| Abstract | ||
| Ten soils are chosen from different geographic sites from Iraq :Abu Ghraib(Three soils) ,Al-Jadriya ,Dyala (Tow soils) , AL-Sulaimaniya,Al-Kut ,Al-Nasriya , Al-Dewniya they differ in their chemical and physical properties , to determine Kinetic values (activation energy and temperature coefficient ) of amidase enzyme in soils . The ten soils are incubated at 10-60 C° of incubation temperatures ,and amidase activity is determined at each degree to calculate kinetic values temperature coefficient (Q10) and activation energy (Ea) in soils .Results have shown that the increasing of temperature cause increasing hydrolysis of formamide (Amidase activity ) ,and the results have shown Q10 values of soils are between 1.83-2.37 ,where as Ea values are between 59.17- 86.61 K Jol.mol-1 . | ||
