Special Issue Information

Dear Colleagues,

Extremophilic bacteria, capable of thriving in some of the most inhospitable environments on Earth, possess unique molecular mechanisms that enable their survival under extreme conditions such as high radiation, temperature, salinity, and pH levels. Understanding these mechanisms is not only crucial for advancing our knowledge of microbial resilience but also holds significant potential for innovative biotechnological applications.

This Special Issue, "Molecular Mechanisms of Extremophilic Bacteria and Their Potential Applications in Biotechnology", aims to explore the genetic, proteomic, and metabolic adaptations that confer extremophilic properties in these remarkable microorganisms. Additionally, it seeks to highlight the potential biotechnological applications of these adaptations, ranging from industrial processes to environmental remediation.

We invite contributions that delve into the following topics of interest:

  • Genomic insights into extremophilic bacteria;
  • Transcriptomic responses of extremophiles to extreme environmental conditions;
  • Proteomic and metabolomic profiling of extremophilic mechanisms;
  • Comparative studies between extremophilic and non-extremophilic bacterial strains;
  • Identification and characterization of key regulatory proteins and pathways;
  • Evolutionary adaptations and mechanisms underlying extremophilic bacteria;
  • Functional and structural analysis of stress response systems in extremophiles;
  • Applications of extremophilic bacteria in biotechnology, including bioremediation, bioenergy, and industrial bioprocesses.

By assembling a diverse range of studies, this Special Issue aims to provide a comprehensive view of the molecular, genetic, and evolutionary aspects of extremophilic in bacteria. Moreover, it seeks to uncover how these unique traits can be harnessed for various biotechnological innovations.

Ionic rare earth ore (IREO) has a high abundance of medium and heavy rare earth elements (REEs), making it a vital strategic resource for China. In this work, two typical microorganisms, Aspergillus niger and Acidithiobacillus ferrooxidans, were used to study the interaction mechanism during the bioleaching of IREO under acidic conditions. The results revealed some differences in the interaction and leaching effects of A. niger and A. ferrooxidans on ionic rare earth minerals. A. niger mainly forms rare earth complexes with rare earth ions in IREO by secreting metabolites such as organic acids, thereby promoting the release of REEs, and it has a strong adsorption capacity for Yb. A. ferrooxidans promotes the release of REEs from rare earth minerals, primarily through iron–sulfur oxidation. The differential expression of metabolic genes (e.g., gpmL, FabF, FASN) associated with major metabolite secretion indicates their correlation with the leaching process. The above results reveal the role of the typical acid-producing microorganisms A. niger and A. ferrooxidans and their metabolites in the leaching of IREO, which is valuable for understanding the interaction mechanisms between microorganisms and IREO under acidic conditions.
