Abstract

This review hypothesizes that algal biomass, an underexplored and promising raw material, offers significant potential for polyhydroxyalkanoate (PHA) production within sustainable bioprocess frameworks. The increasing urgency to find alternative, eco-friendly solutions to traditional plastic production is driven by growing environmental concerns over plastic pollution. The review highlights novel interdisciplinary connections between algal biomass utilization, bioremediation, and PHA biosynthesis, revealing new pathways that optimize renewable resource use and enhance waste valorization. These hybrid processes, combining microalgal and cyanobacterial biomass after bioactive compound extraction, have not been sufficiently explored, presenting significant environmental and economic opportunities for the bioplastics industry. Additionally, the integration of artificial intelligence (AI) in the development of PHA + algal biomass biocomposites, with desirable properties for industrial and medical applications, presents a breakthrough opportunity. Future research should focus on advancing pretreatment methods to improve fermentable carbohydrate availability, scaling up production, and addressing challenges related to energy efficiency, cost-effectiveness, and the commercial viability of these biocomposites in the bioplastics market.

迈向可持续生物塑料：藻类生物质在PHA生产和生物复合材料制造中的潜力

这篇综述假设藻类生物量是一种未被充分开发和有前途的原料，在可持续的生物过程框架内为聚羟基烷酸酯（PHA）的生产提供了巨大的潜力。人们越来越迫切地需要找到替代传统塑料生产的环保解决方案，这是由对塑料污染日益增长的环境担忧推动的。这篇综述强调了藻类生物量利用、生物修复和PHA生物合成之间新的跨学科联系，揭示了优化可再生资源利用和增强废物增值的新途径。这些混合工艺，结合生物活性化合物提取后的微藻和蓝藻生物量，尚未得到充分的探索，为生物塑料工业提供了重要的环境和经济机会。此外，人工智能（AI）在PHA +藻类生物质生物复合材料开发中的集成，具有理想的工业和医疗应用性能，提供了一个突破性的机会。未来的研究应该集中在推进预处理方法，以提高可发酵碳水化合物的可用性，扩大生产，并解决与能源效率、成本效益和这些生物复合材料在生物塑料市场上的商业可行性相关的挑战。

期刊介绍： Process Biochemistry is an application-orientated research journal devoted to reporting advances with originality and novelty, in the science and technology of the processes involving bioactive molecules and living organisms. These processes concern the production of useful metabolites or materials, or the removal of toxic compounds using tools and methods of current biology and engineering. Its main areas of interest include novel bioprocesses and enabling technologies (such as nanobiotechnology, tissue engineering, directed evolution, metabolic engineering, systems biology, and synthetic biology) applicable in food (nutraceutical), healthcare (medical, pharmaceutical, cosmetic), energy (biofuels), environmental, and biorefinery industries and their underlying biological and engineering principles.
