Green gold: Insights into the photosynthesis of microalgae
Microalgae are microscopic photosynthetic organisms that are central to a sustainable future. They convert light energy into chemical energy through photosynthesis and use this to produce organic compounds from inorganic substances such as CO2 and water. This process is essential for their growth and plays a crucial role in the Earth’s carbon and oxygen cycle.
The two-phase process of microalgal photosynthesis
The photosynthesis of microalgae essentially consists of two phases: the light-dependent reactions and the Calvin-Benson-Bassham cycle (CBB). In the light-dependent phase, microalgae capture photons with the help of special pigments organised in photosystems. This captured energy is then converted into ATP and NADPH, which drive the CBB cycle. This cycle harnesses these molecules to bind CO2 into organic compounds that are important building blocks for microalgal growth.

The importance of understanding photosynthesis in microalgae
Understanding the intricacies of microalgae photosynthesis is important not only for experts, but also for those interested in their enormous potential. Harnessing their power can open the doors to a more sustainable and environmentally friendly future. Further research highlights their multiple adaptations to photosynthesis, such as the carbon concentration mechanisms that enable efficient CO2 sequestration even at low concentrations. This property is important in the context of climate change, as it can potentially help curb CO2 levels while providing valuable biomass for industry.
Adaptive nature and future applications
In addition, certain microalgae species can switch between different photosynthetic pathways depending on environmental conditions and thus optimise energy production. This adaptability is attracting researchers who want to improve the cultivation of microalgae and expand their potential applications. Genetic engineering techniques such as CRISPR-Cas9 offer the potential to develop strains with improved photosynthetic efficiency tailored to specific applications such as biofuels and food supplements. Advances in photobioreactor technology and cultivation methods are shaping the future of microalgal applications, optimising photosynthetic processes for maximum productivity and minimum resource consumption.
