Microalgae are a potential feedstock for several bioproducts, mainly from its primary and secondary metabolites. Lipids can be converted in high-value polyunsaturated fatty acids (PUFA) such as omega-3, carbohydrates are potential biohydrogen (bioH) sources, proteins can be converted into biopolymers (such as bioplastics) and pigments can achieve high concentrations of valuable carotenoids. This work comprehends the current practices for the production of such products from microalgae biomass, with insights on technical performance, environmental and economical sustainability. For each bioproduct, discussion includes insights on bioprocesses, productivity, commercialization, environmental impacts and major challenges. Opportunities for future research, such as wastewater cultivation, arise as environmentally attractive alternatives for sustainable production with high potential for resource recovery and valorization. Still, microalgae biotechnology stands out as an attractive topic for it research and market potential.
微藻是几种生物制品的潜在原料，主要来自其初级和次级代谢物。脂质可以转化为高附加值的多不饱和脂肪酸（PUFA），如ω-3，碳水化合物是潜在的生物氢（bioH）来源，蛋白质可以转化为生物聚合物（如生物塑料），而色素可以达到高浓度有价值的类胡萝卜素。这项工作涵盖了目前从微藻生物质生产这些产品的实践，包括对技术性能、环境和经济可持续性的见解。对于每种生物制品，讨论都包括对生物工艺、生产力、商业化、环境影响和主要挑战的见解。未来研究的机会，如废水培养，作为可持续生产的具有吸引力的替代方案，具有高资源回收和增值潜力。尽管如此，微藻生物技术作为一个有吸引力的研究和市场潜力的主题仍然引人注目。
