Microbial genetic resources, as part of world's biodiversity, are the backbone of all ecosystems. Their application in agri-food and industrial production has proven to be vital for the advancement of humankind. Today, amidst challenges stemming from population growth, climate change, shrinking arable land and increasing pollution, high-impact research on microbial genetic resources with the potential to strengthen the resilience of world agricultural production and safeguard human food security have been developed.

We developed a mathematical model to simulate dynamics associated with the proliferation of Geobacter and ultimately optimize cellular operation by analyzing the interaction of its components. The model comprises two segments: an initial part comprising a logistic form and a subsequent segment that incorporates acetate oxidation as a saturation term for the microbial nutrient medium. Given that four parameters can be obtained by minimizing the square root of the mean square error between experimental Geobacter growth and the mathematical model, the model underscores the importance of incorporating nonlinear terms.

Article Synopsis
  • * Researchers isolated various Bacillus strains from mine tailings in Zacatecas, Mexico, which can tolerate heavy metals and enhance soil quality by producing beneficial compounds like siderophores and IAA, and by solubilizing phosphates.
  • * The adaptations found in these Bacillus species, including specific genes for nutrient fixation and toxicity resistance, suggest they play a crucial role in helping ecosystems recover from mining impacts and could aid in phytoremediation efforts.

Electron microscopy is one of the tools required to characterize cellular structures. However, the procedure is complicated and expensive due to the sample preparation for observation. Atomic force microscopy (AFM) is a very useful characterization technique due to its high resolution in three dimensions and because of the absence of any requirement for vacuum and sample conductivity.
