Bioremediation00:46

Bioremediation

22.5K
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.

Green Algae01:21

Green Algae

931
Green algae, also referred to as chlorophytes, are different from red algae in having the chloroplasts containing chlorophylls a and b, which give them their distinct green hue. However, they lack phycobiliproteins, preventing them from developing the red or blue-green pigmentation seen in red algae. In terms of photosynthetic pigment composition, green algae closely resemble plants and share a close evolutionary relationship with them. Taxonomically Green algae belong to Phylum Chlorophyta in...

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...

Area of Science:

  • Environmental Science
  • Materials Science
  • Chemical Engineering

Background:

  • Harmful algal blooms (HABs) driven by eutrophication pose significant global threats to public health and aquatic ecosystems.
  • Developing sustainable methods to manage HABs and their environmental consequences is crucial.

Purpose of the Study:

  • To explore the utilization of HAB biomass for creating advanced functional materials.
  • To develop a novel strategy for controlled oxygen release and phosphate removal in aquatic environments.

Main Methods:

  • Algal biomass was converted into hollow mesoporous bio-hydrochar microspheres using hydrothermal carbonization.
  • Calcium peroxide (CaO2) was incorporated to create CaO2 core-mesoporous shell-CaO2 shell microspheres (OCRMs).
  • The performance of OCRMs in oxygen release and phosphate removal was evaluated.

Main Results:

  • OCRMs demonstrated significantly prolonged oxygen release (7x longer than direct CaO2 addition) due to their unique structure.
  • OCRMs achieved high phosphate removal efficiency (95.6%) with minimal impact on water pH.
  • The mesoporous shell effectively regulated oxygen release from the CaO2 core.

Conclusions:

  • The developed OCRMs offer a promising solution for managing eutrophication by providing controlled oxygenation and phosphorus sequestration.
  • Utilizing HAB biomass for creating functional materials presents a sustainable approach to environmental remediation.
  • The core-double-shell nanostructure of OCRMs enables multiple environmental benefits, including oxygen release, phosphate removal, and pH buffering.
