Effect of Crude Oil on Invertase and Amylase Activities in Cassava Leaf Extract and Germinating Cowpea Seedlings

Akpovwehwee A. Anigboro and Nyerhovwo J. Tonukari
The effect of crude petroleum oil on invertase and amylase activities was determined directly in the assay medium using a crude extract of cassava (Manihot esculenta) leaf as source of invertase and amylase as well as in germinating cowpea (Vigna unguiculata L. Walp.) seedlings. There was a decreasing cowpea seedling invertase and amylase activities with increasing crude oil concentration in the soil. After three days of germination, the invertase and amylase activities in seedlings from 5.9% crude oil-treated soil decrease to 42 and 15%, respectively, compared to the control. A similar profile was obtained with invertase and amylase activities when crude oil was added directly to cassava extract enzyme assay. Addition of 10% crude oil in the assay inhibits invertase and amylase activities by 5.1 and 29.6%, respectively.
