近日，马来西亚思特雅大学Siti Hamisah Tapsir教授团队在《Frontiers in Energy》发表了题为“Glow-in-the-dark: Exploring the opportunities and challenges of bioluminescent plankton as a natural light source”的Highlights文章。该论文深入探讨了利用生物发光浮游生物作为天然光源的潜力与挑战，为未来绿色照明和能源技术提供了新视角。

# 文章主要内容#

生物发光浮游生物是一类能够通过体内化学反应发出蓝色光芒的海洋生物，其发光现象俗称“蓝眼泪”，目前广泛应用于生态、海洋和生物学研究，而在能源和照明领域的应用仍处于探索阶段。其发光原理基于荧光素酶-荧光素反应，可产生高效“冷光”，能量损耗极低，部分培养体系甚至能够达到100瓦白炽灯的亮度。

与传统光源相比，生物发光技术有望实现独立于电网的天然照明，减少碳排放并提升能源利用效率。然而，这项技术面临多个挑战，包括如何实现生物的高效分离和大规模室内培养、稳定控制发光输出、筛选安全菌株以及优化发光强度等。此外，发光受昼夜节律影响，需要外部刺激维持稳定性。未来研究方向包括开发智能化培养体系、提取发光物质用于医药和商业领域，以及通过基因工程拓展应用场景。尽管存在技术和经济挑战，生物发光浮游生物作为可持续发展的一部分，展现出巨大的应用潜力。

Abstract:

Bioluminescent plankton are marine organisms capable of emitting visible light through chemical reactions in their bodies. This unique biochemical trait is attributed to a luciferin-luciferase reaction, which produces a striking blue light. This fascinating phenomenon, often referred to as the “blue tears” effect, has become a major attraction for tourist attractions in many countries. Since their discovery, most investigations related to these marine organisms have primarily focused on the fields of biology, ecology, oceanography, and microbiology. However, there has been limited to almost no study of their potential applications in the area of energy or lighting. This paper provides viewpoints on the opportunities for using these marine organisms and their light-emitting characteristics as an energy-efficient and environmentally friendly lighting solution, rather than just as a tourist attraction. Additionally, it addresses the challenges associated with sustaining the growth of bioluminescent plankton collected from the marine environment, the importance of establishing suitable protocols for in-house cultivation, challenges in stimulating the light-production at desired time, constraint imposed by the circadian rhythm, the toxicity of certain bioluminescent plankton, and the capacity of their luminous intensity.
