Botryococcus braunii is known for its high yield of extracellular hydrocarbons and polysaccharides. Hydrocarbons, especially botryococcenes and squalene can be used as not only fuels but also alternative feedstock for other fossil-based products. Exopolysaccharides excreted from B. braunii can be used as scaffolds for polyesters production, and have a notable potential for synthesis of nanoparticles. B. braunii is also a rich source of carotenoids, especially the unique secondary carotenoids such as botryoxanthins that have never been found in other microalgae. The morphology, physiology, and outer cell walls of B. braunii are complex. Understanding the colony structure shall provide insights into the mechanism of cell growth and chemicals secretion. It is possible to improve the production economics of the alga with advanced culture systems. Moreover, investigation of metabolic pathways for B. braunii may help us understand their regulation and provide valuable information for strain selection and optimal production of high-value chemicals.
胶球藻以其高产胞外碳氢化合物和多糖而闻名。碳氢化合物，特别是胶球藻烯和角鲨烯，不仅可用作燃料，还可用作其他基于化石的产品的替代原料。胶球藻分泌的胞外多糖可用作聚酯生产的支架，并且在合成纳米粒子方面具有显著的潜力。胶球藻也是类胡萝卜素的丰富来源，特别是独特的次生类胡萝卜素，如从未在其他微藻中发现的胶球藻黄质。胶球藻的形态、生理和外壳细胞壁复杂。了解群落结构可以深入了解细胞生长和化学物质分泌的机制。通过先进的培养系统，有可能提高藻类的生产经济性。此外，对胶球藻的代谢途径进行研究，有助于我们了解它们的调控机制，并为菌株选择和高价值化学品的最佳生产提供有价值的信息。
