Metabolism of Chemolithotrophs01:15

Metabolism of Chemolithotrophs

310
Chemolithotrophs are microorganisms that obtain energy by oxidizing inorganic molecules such as hydrogen gas (H₂), ammonia (NH₃), reduced sulfur compounds (H₂S, S²⁻), and ferrous iron (Fe²⁺). Unlike heterotrophic organisms that rely on organic carbon, chemolithotrophs transfer electrons from these inorganic donors to the electron transport chain (ETC), generating a proton motive force (PMF) that drives ATP synthesis through oxidative phosphorylation.

Environmental Applications of Microorganisms

445
Microorganisms play a pivotal role in maintaining ecosystem balance by recycling essential elements such as carbon, nitrogen, and phosphorus, as well as supporting processes like bioremediation, wastewater treatment, and biofuel production.Microbes in Elemental CyclesIn the carbon cycle, microorganisms decompose organic matter, releasing carbon dioxide via aerobic respiration. This carbon dioxide is subsequently used by photosynthetic organisms to synthesize organic compounds, closing the...

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...

Bioremediation00:46

Bioremediation

21.1K
Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.

Area of Science:

  • Microbiology
  • Environmental Science
  • Biotechnology

Background:

  • Solid waste decomposition involves anaerobic digestion (AD), a process mediated by methanogens.
  • The dynamics and metabolic diversity of methanogen communities during AD are not well understood.
  • Understanding these dynamics is key to optimizing methane production from waste.

Purpose of the Study:

  • To investigate methanogen community dynamics during solid waste decomposition.
  • To identify methanogenic pathways and their functional genes across different decomposition phases.
  • To correlate methanogen community structure with physiochemical parameters of solid waste and leachate.

Main Methods:

  • High-throughput Illumina MiSeq sequencing was used to analyze methanogen communities.
  • Phylogenetic Investigation of Communities by Reconstruction of Unobserved States (PICRUSt) was employed to predict metabolic pathways.
  • Redundancy analysis (RDA) was used to link community structure with environmental parameters.

Main Results:

  • Biodegradable matter (BDM) decreased significantly across aerobic, anaerobic acid, and methanogenic phases (55% to 13%).
  • Methanogen community structure varied significantly between phases, with distinct dominant taxa (e.g., Methanomicrobiales, Methanosarcinales).
  • Biochemical oxygen demand (BOD5) and nitrate levels were identified as key factors influencing methanogen composition; methanogenesis was inhibited during the acid phase.

Conclusions:

  • Methanogen community structure is dynamic and significantly influenced by nutrient availability during solid waste bioconversion.
  • Distinct methanogenic pathways (acetoclastic and hydrogenotrophic) were observed, with activity varying across decomposition phases.
  • This research provides novel insights into the mechanisms governing methanogen community structure and function in waste-to-energy processes.
