Carbon-dioxide Fixation01:28

Carbon-dioxide Fixation

610
Carbon dioxide fixation in prokaryotes enables the assimilation of inorganic carbon into organic molecules, supporting biosynthetic pathways, sustaining ecosystems, and contributing to the global carbon cycle. It also has industrial applications in carbon capture and bioproduct synthesis. Autotrophic organisms rely on this process to utilize CO₂ as a carbon source in diverse environments.The Calvin CycleThe Calvin cycle is the most widespread carbon fixation mechanism, primarily used by...

The Calvin Benson Cycle

5.8K
Ribulose 1,5- bisphosphate carboxylase/oxygenase (RuBisCo) is a critical enzyme that catalyzes carbon dioxide assimilation during photosynthesis. However, it is an inefficient enzyme, having an extremely slow catalytic rate. A typical enzyme can process about a thousand molecules per second; however, RuBisCo fixes only around three-carbon dioxides per second. Photosynthetic cells compensate for this slow rate by synthesizing very high amounts of RuBisCo, making it the most abundant single...

C4 Pathway and CAM01:27

C4 Pathway and CAM

48.6K
Most plants use the C3 pathway for carbon fixation. However, some plants, such as sugar cane, corn, and cacti that grow in hot conditions, use alternative pathways to fix carbon and conserve energy loss due to photorespiration. Photorespiration is the process that occurs when the oxygen concentration is high. Under such conditions, the rubisco enzyme in the Calvin cycle binds O2 instead of CO2, which halts photosynthesis and consumes energy.

Area of Science:

  • Biotechnology
  • Environmental Science
  • Microalgal Cultivation

Background:

  • Efficient operation of CO2 absorption-microalgae conversion (CAMC) systems is crucial for carbon capture.
  • Matching nutrient supply with cellular demand is key to optimizing microalgal productivity.

Purpose of the Study:

  • To investigate the impact of different batch feeding strategies on microalgal growth and metabolism in CAMC systems.
  • To elucidate the molecular mechanisms behind enhanced microalgal performance under optimized feeding conditions.

Main Methods:

  • Implementation of various batch feeding strategies for microalgae cultivation.
  • Biomass concentration, bicarbonate utilization, and carbon fixation measurements.
  • Transcriptomic analysis to understand gene expression changes.

Main Results:

  • A specific batch feeding strategy (small, large, small amounts during adaptation, growth, and stable phases) outperformed direct nutrient addition.
  • This strategy led to significant increases in biomass concentration (9.8%), bicarbonate utilization efficiency (30.6%), and carbon fixation capability (12.0%).
  • Yields of chlorophyll (27.5%), carotenoids (10.1%), and carbohydrates (31.3%) were substantially enhanced.

Conclusions:

  • The optimized batch feeding strategy effectively enhances microalgal growth and carbon fixation in CAMC systems.
  • Transcriptomic analysis revealed that batch feeding up-regulates key metabolic pathways, including ribosome biogenesis, carbohydrate synthesis, the TCA cycle, and photosynthesis.
  • These molecular changes promote greater energy allocation towards carbon fixation and the accumulation of valuable biomass components.
