Organo-Mineral–Enzyme Interaction and Soil Enzyme Activity

2010
Although we have come to know a great deal about the structure and function of enzymes for biomedical and industrial applications, much about the “real” properties of extracellular enzymes in the soil environment remains unknown due to their complex associations with soil organic matter (OM) and minerals.

Influence of chlorothalonil on soil enzyme activity

2011 International Conference on Electric Technology and Civil Engineering (ICETCE), 2011
In this paper, we studied the influence of different concentrations of chlorothalonil which was commonly used in North China, on the activities of soil invertase, catalase and urease. The results showed that the influence trend of chlorothalonil at different doses on soil enzyme activity was almost the same.

Sulfite oxidase enzyme activity in soil

Biology and Fertility of Soils, 2011
Several methods for measuring sulfite oxidases (EC 1.8.2.1 and EC 1.8.3.1) have been developed for microbial systems, but none have been systematically adopted for soils. We describe an assay method to measure sulfite oxidase in soil that is based on the use of potassium sulfite (K2SO3) serving as the substrate and electron donor, and potassium ...

Influence of Salinity on Soil Enzyme Activities

Soil Science Society of America Journal, 1982
Abstract Efforts were made to assess the levels of soil enzyme activities that have a specific role in the N, C, P, and S cycles of saline soils. Fieldmoist soil samples were treated with four rates of CaCl 2 , NaCl, and Na 2 SO

Enzyme activity in soils at subzero temperatures

Soil Biology and Biochemistry, 1975
Abstract Urease activity, phosphatase activity, and sulfatase activity were detected in soils at −10 and −20°C. The occurrence of enzyme activity in soils at subzero temperatures is attributed to enzyme-substrate interaction in unfrozen water at the surfaces of soil particles.

SOIL ENZYME ACTIVITIES AS INDICATORS OF SOIL HEALTH

Soil health is increasingly recognized as a fundamental determinant of agricultural sustainability, ecosystem functioning, and environmental quality. Among biological indicators, soil enzyme activities provide uniquely sensitive and process-based measures of soil functioning because they directly regulate the transformation and availability of ...

Effect of waterlogging on enzyme activities in soils

Soil Biology and Biochemistry, 1988
Abstract The activities of eight enzymes involved in C, N, P and S cycling were assayed in soils before and after waterlogging for times ranging from 0 to 10 days at room temperature (22°C). After waterlogging. Eh and pH were measured and the enzyme activities assayed at optimum pH values at 37°C.
