Identifying and addressing critical improvements in biomass, bioproduct and biofuel productivity is a priority for the nascent algae-based bioeconomy. Economic and sustainability principles should guide these developing improvements and help to unravel the contentious water–food–energy–environment nexus that algae inhabit. Understanding the biochemistry of the storage carbon metabolism of algae to produce biofuels and bioproducts can bring to light the key barriers that currently limit the overall carbon efficiency and the photosynthetic efficiency, and ultimately guide productivity and commercial viability in the context of limiting resources. In the analysis reported here, we present different potential pathways for a conceptual algae biorefinery framework, with each pathway addressing one of the main identified barriers to future deployment. We highlight the molecular identification, in the form of an extensive literature review, of potential bioproducts that may be derived directly from both biomass and fractions produced through a conversion pathway, for three important commercially-relevant genera of algae, Scenedesmus, Chlorella and Nannochloropsis. We establish a relationship between each of the potential bioproducts, describe relevant conversion and extraction processes, and discuss market opportunities with values and sizes as they relate to commercial development of the products.

发展用于生物燃料和生物产品的藻类生物精炼概念；对过程兼容产品的看法及其对降低成本的影响

识别和解决生物质，生物产品和生物燃料生产率的重大提高是基于藻类的新生生物经济的优先事项。经济和可持续性原则应指导这些不断发展的改进，并帮助阐明藻类栖息的有争议的水，食物，能源，环境之间的联系。了解藻类生产碳燃料和生物产品的储存碳代谢的生物化学特性，可以发现目前限制总体碳效率和光合效率的主要障碍，并最终在资源有限的情况下指导生产力和商业可行性。在这里报告的分析中，我们提出了概念藻类生物精炼框架的不同潜在途径，每种途径都解决了未来部署的主要障碍之一。Scenedesmus，Chlorella和Nannochloropsis。我们在每种潜在的生物产品之间建立关系，描述相关的转化和提取过程，并讨论与产品的商业开发相关的具有价值和规模的市场机会。
