Abstract

Emerging research highlights the potential of specific light spectral regions to significantly enhance microalgae biomass production compared to conventional white light illumination. However, conflicting results of existing studies on the most optimal wavelengths reveal a knowledge gap regarding the underlying factors for optimal spectrum. The present paper aims to address this gap by critically analyzing existing studies on light spectral quality and its impact on microalgae growth. The analysis focuses on identifying the key factors determining an optimal light spectrum for microalgae cultivation. The study critically evaluates the effects of narrow wavelengths, assessing whether monochromatic light may be effective in maximizing biomass yield. While wavelength manipulation has a high potential, a deeper investigation into combining narrow wavelengths at varying ratios to determine the most effective spectral composition for maximizing growth is required. The study aims to provide insights into designing an optimal light spectrum for sustainable and efficient microalgae cultivation.

揭示优化光谱促进微藻生长的潜在因素。

新兴研究强调了与传统白光照明相比，特定光谱区域显著提高微藻生物量生产的潜力。然而，关于最佳波长的现有研究结果相互矛盾，揭示了关于最佳光谱的潜在因素的知识差距。本文旨在通过批判性地分析现有的光谱质量及其对微藻生长的影响的研究来解决这一空白。分析的重点是确定决定微藻培养最佳光谱的关键因素。该研究批判性地评估了窄波长的影响，评估单色光是否可能有效地最大化生物质产量。虽然波长操纵具有很高的潜力，但需要更深入地研究以不同的比例组合窄波长，以确定最大化生长的最有效的光谱组成。该研究旨在为微藻可持续高效培养的最佳光谱设计提供见解。
