Volume : III, Issue : X, November - 2013 PRODUCTION OF HYDROLYTIC ENZYMES BY Beauveria bassiana ISOLATES ON SOLID MEDIUM Chinnadurai Subramanian And Ganesh Punamalai DOI : 10.9780/22307850, Published By : Laxmi Book Publication Abstract : The entomopathogenic fungus, Beauveria bassiana is of commercial importance as an alternative to
chemical insecticides in an agroecosystem. The fungal pathogen Beauveria bassiana is a widely used
mycoinsecticide for control of several insect pests, providing a biological alternative to synthetic chemical
insecticides. The potential Beauveria bassiana isolates (Bb – 1, Bb – 2 and Bb – 3) to produce different hydrolytic
enzymes such as chitinase, protease, amylase and lipase was determined in the present study by using the specific
substrates. Enzyme index value of extracellular enzymes (Chitinase, Protease, Caseinase, Lipase and Amylase)
produced by efficient Beauveria bassiana isolates was estimated in the present research. Maximum enzyme activity
was observed by the isolate Beauveria bassiana (Bb – 1) followed by Beauveria bassiana (Bb – 2) and Beauveria
bassiana (Bb – 3). Chitinase and protease activity of Beauveria bassiana isolates was investigated during Day – 2,
Day – 4, Day – 6, Day – 8 and Day – 10. Maximum chitinase and protease activity was observed by the isolate
Beauveria bassiana (Bb – 1) at Day – 4 followed by Beauveria bassiana (Bb – 2) and Beauveria bassiana (Bb – 3).
Minimum enzyme activity was recorded at Day – 10. Keywords : Article : Cite This Article : Chinnadurai Subramanian And Ganesh Punamalai, (2013).
