Abstract: The aim of this study was to explore novel source of lipase from biodiversity hot spot region of Sikkim with activity at broad temperature range for application in detergent industry. Among the isolates, Pseudomonas helmanticensis HS6 showed activity at wide range of temperatures was selected for lipase production. Statistical optimisation for enhanced production of lipase resulted in enhancement of lipase activity from 2.3 to 179.3 U/mg. Lipase was purified resulting in 18.78 fold purification, 5.58% yield and high specific activity of 3368 U/mg. The partially purified lipase was found to be active in wide range of temperature (5–80 °C) and pH (6–9), showing optimum activity at 50 °C at pH 7. Peptide sequences on mass spectrometric analysis of purified lipase showed similarity to lipase family protein of three species of Pseudomonas. Both crude and purified lipase retained residual activity of 40–80% after 3 h of incubation with commercial detergents suggesting its application in detergent industry.
