“…Among the noteworthy immobilized enzymes there are also ureases (Krajewska 2009b;Marzadori et al 1998;Zhai et al 2010;Krajewska et al 1990). The enzymes are responsible for the hydrolysis of urea to carbonic acid and ammonia (Krajewska 2009a, Krajewska et al 2012.…”

“…The enzymes are responsible for the hydrolysis of urea to carbonic acid and ammonia (Krajewska 2009a, Krajewska et al 2012. The reaction can be exploited in removal of urea from aqueous solutions that is a problem faced in numerous areas, examples being urea-producing industry, agriculture and natural environment, food production and medicine (Krajewska 2009b). In the latter area, an immobilized urease was considered as a part of the wearable/portable artificial kidney, alternative to the classical hemodialytic device.…”

Endowed with unparalleled high catalytic activity and selectivity, enzymes offer enormous potential as catalysts in practical applications. These applications, however, are seriously hampered by enzymes' low thermal and chemical stabilities. One way to improve these stabilities is the enzyme immobilization. Among various tested methods of this process that make use of different enzyme-carrier interactions, immobilization by adsorption on solid carriers has appeared most common. According to these findings, in this review we present a comparative analysis of the literature reports on the recent trends in the immobilization of the enzymes by adsorption. This thorough study was prepared in order to provide a deeper understanding of the process. Both carriers, carrier modifiers and procedures developed for effective adsorption of the enzymes are discussed. The review may thus be helpful in choosing the right adsorption scheme for a given enzyme to achieve the improvement of its stability and activity for a specific application.

“…The first ureolytic microorganism, Micrococcus ureae, was isolated from urine in 1864 by van Tieghem. However, Musculus obtained the first ureolytic enzyme in 1874 from putrid urine, and as proposed by Miquel in 1890, it was named urease (see Mobley & Hausinger, 1989;Mobley et al, 1995;Krajewska, 2009). Initially, the ureolytic enzyme was considered to be a potent virulence factor in pathogenic bacteria such as Helicobacter pylori, Proteus mirabilis, Campylobacter pyloridis and Staphylococcus saprophyticus.…”

“…To date, the widest analytical application of urease has been for the quantification of urea in blood and urine (Francis, Lewis, & Lim, 2002). Recently, there has been a growing demand for urease in applications in other areas, such as food production (Krajewska, 2009). …”

“…Considering these things, calcium alginate mediated entrapment has attracted much attention [75]. Immobilization changes original enzyme properties like storage stability, kinetic parameter and customizes them for specific applications [76,77]. Furthermore, immobilization of enzymes enhances their thermal stabilities [54].…”

Geotechnical and geo-environmental engineering applications currently being explored through bio mineralization process include cementation of sands to improve mechanical properties and hence, to enhance bearing capacity and liquefaction resistance, sequestration of carbon, soil erosion control via surficial stabilization, groundwater flow control and remediation of soil and groundwater impacted by metals and radionuclides. Bio mediated system broadly refers to a chemical reaction series that are managed and controlled through biological activities and byproducts resulting from those reactions alter the properties of material in the system. Bio mediated methods such as microbial induced calcite precipitation (MICP), biofilm formation, biogas generation and biopolymers have been developed by injecting or stimulating microbes. MICP is the most widely explored method. Microbes having urease activity enhance the hydrolysis of urea and it helps to control the pH and to precipitate carbonate. Although it is a widely explored bio mediated method it has some disadvantages.The plant-derived urease may offer many benefits over microbial urease to induce carbonate cementation. Therefore, it is advantageous to explore the knowledge regarding such a technique as an eco-friendly method for different applications in the fields of geoenvironmental/geotechnical Engineering. The main objective of this paper is to provide an overview of the importance of plant-derived urease for different applications in the fields of geoenvironmental/ geotechnical engineering. The information presented in this paper may be important for biotechnologists/geoengineers to have wide ranging updates on the current situation.
