Statistical optimization of alkaline lipase production by extreme halophilic archean natrialba asiatica

In this study, extreme halophilic archean Natrialba asiatica was utilized as a new source for lipase production. Lipases from halophilic archaea are appealing for utilization in assorted industrial and biotechnological applications. The optimum temperature and pH of N. asiatica lipase in the crude mixture were 50 °C and 10, respectively. The growth conditions influencing lipase production were determined using a two-level fractional factorial Plackett–Burman design. Among the 9 factors screened, MgCl2 concentration, temperature, and shaking were found to be effective.
