Microalgae are a promising source of raw material (i.e., proteins, carbohydrates, lipids, pigments, and micronutrients) for various value-added products and act as a carbon sink for atmospheric CO2. The rigidity of the microalgal cell wall makes it difficult to extract different cellular components for its applications, including biofuel production, food and feed supplements, and pharmaceuticals. To improve the recovery of products from microalgae, pretreatment strategies such as biological, physical, chemical, and combined methods have been explored to improve whole-cell disruption and product recovery efficiency. However, the diversity and uniqueness of the microalgal cell wall make the pretreatment process more species-specific and limit its large-scale application. Therefore, advancing the currently available technologies is required from an economic, technological, and environmental perspective. Thus, this paper provides a state-of-art review of the current trends, challenges, and prospects of sustainable microalgal pretreatment technologies from a microalgae-based biorefinery concept.

微藻生物质预处理和增值产品回收的新趋势:综述
微藻是各种增值产品的原材料(即蛋白质、碳水化合物、脂质、色素和微量营养素)的有前途的来源,并且充当大气中 CO 2的碳汇. 微藻细胞壁的刚性使其难以提取不同的细胞成分用于其应用,包括生物燃料生产、食品和饲料补充剂以及药物。为了提高微藻产品的回收率,已经探索了生物、物理、化学和组合方法等预处理策略,以提高全细胞破碎和产品回收效率。然而,微藻细胞壁的多样性和独特性使得预处理过程更具物种特异性,限制了其大规模应用。因此,需要从经济、技术和环境的角度推进现有技术。因此,本文提供了对当前趋势、挑战、
