Fundamental to the Old Testament understanding of joy are God's Acts in history, themost important of which is Israel's deliverance from Egypt (Exod 18:9-11).Israel's return from the Babylonian exile (Jer 31:1-19) toJerusalem is above the highest joy (Psalm 137:6).he element of joy in religion is still more prominent in the New Testament. It is the appropriate response of the believer to the good tidings of great joy which constitute the gospel (Luke 2:10). In the four Gospels, especially Luke, this element is conspicuous.
1 Obtain your tube and compare it to a control. 2  If the color is intensely deep pink after 2 days, it is positive for rapid urease hydrolysis.  If it is yellow or orange, the test is negative. The organism either does not hydrolyze urea rapidly or it cannot live in the medium.
Urease Test. Urease broth is a differential medium that tests the ability of an organism to produce an exoenzyme, called urease, that hydrolyzes urea to ammonia and carbon dioxide.rea broth is formulated to test for rapid urease-positive organisms. The restrictive amount of nutrients coupled with the use of pH buffers prevent all but rapid urease-positive organisms from producing enough ammonia to turn the phenol red pink. Important: In our lab, we only use the urease broth, not the agar.
