ABSTRACT
Microbial lipases are important industrial biocatalysts with the character of stereoselectivity,site selectivity and high catalytic activity with few side effects.They have been used widely in many industrial and agricultural fields.The technology of protein engineering has been successfully applied to improve the activity and stability of microbial lipases,which will raise the competitive capacity of microbial lipase preparations and enlarge theirs application fields.The strategies,the problems and the prospects of protein engineering technology which have been applied to modify the microbial lipases was surveied.
ABSTRACT
Microbial lipase,one of important industrial biocatalysts,has been used widely in many industrial and agricultural fields.It is always the research focus to screen,mine and develop the microbial lipases with novel catalytic activity and high stability.This paper introduces briefly the pathways and methods to mine novel microbial lipase resources from six aspects,including extremophile,metagenome,genome database,protein engineering,immobilization,chemical modification,etc.
