Microbes and Other Elemental Cycles01:24

Microbes and Other Elemental Cycles

23
Microbial activity plays a pivotal role in the biogeochemical cycling of iron and manganese, especially at the redox gradients characteristic of stratified aquatic environments. These cycles are driven by microbial transformations between oxidized and reduced forms of the metals, allowing organisms to exploit them for metabolic energy and structural purposes.Iron Cycling Across Redox GradientsIn neutral, oxygen-rich surface waters, iron is predominantly found in its oxidized, insoluble ferric...

Carbon-dioxide Fixation01:28

Carbon-dioxide Fixation

835
Carbon dioxide fixation in prokaryotes enables the assimilation of inorganic carbon into organic molecules, supporting biosynthetic pathways, sustaining ecosystems, and contributing to the global carbon cycle. It also has industrial applications in carbon capture and bioproduct synthesis. Autotrophic organisms rely on this process to utilize CO₂ as a carbon source in diverse environments.The Calvin CycleThe Calvin cycle is the most widespread carbon fixation mechanism, primarily used by...

Soil Microbial Ecology01:29

Soil Microbial Ecology

1
Soil microbial ecology is defined by highly diverse, spatially structured communities that drive nutrient cycling, organic matter turnover, and overall ecosystem stability. Although a gram of soil can contain thousands of bacterial and archaeal taxa, the ecological processes they mediate are even more crucial for sustaining terrestrial life.Microhabitats and NichesSoil is a heterogeneous mixture of minerals, organic matter, water, and air. Microbes inhabit distinct microhabitats formed by...

Responses to Heat and Cold Stress

15.6K
Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

Microbes and Climate Change

1
Microorganisms are pivotal agents in Earth's biogeochemical cycles, significantly influencing climate dynamics through their metabolic activities. These microbes modulate the levels of key greenhouse gases by both contributing to and helping mitigate climate change.Microbial Contributions to Greenhouse Gas EmissionsRising global temperatures accelerate microbial metabolism, which, in turn, speeds up the decomposition of organic matter. This process releases carbon dioxide (CO₂) through...

Factors Influencing Microbial Growth: Temperature01:27

Factors Influencing Microbial Growth: Temperature

1.7K
Microorganisms display remarkable adaptations, enabling them to thrive in diverse ecological niches across a wide range of temperatures. Temperature profoundly influences microbial growth by affecting enzymatic activity, membrane fluidity, and other cellular processes.Each microorganism operates within a specific temperature range defined by three cardinal points: minimum, optimum, and maximum. Below the minimum temperature, membranes lose fluidity, halting transport processes. Above the...

Area of Science:

  • Soil Science
  • Biogeochemistry
  • Environmental Science

Background:

  • Microbial extracellular enzymes bound to iron minerals regulate soil organic carbon (SOC) dynamics.
  • The effects of climate warming on these crucial mineral-enzyme interactions are not well understood.

Purpose of the Study:

  • To investigate the impact of climate warming on mineral-enzyme feedbacks controlling SOC stabilization.
  • To identify temperature thresholds and mechanisms governing these interactions along a climatic transect.

Main Methods:

  • Studied mineral-enzyme interactions across a 4000 km climatic transect (2-24 °C).
  • Utilized synchrotron-based microinfrared spectroscopy (n = 2783 spectra) to analyze mineral-organic residue interactions.
  • Assessed peroxidase activity as a key indicator of enzyme function.

Main Results:

  • Peroxidase activity showed a nonlinear response to temperature with a threshold around 20 °C.
  • Cooler climates with abundant short-range ordered (SRO) iron minerals enhanced enzyme activity and SOC accumulation.
  • Warmer climates with less SRO iron exhibited reduced enzyme sorption and SOC stabilization, linked to lower bioavailable carbon.
  • Warming decreased mineral retention of organic residues by over 30% due to weakened mineral-organic affinity.
  • Microbial necromass showed higher affinity for SRO minerals than plant residues.

Conclusions:

  • A temperature-sensitive mineral-enzyme feedback mechanism influences SOC stability.
  • This feedback is critical for predicting SOC dynamics and terrestrial carbon feedbacks under global warming.
