Optimization of Process Parameters for the Production of Lipase in Solid State Fermentation by Yarrowia Lipolytica from Niger Seed Oil Cake (Guizotia Abyssinica)

摘要

Lipases (triacylglycerol acylhydrolases, EC 3.1.1.3) are one of the most important classes of industrial enzymes. They hydrolyse triglycerides into diglycerides, monoglycerides, glycerol and fatty acids. In recent years, there has been an increasing interest in the study of lipases mainly due to their potential applications as medicines (digestive enzymes), food additives (flavour modifying enzymes), clinical reagents (glyceride-hydrolysing enzymes) and cleaners (detergent additives) (Sharma et al., 2001). Additionally, a promising application field for lipases is in the biodegradation of plastics such as polyhydroxyalkanoates (PHA) and polycaprolactone (PCL) (Jager et al., 1995; Mochizuki et al., 1995). Lipases would be economically manufactured in solid state fermentation.
