Increase in volume of biodiesel production in the world scenario proves that biodiesel is accepted as an alternative to conventional fuel. Production of biodiesel using alkaline catalyst has been commercially implemented due to its high conversion and low production time. For the product and process development of biodiesel, enzymatic transesterification has been suggested to produce a high purity product with an economic, environment friendly process at mild reaction conditions. The enzyme cost being the main hurdle can be overcome by immobilization. Immobilized enzyme, which has been successfully used in various fields over the soluble counterpart, could be employed in biodiesel production with the aim of reducing the production cost by reusing the enzyme. This review attempts to provide an updated compilation of the studies reported on biodiesel production by using lipase immobilized through various techniques and the parameters, which affect their functionality.

使用固定化脂肪酶生产生物柴油-一项重要评论。

在世界范围内，生物柴油产量的增加证明了生物柴油已被公认为是常规燃料的替代品。由于其高转化率和低生产时间，使用碱催化剂生产生物柴油已经商业化。对于生物柴油的产品和工艺开发，已提出酶促酯交换反应可在温和的反应条件下以经济，环境友好的方法生产高纯度的产品。固定化可以克服酶成本的主要障碍。固定化酶已成功地应用于各种领域，超过了可溶性对应物，可用于生物柴油生产，目的是通过重复使用该酶来降低生产成本。
