  • Title: Lipase from solvent tolerant Pseudomonas aeruginosa strain: production optimization by response surface methodology and application.
    Author: Ruchi G, Anshu G, Khare SK.
    Journal: Bioresour Technol; 2008 Jul; 99(11):4796-802. PubMed ID: 17976982.
    Abstract:
    Solvent tolerant Pseudomonas aeruginosa strain PseA has been studied for lipase activity. This strain has earlier been reported to be secreting alkaline and solvent stable protease. It produced an extra cellular lipase with suitable properties for detergent applications viz. (i) alkaline in nature, (ii) stability and compatibility towards bleach oxidants, surfactants and detergent formulations and (iii) resistant to proteolysis. Since the culture supernatant contains both protease and lipase which are together required in detergent formulations, enzymes from P. aeruginosa seem ideal for use as detergent additive. P. aeruginosa lipase exhibited remarkable stability in wide range of organic solvents at 25% (v/v) concentration. This property can be useful for solvent bioremediation and biotransformations in non-aqueous media. Media optimization for cost effective production of lipase was carried out by response surface methodology which led to 5.58-fold increase in lipase production (4580 IU/ml) over un-optimized media.
