摘要
随着近现代社会的高速发展,人类对于化石燃料的需求日益增加,大量埋藏在海底和地底的“碳”被采掘和利用,进入大气循环,使得温室气体增加、温室效应加剧,带来了冰川融化、海洋酸化等自然灾害,对生态环境和人类健康都造成了严重的威胁。就全球整体的碳循环过程而言,使用生物技术来固定并转化二氧化碳是最符合自然规律的方法。微藻生长速度快、二氧化碳固定效率高,是生物捕集二氧化碳的理想材料。从“碳中和”的定义和实现的必要性出发,综述了国内外微藻生物固碳技术的研究进展,并提出利用微藻进行二氧化碳固定,实现变“碳”为宝的可行方案,为“碳中和”目标的实现开辟新思路。
With the rapid development of modern society,mankind s demand for fossil fuels is increasing,and a large amount of“carbon”buried under the sea and underground is extracted and used to enter the atmospheric cycle,resulting in an increase in greenhouse gases and an intensification of the greenhouse effect,bringing about natural disasters such as glacial melting and ocean acidification,which pose a serious threat to the ecological environment and human health.This is a serious threat to the ecological environment and human health.The use of biotechnology to fix and transform carbon dioxide is the most natural way to address the overall global carbon cycle.Microalgae are ideal for biocapture of CO 2 because of their high growth rate and high CO 2 fixation efficiency.From the definition of“carbon neutrality”and the need to achieve it,the research progress of carbon sequestration technology of microalgae at home and abroad is reviewed,and a feasible solution is proposed to use microalgae for carbon dioxide fixation and to turn“carbon”into treasure.This paper presents a new way of thinking to achieve the goal of“carbon neutrality”.
