Isolation, Identification and Screening of Alkaline Protease from Thermophilic Fungal Species of Raipur
Journal Title: SSR Institute of International Journal of Life Sciences (SSR-IIJLS) - Year 2018, Vol 4, Issue 2
Abstract
Proteases are protein degrading enzymes that catalyses hydrolytic reaction in which protein molecules are degraded into peptides and amino acids. Thermostable alkaline proteases are of particular great interest for industrial application because they are stable and active at temperature above 60-70˚C. Thermophiles are found in wide array of environment such as mushroom compost material, nest, hay, wood chips, grains, soil, manure, coal mines etc. Alkaline proteases are most important industrial enzymes and they occupy about 60% of total enzyme market. From the soil samples, eight different fungal species were isolated through soil dilution plate method. In the present study, two fungi Aspergillus nidulans and Aspergillus glaucus from mushroom compost and two fungi Aspergillus terrus, and Aspergillus fumigates from cow manure, showing alkaline protease activity, were isolated. The zones of clearance were observed in Aspergillus nidulans, Aspergillus glaucus, Aspergillus terrus, and Aspergillus fumigatus species of fungi isolated from cow manure and mushroom compost. The best enzyme production was observed in Aspergillus terrus (1.005 ± 0.057 IU/mg protein) obtained from cow manure and the minimum enzyme activity was observed with Aspergillus glaucus (0.278 ± 0.026 IU/mg protein). However, more studies are required to assess the potential of Aspergillus nidulans, Aspergillus glaucus, Aspergillus terrus, and Aspergillus fumigatus species.
