Zusammenfassung:	The invention provides an enzymatic process for preparing biodiesel from acidified oil, and relates to the technical field of biodiesel preparation. The enzymatic process for preparing biodiesel fromacidified oil comprises the following materials in parts by weight: 400-600 parts of raw oil, 40-60 parts of a bio-enzyme catalyst and 40-60 parts of methanol. The enzymatic process for preparing biodiesel from acidified oil comprises the following components in parts by weight: 500 parts of raw oil, 50 parts of a bio-enzyme composite catalyst and 50 parts of methanol. According to the process, the original process of carrying out solid enzyme reaction after liquid enzyme reaction and then distilling is changed into the process of carrying out distillation and then carrying out solid enzyme reaction, so that the reaction speed of the product is increased, and other substances such as pigments, colloids, non-fatty acid acidic substances, mechanical impurities and the like in the acidified oil can be separated throu
