Soil Enzymes as Indication of Soil Quality
2010Soil, water and air are natural resources as well as pollution reservoirs. Soil quality can be changed by pollution, ecological perturbations and agricultural practices. Soil quality can be defined as, “the capacity of a specific kind of soil to function, within natural or managed ecosystem boundaries, to sustain plant and animal productivity, maintain

Soil Enzyme Activities and Soil Fertility Dynamics
2012Soil fertility dynamics have been an interesting area in unravelling the diverse complexities involved with dynamic soil-plant relationship. Soil enzymes have been proven as the sensor against minutest edaphic, microbiological and biochemical changes in addition to soil contamination, often called nutrient cycling either as a result of intrinsic ...

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.

Michaelis constants of soil enzymes
Soil Biology and Biochemistry, 1971Abstract Studies to determine the Michaelis constants (km values) for the arylsulfatase and phosphatase activity in Iowa surface soils showed that the value obtained for either activity was different for different soils. When the incubation technique used to determine km did not involve shaking of the soil-substrate mixture, the km value for ...

Actinomycetes: Sources for Soil Enzymes
2010Soil is the most complicated biomaterial on the planet.It is a natural source for microorganisms and is a natural laboratory to do experiments. Soil, which arises from the weathering of parent rock materials, is by definition capable of acting as a habitat for microorganisms.

Lignocellulose-Degrading Enzymes in Soils
2010Biopolymers contained within or derived from plant biomass form are by far the largest pool of soil carbon. The decomposition of lignocellulose in the soil environment thus attracts considerable attention. Lignocellulose is composed mainly of the polysaccharidic polymers cellulose and hemicelluloses , and the polyphenolic polymer lignin .

Earthworm Interactions with Soil Enzymes
2010As one of the dominant members of soil fauna, earthworms fulfill significant tasks in the soil ecosystem by participating in the physico-chemical processes of the soil, such as organic matter cycles, nutrient transformations, and modifications in soil structure.
