influence of physical factors on extracellular lipase production in storage seed- borne fungi of some oil seeds

Fungal association in deterioration of seeds can better be correlated with the production of extra cellular hydrolytic enzymes. Therefore, dominant seed borne fungi of groundnut, sunflower and soybean were screened for their ability to produce extracellular lipase enzyme. Present study deals with the impact of physical factors such as temperature, pH and incubation period on extracellular lipase production in

Aspergillus niger, A. flavus, A. fumigatus, A. terreus, A. parasiticus, Fusarium moniliformae, F.oxysporum, Alternaria alternata, Curvularia lunata and Penecillium chrysogenum. The lipase enzyme assay was carried out by cup plate method. The degree of enzyme production was found to be variable among the mycoflora.
