Abstract

Urease is an hydrolising enzyme produce by ureolytic microorganism which convert urea into ammonia and carbon dioxide. It is synthesized by a wide range organisms like bacteria, fungi, and some plants. Source of urease-producing microbes is generally distributed in soil and aquatic environments. Urease applications is used in medicine, agriculture and geotechnics. Nowadays, urease is as well extensively used as new alternative replacement of grouting material. The aim of the study was to determine effect of various substrate for grouting applications using enzyme and whole microbes. The result showed that highest strength of grouting materials was achieved using enzyme applications comparing to whole microbes.
