| contents | Intracellular diatom-derived carbon dots for enhancing photosynthetic efficiency and biomass production of Chlorella. Chen, Xiaoqi Zheng, Yimeng Zhang, Yuanshuai Chi, Zirong Zeng, Yanhua Huang, Aiyou Xie, Zhenyu Photosynthesis Biomass Chlorella Carbon Diatoms Quantum Dots Nitrogen Optimizing photosynthesis in microalgae is crucial for enhancing bioenergy production and addressing global energy demands. Here, the diatom-derived carbon dots (D-CDs) were synthesized through a hydrothermal method and explored their impact on the growth and photosynthesis of Chlorella. The results demonstrated that D-CDs significantly improved Chlorella growth, with a 59.4% increase in biomass, a 35.3% increase in proteins and a 118.9% increase in carbohydrates. The D-CDs penetrated the cells and interacted with chloroplasts, accelerating photosynthetic electron transfer during light-dependent reactions. This led to a 26.3% increase in ATP and a 55.5% increase in NADPH production. Transcriptomic analysis revealed that D-CDs upregulated ribosome-related genes and stimulated the expression of genes encoding nitrite reductase and glutamine synthetase, thereby enhancing nitrogen assimilation and utilization. This study highlights the potential of CDs derived from biomass in promoting Chlorella growth and enhancing photosynthesis, offering a promising approach for sustainable bioresource development. |
