(2014) Lipoxygenase and
Urease Inhibition of Extracts of Polygonatum verticillatum Rhizome: Augmented by its Isolated Compound, Santonin.
[beta]-glucosidase,
urease, phosphatase and protease (an enzyme involved in the progressive decomposition of the N contained in proteins) activity in soils treated with compost was greater than in soils that were not treated with compost (Crecchio et al., 2004).
The coating of urea with sulphur,
urease inhibitors and other biodegradable materials are the possible remedies to reduce N loss and enhance urea efficiency (Shaviv, 2001).
Dual specimens increase the diagnostic accuracy and reduce the reaction duration of rapid
urease test.
AAM: arginin ammonification (mg N[H.sub.4.sup.+]-N [kg.sup.-1] soil [h.sup.-1]); ALP: alkalin phosphomonoesterase activity (mg PNP [g.sup.-1] soil [h.sup.-1]); ARS: arylsulphatase activity (mg PNP [g.sup.-1] soil [h.sup.-1]), LGL: L-glutaminase activity (mg N[H.sub.4.sup.+]-N [kg.sup.-1]soil [h.sup.-1]); LAS: L-asparaginase activity (mg N[H.sub.4.sup.+]-N [kg.sup.-1]soil [h.sup.-1]); URS:
urease activity (mg N[H.sub.4.sup.+]-N [kg.sup.-1] soil [h.sup.-1])
A number of synthetic compounds including imidazoles, hydroxamic acids, and phosphazenes are effective
urease inhibitors, but limited studies have been conducted on natural products (Ahmad et al.
The activities of soil
urease, phosphatase, saccharase, and catalase in loam and clay soil were shown in Figures 4, 5, 6, and 7 and Table 1.

urease gene cluster," American Journal of Physiology: Gastrointestinal and Liver Physiology, vol.
Keeping in view the antiulcer use of the plant, the current study was designed to investigate
urease inhibitory properties of crude methanolic extract, total flavonoidal and sterol contents, and aqueous fraction of aerial parts of the plant in vitro.
(2008), soil saccharase activity is positively correlated with total nitrogen and available phosphorus, and
urease activity is negatively correlated with the soil pH.
pylori status was determined using the rapid
urease test (Pronto Dry).
