Abstract: Enzyme is a kind of biological catalyst with high specificity and has been widely used in chemical industry, agricultural industry, biopharmaceutical industry, food industry, textile industry, feed industry and other industries. The commonly used industrial enzyme expression hosts include Escherichia coli, Bacillus, filamentous fungi, yeast, and lactic acid bacteria. Different expression hosts have different characteristics. For example, the bacterium hosts can quickly and easily over-express recombinant enzymes, but the bacterium systems cannot express very large eukaryotic proteins because of proteins requiring post-translational modifications. In recent years, the great progresses have been made in the high-level expression of industrial enzymes in different hosts. In this work, we systematically summarize the recent advances in the heterologous expression of industrial enzymes, and the development trends of heterologous expression of industrial enzymes are also prospected.
