油脂提取是微藻技术生产生物燃料的主要瓶颈之一。提出了一种新的方法，该方法基于使用H2O2与或不与FeSO4，以破坏小球藻的细胞壁，并有利于随后从湿生物质中提取脂质。实验结果表明，当在合适的操作条件下进行破坏时，相对于应用经典方法的情况，提取的脂质的量显著增加。此外，鉴于其用于生产生物燃料的开发，破坏后提取的脂质的质量似乎得到改善。
Lipid extraction represents one of the main bottlenecks of the microalgal technology for the production of biofuels. A novel method based on the use of H2O2with or without FeSO4, to disrupt the cell wall ofChlorella vulgarisand favor the subsequent extraction of lipids from wet biomass, is proposed. Experimental results show that, when disruption is performed under suitable operating conditions, the amount of lipids extracted is significantly increased with respect to the case where a classical approach is applied. Moreover, quality of lipids extracted after disruption seems to be improved in view of their exploitation for producing biofuels.
