Abstract
Urease is an enzyme produced by ureolytic microorganisms that can hydrolyzes urea to ammonia and carbon dioxide. Microbial urease has also been studied in clinical samples because it is associated with the level of pathogenic microorganisms virulences. Urease producing microbes can be isolated in different ecosystems such as soils and geological formations. This study aims to determine the optimum activity of urease production using gram negative bacteria in the presence of natural inhibitor (Allium sativum extract). The production of the enzyme was determine using Nessler method. The result showed that low concentration of Allium sativum inhibited the production of urease activity at 5000 ppm concentration.
