Organic fertilization can increase [beta]-glucosidase, an enzyme that catalyzes the hydrolysis and biodegradation of various [[beta]-glucosidases found in the organic matter (Turner et al., 2002), and urease
activity (Chakrabarti et al., 2000, Chang et al., 2007).
renale contains the enzyme urease
(Timoney et al., 1988).
The main reason of these losses is the immediate increase in pH and NH4+ concentration around the fertilizer micro site due to the activity of enzyme urease
(Ahmed et al., 2008; Mohsina et al., 2004).When urea is applied to the soil, the soil pH and urea concentration increases immediately on the fertilizer microsite and urease
enzymes start their activity to hydrolyse the applied urea (Krajewska, 2009).
Detection of Helicobacter pylori: a faster urease
test can save resources.
activity of both genotypes was affected by the genotype and endophyte infection (Table 1).
Reaction mixtures comprising 25 [micro]l of enzyme (Jack bean urease
) solution and 55 [micro]l of buffers containing 100 mM urea were incubated with 5 [micro]l of test compounds (each 0.5 mM) at 30 [degrees]C for 15 min in 96-well plates.
The soil enzymes activities (urease
, phosphatase, saccharase, and catalase) of CT, DT, and DNT treatments in loam and clay were shown in Figures 4, 5, 6, and 7.

Being involved in the pathophysiology of multiple human and animal disorders, targeting urease
for treating pathogenic disorders caused by urease-producing bacteria has already opened a new line of treatment for infections caused by such bacteria.
The activity of soil urease
(EC 188.8.131.52) was determined in dry samples according to the Hofmann & Schmidt (1953) method and that of saccharase (invertase) (EC 184.108.40.206) according to the Hofmann & Seegerer (1950) method (both methods cited in and modified by Chunderova, 1973).
One sample was used for the rapid urease
test (Pronto Dry), the second for aerobic and anaerobic culture, and the third for histopathologic evaluation.
