Effects of Tetrabromobisphenol A on enzyme activity in soil
2011 International Conference on Remote Sensing, Environment and Transportation Engineering, 2011Tetrabromobisphenol A (TBBPA) is widely used throughout the world as flame retardant for electronic equipment or building materials, and is detected in air at the dismantling plant, sewage sludge, sediment or human serum samples. In the present study, we examined the effects of TBBPA on soil polyphenol oxidase, catalase and dehydrogenase activity by ...

Organo-Mineral–Enzyme Interaction and Soil Enzyme Activity
2010Although 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.

Sulfite oxidase enzyme activity in soil
Biology and Fertility of Soils, 2011Several 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, 1982Abstract 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

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 ...null Anamika +2 more

Influence of chlorothalonil on soil enzyme activity
2011 International Conference on Electric Technology and Civil Engineering (ICETCE), 2011In 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.

The Effect of Roxarsone on Soil Enzyme Activities
Applied Mechanics and Materials, 2012An indoor simulation experiment has been carried out to study the effects of Roxarsone on the soil neutral phosphatase, catalase and urease activity. The result showed that the enzyme activities were reduced by the Roxarsone, and the effect degree was aggravated with the increasing consistency.

Effect of waterlogging on enzyme activities in soils
Soil Biology and Biochemistry, 1988Abstract 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.
