Soil enzyme - soil amendment interactions.

2023
A simple, rapid and reproducible method of assaying 1,3-β glucanase activity in soil has been developed, using laminarin as a substrate. It was founded upon a detailed analysis of the factors involved such as: quantity, type and age of soil; choice of: buffer, substrate concentration, microbial inhibitor, pH, temperature and incubation time, and ...

Selected Soils, Insecticides and Soil Enzymes

2017
One of the chief commercial crops grown in Nandyal division (Andhra Pradesh, Southern India) is cotton, and it is the fourth crop next to groundnut, Bengal gram and jowar cultivated in this area. This crop is seriously damaged by many insect pests. For the effective control of the major insect pests on cotton grown in this region, an OP insecticide ...

Soil Enzymes: Indicators of Soil Pollution

2017
Soil enzymes are secreted by several organisms, but most often they are produced by soil microorganisms. An analysis of soil enzymatic activities is one of the microbiological indicators of soil quality. It has long been shown that enzymes participate in numerous biochemical processes occurring in soil, and as indicated by results of several studies ...

Enzymes in Forest Soils

2010
Forest soils are known to accumulate dead organic material (plant litter ) on the soil surface. When fresh, this material contains a range of substrates, including soluble saccharides, organic acids, amino acids or starch, as well as the plant cell wall-derived biopolymers, cellulose , hemicellulosesand lignin , which are used as growth substrates by ...

Soil Enzyme Activities as Biological Indicators of Soil Health

Reviews on Environmental Health, 2003
Soil health can be defined as the continued capacity of a specific kind of soil to function as a vital living system, within natural or managed ecosystem boundaries, to sustain plant and animal productivity, to maintain or enhance the quality of air and water environments, and to support human health and habitation. Because of the conflicting pressures

Extracellular Enzymes in Soils

Microbe Magazine, 2015
I found the recent article in Microbe (April 2015, p. 178) in the Small Things Considered section (“Microbe, Enzyme or Mineral? a Riddle in the Soil”) interesting and appreciated the focus on extracellular enzymes in soils. However, the presentation leaves the reader with the impression that the paper reviewed (J. Blankinship et al., Soil Biol. Biochem.

Microbial Enzymes and Soil Health

2021
Soil health is defined by its ability to function as a contribution to the good functioning of the beings that inhabit it. This includes plants, animals and microorganisms, acting in the filtration and regulation of water, degradation of chemical compounds and degradation of organic matter. When we talk about agriculture, this contribution means, among

Extraction of Enzymes from Soils

2021
Ninety years have passed since the first report was presented by Woods on oxidizing enzymes, especially peroxidase, in soils at the annual meeting of the American Association for the Advancement of Science in Columbus, Ohio. The enzyme activity of soils results from the activity of accumulated enzymes and from those in proliferating microorgansms ...

Decontaminating soil with enzymes

Environmental Science & Technology, 1992
Xenobiotics are manmade compounds often introduced into the environment at concentrations that cause undesirable effects. They can be transformed as a result of biotic and abiotic processes, leading to changes in their chemical state and ultimately in their toxicity and reactivity.
