Two novel clusters of nocardiopsis recovered from haloalkaline environment: Potential resource of multi-advantageous lipases

The principal features of lipases from all strains, not only from the most potent one, were realized in a comparative profile to prospect more of their possible advantages in industrial biocatalysis. Most of the lipases were thermophilic; the optimum temperature was 50-55°C in lipases from five isolates. Activation energy of all lipases varied considerably between 5.52 and 13.58 Kcal/mole. WN4L lipase exhibited the highest thermal stability (half-life time=99 min at 70°C).
