Abstract

Microalgae, as a large amount of renewable resources, is an important potential raw material for biofuel production. Anaerobic digestion is one of the most energy-saving technologies for microalgae to be converted into biofuels. However, the special properties of microalgae cell walls will limit the hydrolysis stage of the anaerobic digestion process, resulting in low conversion efficiency and less than the theoretical value of biogas production. In order to increase biogas production, microalgae must be pretreated to break down their hard cell walls and accelerate cell dissolution to increase biogas production. The methods of breaking the cell wall of microalgae are physical, chemical and biological. Physical and chemical technology can improve the production of biogas to a certain extent, but high energy consumption, easy to cause environmental pollution, making it impossible to achieve industrial application. Biotechnology can not only improve the production of biogas, but also is an environment-friendly pretreatment process with many advantages, such as low energy consumption, high efficiency, no corrosion, less derivative products, etc. However, pure enzyme reagent is expensive and economic benefits are not feasible. At present, low temperature pretreatment can make full use of process waste heat to reduce energy consumption, and will not cause secondary pollution, which is the most economically and technically feasible method.
