Bioremediation

Bioremediation

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.

Overview of Nitrogen Metabolism

Overview of Nitrogen Metabolism

Nitrogen is a very important element for life because it is a major constituent of proteins and nucleic acids. It is a macronutrient, and in nature, it is recycled from organic compounds and stored in the form of ammonia, ammonium ions, nitrate, nitrite, or nitrogen gas by many metabolic processes. Many of these metabolic processes are carried out only by prokaryotes.
The largest pool of nitrogen available in the terrestrial ecosystem is gaseous nitrogen (N2) from the air, but this...

The Roles of Bacteria and Fungi in Plant Nutrition

The Roles of Bacteria and Fungi in Plant Nutrition

Plants have the impressive ability to create their own food through photosynthesis. However, plants often require assistance from organisms in the soil to acquire the nutrients they need to function correctly. Both bacteria and fungi have evolved symbiotic relationships with plants that help the species to thrive in a wide variety of environments.

Area of Science:

Environmental microbiology
Bioremediation
Soil science

Background:

Polycyclic aromatic hydrocarbons (PAHs) are persistent soil pollutants.
Microbial remediation offers a sustainable solution for PAH contamination.
Understanding microbial diversity is crucial for optimizing bioremediation.

Purpose of the Study:

To investigate the diversity of phenanthrene-degrading bacteria in contaminated environments.
To identify dominant microbial strains responsible for PAH degradation.
To explore the relationship between microbial community composition and degradation efficiency.

Main Methods:

Isolation and screening of phenanthrene-degrading bacteria from sludge samples.
High-throughput sequencing for microbial community analysis.
Enrichment of functional microbial consortia through serial transfers.

Main Results:

Over 50% phenanthrene degradation was achieved across all samples.
Diverse bacterial communities were identified, with distinct compositions in different environments.
Enrichment led to the isolation of key genera like Achromobacter and Pseudomonas.

Conclusions:

Microbial community diversity plays a significant role in phenanthrene degradation.
Environmental conditions shape functional microbial groups for PAH remediation.
Future research should consider both degradation rates and microbial diversity variations.
