Transformation

38
Microbial communities are dynamic environments where cell lysis releases free DNA into the surroundings. Other cells can take up this extracellular DNA through a process known as transformation.When a cell incorporates this foreign DNA into its genome, resulting in genetic modification, the process is known as transformation. Cells capable of this process are termed competent. Competence can be natural, as observed in certain bacteria and archaea, or artificially induced in the...

Microbial Nutrition

Organisms exhibit remarkable metabolic diversity, categorized based on how they acquire energy and carbon. These strategies enable survival in various ecological niches and are essential for maintaining energy flow and nutrient cycling within ecosystems.Energy and Carbon SourcesOrganisms are classified as phototrophs or chemotrophs based on energy acquisition. Phototrophs use light as their energy source, while chemotrophs rely on oxidizing chemical compounds. Further differentiation arises...

Summary

We stimulated petroleum reservoir microbes to enhance oil recovery by introducing a specific Pseudomonas strain. This strategy improved oil properties and facilitated heavy oil exploitation through optimized microbial communities and element cycling.

Area of Science:

  • Microbiology
  • Geochemistry
  • Biogeochemical Cycling

Background:

  • The lithospheric microbiome is crucial for global biogeochemical cycling, but mechanisms of microbial modulation in petroleum reservoirs are poorly understood.
