, Год журнала: 2024, Номер 25(2)

Опубликована: Фев. 1, 2024

Abstract Although the serpentinite‐hosted Lost City hydrothermal field (LCHF) was discovered more than 20 years ago, it remains unclear whether and how presence of microbes affects mineralogy textures chimney structures. Most chimneys have flow comprised mineral walls bounding paleo‐channels, which are preserved in inactive vent structures to a varying degree. Brucite lines internal part these channels, while aragonite dominates exterior. Calcite is also present locally, mostly associated with brucite. Based on combination microscopic geochemical analyses, we interpret brucite, calcite, as primary minerals that precipitate abiotically from mixing seawater fluids. We observed local brucite precipitation microbial filaments and, some cases, may affect growth direction crystals. fluorescent carbonate minerals, possibly indicating organic compounds. Our results point an important substrate for life alkaline systems.
