Summary
The behaviour and state of soil catalase, dehydrogenases, urease and proteases associated with different soil structural fractions were studied. Assays of the enzymatic sensitivity to pH variation, thermal stability and the calculation of kinetics constants of Michaelis were performed. The results indicated that catalase and urease activity in these soils seem to be of the same type, because the activities presented a similar behaviour in the soil fractions studied. However, their state appeared different in each group of soil units. Dehydrogenases showed a similar state and behaviour while proteases were in a different state and behaviour in each soil fraction.
