Diatoms for Carbon Sequestration and Bio-Based Manufacturing.

Area of Science:

• Biotechnology
• Environmental Science
• Marine Biology

Background:

• Carbon dioxide (CO2) is a primary greenhouse gas driving climate change.
• Diatoms are natural biological sinks for atmospheric CO2.
• Industrial cultivation of diatoms offers potential for carbon sequestration.

Purpose of the Study:

• To review current knowledge on diatoms for carbon capture.
• To evaluate the potential of diatoms in bio-based manufacturing.
• To explore methods for enhancing carbon fixation and product yield.

Main Methods:

• Review of existing literature on diatom cultivation and metabolism.
• Analysis of autotrophic and mixotrophic cultivation strategies.
• Exploration of metabolic pathways for carbon redirection.

Main Results:

• Diatoms can be cultivated industrially for CO2 sequestration.
• Metabolic diversity allows conversion of captured carbon into valuable products.
• Products include lipids, omega-3 fatty acids, pigments, and polysaccharides.

Conclusions:

• Diatoms hold significant potential for carbon capture and sustainable bio-manufacturing.
• Further research is needed to optimize CO2 uptake, fixation, and metabolic routing.
• Harnessing diatom potential can contribute to climate change mitigation and bio-economy.
