Pectin is a common anti-nutritional factor in plant feed,which affects the effective absorption of feed nutrients by animals.Pectinase refers to the general name of a variety of enzymes that can decompose pectin substances.Pectinase plays an important role in the field of biotechnology catalysis and accounts for 1/4 of the biological enzyme preparation market.Although pectinase is widely used and has formed a certain commercial scale,scholars at home and abroad are still expanding the source of pectinase production strains in recent years.Some researchers have tried to further increase the yield of pectinase by single or compound mutation breeding methods,and these studies have achieved breakthrough results.The biosynthesis of pectinase-producing strains,strain mutagenesis,genetic engineering and pectinase immobilization are mainly reviewed,and look forward to the broad prospect of pectinase,so as to provide a theoretical basis for expanding the new application field of pectinase.
