Lipases have catalytic active in both aqueous phase and the non-aqueous phase and have a wide range of application in various industrial areas. However, the high cost of lipase production has restricted its extensive use in industry. Solid state fermentation possesses many advantages, such as low requirement for devices, low energy consumption, low production cost, little pollution to environment and easily being popularized, which have made it an important means in microbial production of lipases. Owing to the rapidly increased energy cost and the people's awareness of environmental protection, the solid state fermentation technique, which was regarded as low-tech in the past, has regained attention and developed rapidly since the 1990s. This paper reviews the production of lipase by SSF technique．Mainly contents describe its characteristics, including physical and chemical factors and bioreactors.
