绿潮的迁移与大规模暴发,除了与藻体自身较强抗胁迫能力等生物学特性和海域环境条件有关外,也离不开藻际微生物的参与.微生物群落对藻类的生长、消亡等过程具有重要作用.不同环境条件下,浒苔共附生菌群落结构多样,对藻类的促进作用主要体现在藻体形态建成、生长、营养吸收以及光合作用等过程.在藻华发生过程中,能够帮助藻体高效吸收营养物质,促进藻类增殖,加剧绿潮的形成.因此,本文基于前人的研究成果,总结当前绿潮优势种浒苔共附生菌的研究现状,阐述浒苔共附生菌分离技术的建立过程,指出高通量测序等分子生物学技术对微生物群落结构与多样性分析的重要性,分析共附生菌对浒苔生长、繁殖、形态建成等生理特征和绿潮暴发的影响,探寻共附生菌在今后生产、生活中的应用价值,旨在为预测、防控绿潮暴发以及资源化利用开辟新思路.
Research Progresses and Application in the Growth-promoting Effect of Symbiotic and Epiphytic Bacteria on Green Tide-causing Ulva prolifera
The migration and large-scale outbreak of green tides are not only related to the biological characteristics such as the strong stress resistance of algae and the environmental conditions of the sea area,but also inseparable from the participation of algal microorganisms.The microbial community plays an important role in algal growth and extinction.Under different environmental conditions,the community structure of symbiotic and epiphytic microorganisms of Ulva prolifera are diverse.The promotion to algae growth is mainly reflected in the processes of algae morphogenesis,growth,nutrient absorption and photosynthesis.During the occurrence of algal blooms,U.prolifera could help the algae to efficiently absorb nutrients,promote algae proliferation,and thus increase the formation of green tides.Based on previous researching results,we summarized the current research status of symbiotic and epiphytic bacteria of U.prolifera,the dominant species of green tide,described the establishment process of the separation technology of symbiotic and epiphytic bacteria of U.prolifera,and pointed out the importance of molecular biology techniques such as high-throughput sequencing in the analysis of microbial community structure and diversity,analyzed the influence of these bacteria on the physiological characteristics of the growth,reproduction,morphogenesis of U.prolifera and the outbreak of the green tides,and explored the utilization value of symbiotic and epiphytic bacteria in future production and life,aiming to express new ideas for predicting and preventing and controlling the outbreak of green tides and for the algal utilization as a resource.
