Towards the development of systems for high-yield production of microbial lipases

Microbial lipases are a versatile and attractive class of biocatalysts for a wide variety of applications. Lipases can be produced by bacteria, yeasts or filamentous fungi. Nevertheless, they are often not optimal for direct use in industrial conditions due to low yields, low specific activities and a limited spectrum of activities. Improvements in the productivity of lipases have been made by genetic manipulation of the cell factory production hosts and by optimizing production media and conditions. Advances in protein engineering technology, ranging from directed evolution to rational design, have also been able to tailor lipases to particular applications. This review describes various approaches used to improve lipase production and applications.
