摘要
高效生物生产碳氢化合物是解决石油等液体燃料短缺的有效手段之一,而微藻油是生产可持续生物燃料的可靠选择.布朗葡萄藻(Botryococcus braunii)是一种由单细胞组成的不定形群体绿藻,能够积累大量碳氢化合物,最高含量可达其干重的75％,因而受到广泛关注.近年来随着对葡萄藻生物学特性和生长生理的不断深入研究,提高了其规模化培养及其碳氢化合物工业化生产的可行性.从生物学特性、碳氢化合物合成途径及调控因子、多组学研究和规模化培养技术几方面简单叙述了布朗葡萄藻作为新型产油微藻生产碳氢化合物的潜力,为探索利用布朗葡萄藻大规模工业化生产生物燃料提供参考,从而加速该微藻资源的开发利用.
Abstract
Highly efficient bioproduction of hydrocarbons is one of the effective means to solve the shortage of petroleum and other liquid fuels,while microalgae-based oils are a reliable choice for the production of sustainable biofuels.Botryococcus braunii is an irregular unicellular colony belonging to the chlorophyta,which has received widespread attention for accumulating the large amounts of hydrocarbons,with a maximum content of up to 75％of its dry weight.In recent years,continued in-depth research into the biological characteristics and growth physiology of B.braunii,has improved the feasibility of its large-scale cultivation and industrial production of hydrocarbons.In this review,the potential of B.braunii as a novel oleaginous microalga for hydrocarbon production was briefly described from the aspects of biological characteristics,hydrocarbon synthetic pathways and regulatory factors,omics studies,and large-scale cultivation techniques.This could provide a reference for exploring the large-scale industrial production of biofuels based on B.braunii,thus accelerating the development and exploitation of this microalgal resource.
