Environmental Applications of Microorganisms

3
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...

Bioremediation00:46

Bioremediation

18.2K
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.

Microorganisms in Agriculture and Food industry

3
Microorganisms play a crucial role in agriculture and the food industry, contributing to soil fertility, crop protection, and food production. Their functions range from nitrogen fixation and biopesticide production to fermentation and food preservation, making them indispensable to sustainable farming and food safety.Role in AgricultureNitrogen-fixing bacteria, such as Rhizobium (symbiotic) and Azotobacter (free-living), convert atmospheric nitrogen into ammonia through biological nitrogen...

Area of Science:

  • Environmental Science
  • Soil Science
  • Microbiology

Background:

  • High molecular weight polycyclic aromatic hydrocarbons (PAHs) like chrysene degrade soil quality and impact food crop safety.
  • Compost is used to remediate contaminated soil, but its specific components enhancing chrysene biodegradation are unknown.

Purpose of the Study:

  • To investigate the enhancing effects and mechanisms of kitchen compost (KC) and kitchen compost-derived dissolved organic matter (KCOM) on chrysene removal from soil.
  • To identify key components within kitchen compost that influence chrysene degradation.

Main Methods:

  • Cultivation experiments were employed to assess chrysene removal.
  • High-throughput sequencing technology was used to analyze microbial community changes.
  • Correlation analyses were performed to link soil properties, organic matter structure, and microbial activity to chrysene degradation.

Main Results:

  • Kitchen compost-derived dissolved organic matter (KCOM) was identified as the primary component promoting chrysene degradation.
  • KC and KCOM treatments increased chrysene degradation rates by 27.20% and 24.18%, respectively, compared to controls.
  • KC and KCOM improved soil nutrients, accelerated organic matter humification, and boosted microbial activity, enhancing the abundance of key chrysene-degrading bacteria.

Conclusions:

  • KCOM is the main active component in kitchen compost responsible for enhancing chrysene biodegradation.
  • Optimizing soil properties and organic matter structure through KC and KCOM application promotes microbial communities essential for chrysene remediation.
  • This research offers insights into microbial-enhanced remediation strategies for chrysene-contaminated soils.
