Abstract

The escalating accumulation of petroleum-based polymers has depleted resources and raised environmental concerns due to their non-recyclable and non-biodegradable nature. Consequently, there has been a growing interest in bio-based plastics, particularly algal-based biopolymers, which offer recyclability and eco-friendliness. Algae-derived polymers have distinct advantages, such as autotrophic growth reducing greenhouse gas emissions, rapid growth rate, low nutritional requirements, and resilience to harsh environments. Additionally, algae exhibit higher photosynthetic potential (10-20%) compared to terrestrial plants (1%-2%). The range of algal-derived polymers includes alginate, laminarin, fucoidan, carrageenan, agar, ulvan, polyhydroxyalkanoates (PHA), and poly-(Hydroxybutyrate) (PHB). However, further efforts are required to implement them on a large scale. This review highlights algae's potential as a raw material for biopolymer production, exploring their characteristics and applications in diverse industries like food and pharmaceuticals.

微藻作为生物聚合物可持续替代品的作用及其工业应用

石油基聚合物的不断积累耗尽了资源，并因其不可回收和不可生物降解的性质而引发了环境问题。因此，人们对生物基塑料越来越感兴趣，尤其是藻类基生物聚合物，它们具有可回收性和生态友好性。藻类衍生的聚合物具有明显的优势，如自养生长减少温室气体排放、生长速度快、营养需求低以及对恶劣环境的适应能力。此外，与陆地植物（1%-2%）相比，藻类表现出更高的光合潜力（10-20%）。藻类衍生聚合物的范围包括海藻酸盐、海带蛋白、褐藻糖胶、卡拉胶、琼脂、尺骨、聚羟基烷酸酯（PHA）和聚羟基丁酸酯（PHB）。然而，还需要作出进一步的努力，大规模地执行这些规定。这篇综述强调了藻类作为生物聚合物生产原料的潜力，探索了它们的特性及其在食品和制药等不同行业的应用。
