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.

Environmental Applications of Microorganisms

Environmental Applications of Microorganisms

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...

Responses to Drought and Flooding

Responses to Drought and Flooding

Water plays a significant role in the life cycle of plants. However, insufficient or excess of water can be detrimental and pose a serious threat to plants.

Metabolism of Chemolithotrophs

Metabolism of Chemolithotrophs

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.

Primary Production

Primary Production

The total amount of energy acquired by primary producers in an ecosystem is called gross primary production (GPP). However, of this energy, producers use some for metabolic processes, and some is lost as heat, decreasing the amount of energy available to the next trophic level. The remaining usable amount of energy is called the net primary productivity (NPP). In terrestrial ecosystems, NPP is driven by climate, while light penetration and nutrient availability drive NPP in aquatic ecosystems.

Background:

Internal nutrient loading from sediments significantly impacts lake eutrophication and recovery timelines.
Submerged macrophytes are a key restoration strategy for improving lake water quality.
The effects of macrophyte restoration on sediment nutrient dynamics and microbial communities remain understudied.

Purpose of the Study:

To investigate the impact of submerged macrophyte restoration on nitrogen and phosphorus storage and transformation in lake sediment-water systems.
To analyze the changes in sediment microbial community structure and function in response to macrophyte presence.
To compare the effects of different macrophyte species richness on nutrient cycling and microbial processes.

Main Methods:

Construction of two submerged macrophyte communities (species richness of two and five).
Monitoring of physicochemical parameters, nitrogen, and phosphorus dynamics.
Analysis of sediment microbiome structure and function across three plant growth stages (May, July, October).

Main Results:

Submerged vegetation significantly reduced nitrogen and phosphorus loads, including chemical forms, active concentrations, and release fluxes.
Macrophyte restoration altered sediment microbial communities, decreasing genes for nitrogen fixation, organic nitrogen metabolism, nitrification, and increasing genes for denitrification and phosphorus cycling.
Species richness and plant life cycle stages influenced nutrient loads and sediment microbiome responses.

Conclusions:

Submerged vegetation plays a vital role in regulating lake nutrient balance and sediment microbiomes.
Restoration of submerged macrophytes effectively mitigates internal nutrient loading and reshapes microbial nutrient cycling pathways.
Findings provide critical insights for aquatic ecosystem restoration and nutrient management strategies.
