摘要

微藻已成为聚羟基烷酸酯（PHAs）的一种有前途和可持续的来源，其在生物塑料生产中的潜力日益得到认可。然而，微藻衍生pha的广泛应用面临着经济可行性和可扩展性方面的挑战。本文综合分析了微藻生产PHA的培养和优化的最新进展，强调了营养限制，特别是氮和磷在促进PHA积累中的关键作用。本综述还探讨了各种培养系统的有效性，包括自养、异养和混合养方法，以最大限度地提高PHA产量。环境因素如光照强度、盐度和pH值对PHA合成途径的影响进行了研究。此外，它还确定了必须解决的关键技术和经济挑战，以便将微藻生物塑料商业化，以充分利用微藻在可持续生物塑料生产中的潜力。

Polyhydroxyalkanoates production from microalgae for sustainable bioplastics: A review

Microalgae have emerged as a promising and sustainable source for polyhydroxyalkanoates (PHA), which are increasingly recognized for their potential in bioplastics production. However, the widespread application of microalgae-derived PHA faces challenges related to economic feasibility and scalability. This review provides a comprehensive analysis of recent advancements in the cultivation and optimization of microalgae for PHA production, highlighting the critical role of nutrient limitation, particularly nitrogen and phosphorus, in enhancing PHA accumulation. This review also explores the effectiveness of various cultivation systems, including autotrophic, heterotrophic, and mixotrophic approaches, in maximizing PHA yields. Environmental factors such as light intensity, salinity, and pH are examined for their influence on PHA synthesis pathways. Additionally, it identifies key technical and economic challenges that must be addressed to commercialize microalgae-based bioplastics to fully harness the potential of microalgae in sustainable bioplastic production.
