藻际微生物学：全面助推可持续发展的新兴交叉学科

Phycosphere Microbiology: an emerging interdiscipline comprehensively promoting sustainable development

摘要:

广泛分布在自然界中的藻类和细菌均是地球上最古老的生命形式，经过数十亿年的漫长自然进化，藻类与细菌演化成为以藻-菌相互作用为核心、“牵一发而动全身”的藻际生命共同体。构建这一复杂而精妙的藻菌共生系统的科学理论体系，并对其进行创新和发展，不仅对于人类探索生命起源与进化的奥秘具有重要的科学意义，而且，其在推动可持续发展的重要领域也展现出广阔的应用前景。在此背景下，作为微生物学的一个新的分支学科，藻际微生物学已经历了3个多世纪的孕育和发展。目前，推动其成为一门新兴交叉学科的时机已经到来。为此，本文深入探讨了藻际微生物学的核心概念；全面梳理了藻际生命共同体与地球环境保护、人类生命与健康、资源综合利用及绿色能源开发之间的紧密关系；系统回顾了藻际微生物学的发展历史，并归纳总结了其3个发展时期的主要研究成果。本文还对藻际微生物学的未来发展趋势进行了展望，并提出了若干潜在的交叉研究方向。

Abstract:

Algae and bacteria are both the oldest forms of life on our planet, and billions of years of natural evolution have driven the algae and their microbiomes to evolve into interactive phycobionts. Through complex, flexible, intelligent, and multi-interface interactions between algae and bacteria, the functions of both sides of the phycobionts are exquisitely regulated. The creation, innovation, and development of the phycobiont theory shows vital scientific value for revealing the mystery of the origin and evolution of the life on Earth, and this theory is also being transformed into diverse practical applications in significant fields for sustainable development. After centuries of incubation, knowledge accumulation and development, currently, it is the right time to promote Phycosphere Microbiology to develop into an emerging interdiscipline. In this review, we comprehensively discussed the core concepts of Phycosphere Microbiology, sorted out its vital relationships with environment protection, human health maintenance, resource utilization, and green-oriented transition of energy, then reviewed its development history, and summarized the main research achievements during three development periods. Finally, we also proposed and discussed the future development trends and potential research directions for this emerging interdiscipline.
