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.
全球生物柴油产量的增长表明，生物柴油已被公认为传统燃料的替代品。使用碱性催化剂生产生物柴油因其高转化率和短生产时间而得以商业化应用。对于生物柴油的产品和工艺开发，有人提出采用酶促酯交换反应，以便在温和的反应条件下，通过经济环保的工艺生产高纯度产品。酶成本是主要障碍，可通过固定化来克服。固定化酶已在各个领域成功应用，相比可溶性酶具有优势，可用于生物柴油生产，目的是通过酶的重复使用来降低生产成本。本综述旨在提供一份最新的汇编，内容涉及通过各种技术固定化脂肪酶生产生物柴油的相关研究报告，以及影响其功能的参数。
