Abstract 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 .
