About this Research Topic

Background

Minerals solubilization results from the dissolution of rocks and mineral substrates by microbial, mechanical, and chemical processes. The application of microorganisms in biomining is a biotechnological approach that involves extracting and recovering metals from ores. Microorganisms interact with minerals to colonize and exploit habitats and demonstrate the capacity to scavenge critical elements with low bioavailability, such as iron and phosphorus. There is an ongoing need to improve soil fertility and crop production, particularly in dry places, to remediate toxic soils and clean stone artworks and structures. A complete understanding of microorganisms-mediated mineral weathering processes may provide a significant opportunity for researchers to develop novel solutions to overcome challenges in agriculture, the environment, and industry.


Soil microbes play an essential role in the environment by releasing critical nutrients from primary minerals required for their nutrition and plant growth and development. They are also involved in element biotransformation and biogeochemical cycling, decomposition, weathering, and soil and sediment formation. Although the role of fungi in mineral weathering is beginning to be elucidated, the relative impact of bacteria in this process and the molecular mechanisms involved remain poorly understood. The capability of microorganisms to convert insoluble forms of mineral nutrients into absorbable forms makes them a very effective strategy in mineral-deficient soils. The phenomenon of making minerals available in soils through microorganisms is mineral solubilization. The principal mechanism for mineral solubilization could be the production of mineral-dissolving compounds such as organic and inorganic acids, siderophores, protons from ammonia assimilation, hydrogen sulfide, phytase, and phosphatases. These mineral solubilizing bioagents solubilize the fixed form of minerals into the available form and play an essential role in enhancing crop productivity. The current Research Topic will provide brief knowledge of several mineral-solubilizing microorganisms, particularly emphasizing their role in improving plant productivity. Apart from mineral solubilization, it will also cover the issues of weathering and bioremediation.

Frequently asked questions

• What is a Research Topic?

  Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

  Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

• Why does Frontiers publish Research Topics? 

  The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

  Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

• Why are Research Topics important for journals?

  As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

  A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

• How do we ensure the quality of articles within Research Topics?

  Each Research Topic must be approved by the specialty chief editor, and they fall under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

    In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

• What are the benefits of publishing my article in a Research Topic?

  Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

  As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

  Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

   
• What types of articles can be published in a Research Topic?

  Frontiers offers multiple article types, but it will depend on the field and section journals in which the Research Topic will be featured. The available article types for a Research Topic will appear in the drop-down menu during the submission process.
