Exploring the industrially important extracellular enzymes from different nematode-trapping fungi
Journal Title: International Journal of Life Science - Year 2018, Vol 6, Issue 2
Abstract
Nematophagous fungi are potential bio-control agent against the plant and animal parasitic nematodes. The extracellular hydrolytic enzymes are one of the important virulence factors for these fungi. In the present study, we investigated industrially important extracellular enzymes from two different genera of nematode-trapping fungi. Duddingtonia flagrans produced the highest amount of amylase (261 U/mL/min) and xylanase (76mU/mL/min) compared to Arthrobotrys conoides (186 and 39 U/mL/min) while it was reversed in case of cellulase, highest (214 U/mL/min) in A. conoides. Protease, chitinase and collagenase activity (236, 19.83 and 2.46 U/mL/min) was higher during induction in D. flagrans RPAN-10 as compared to A. conoides (118.6, 8.3 and 1.2 U/mL/min). D. flagrans RPAN-10 showed 3.14 fold and A. conoides 2.37 fold change in protease activity when induced with nematodes. However, there was no apparent difference in control and induced fungus for chitinase and collagenase. In summary, D. flagrans RPAN-10 was found to be a suitable candidate for further exploring the protease, amylase, chitinase and xylanase while A. conoides is suitable for cellulase production for further application. However, further research is required in order to optimization of growth conditions as well as suitable nutrients in order for large scale production for industrial applications.
