Enzymes have a wide variety of applications in diverse biotechnological fields, and the immobilization of enzymes plays a key role in academic research or industrialization due to the stabilization and recyclability it confers. In this study, we immobilized the Brassica oleracea chlorophyllase 1 (BoCLH1) or Candida rugosa lipase (CRL) in magnetic iron oxide nanoparticles-loaded alginate composi...

Lipases are placed only after proteases and carbohydrases in world enzyme market and share about 5% of enzyme market. They occur in plants, animals and microorganisms and are accordingly classified as plant, animal and microbial lipases. Wherever they exist, they function to catalyze hydrolysis of triglycerides to glycerol and fatty acid. Like carbohydrases and proteases, lipases of microbial o...

The effect of organic solvent on the structure and dynamics of proteins was investigated by multiple molecular dynamics simulations (1 ns each) of Candida rugosa lipase in water and in carbon tetrachloride. The choice of solvent had only a minor structural effect. For both solvents the open and the closed conformation of the lipase were near to their experimental X-ray structures (C(alpha) rms ...

Enzyme cost is the major problem for industrial scale application. Immobilization is a promising approach to moderate the enzyme cost factor and increase its stability and activity. In this study, sol-gel method was used to prepare the immobilization platform and entrapped lipase as one of the most used enzyme in dairy processing, cosmetics and pharmaceutical industries. Lipase from Candida rug...

Biodiesel production from Waste Palm Cooking Oil (WPCO) is of interest to substitute fossil derived diesel fuel, due its renewable nature, cleaner emissions and non-toxic properties. Thus, in this study, biodiesel through transesterification process was optimized using immobilized lipase Candida rugosa WPCO collected the faculty’s cafeteria as a feedstock. Interaction between five operating fac...

The molecular basis of chain length specificity of Candida rugosa lipase 1 was investigated by molecular modeling and site-directed mutagenesis. The synthetic lip1 gene and the lipase mutants were expressed in Pichia pastoris and assayed for their chain length specificity in single substrate assays using triglycerides as well as in a competitive substrate assay using a randomized oil. Mutation ...
