以海洋微藻为原料提取生物燃料的研究进展与发展趋势

The research progress and development trend on extraction of biofuel from marine microalgae

能源短缺已经引起了各国的广泛关注,各国科学家将目光投向生物燃料。然而由于大量使用玉米、大豆等农产品生产生物乙醇等燃料,导致生物燃料"与人争粮"和"与粮争地"现象严重。文章综述了用于提取生物燃料的海洋微藻藻种的筛选、纯化、大规模培养及采收方法的优缺点以及生物燃料的提取工艺等方面的主要进展,并对该产业的发展趋势进行了初步分析。

Energy shortages has caused widespread concern in all countries. The scientists turn to biofuels. However, due to largescale use of corn, soybeans and other agricultural products for production of biofuels such as ethanol, and the situation that biofuels compete food with human and compet earth with crops is serious. This paper reviewed the advantages and disadvantages of methods for screening, purification, large-scale cultivation and harvesting. Biofuel extraction art as well as the industrial development trend were analyzed.
