Effect of Toluene, KNO3 and Glucose on soil LGlutaminase activity

Abstract

At the PJTSAU Department of Soil Science and Agricultural Chemistry, incubation tests were conducted to see how toluene, KNO3 and glucose affect the activity of the soil enzyme L-glutaminase. Toluene has a considerable impact on the activity of L-glutaminase; it lowers enzyme activity in all soils. From 17.19 % to 36.06 %, the percentage drop in activity caused by the addition of toluene was more pronounced in black soils as compared to red soils. For six days, L-glutaminase activity increased in soils that had been incubated with either glucose or glucose-nitrate mixtures. Glucose and nitrate-treated soils were more active than soils that had only been nitrate-treated alone.
