Optimization of Effective Mcrobes for Soil Stabilization through Bacterial Calcite Precipitation

Abstract

Bacterial calcium carbonate(calcite) precipitation is a naturally occurring biological process in which bacteria produce inorganic materials as part of their basic metabolic activities. This technology has been widely explored and promising with potential in various technical applications.Sporosarcinapasturii GRI-AURO, Sporosarcinapasturii, Bacillus subtilisinaquosorum and Bacillus cereus are the bacteria isolated from termite soil and termite gut and identified with accession number. The above mentioned bacteria are ureolytic in nature.  These are capable of synthesis calcite crystals and take part in microbial soil stabilization. All morphological and biochemical tests emphasizes the properties of a particularly confined group of bacteria that can act as binding agents. The applications of bacterially produced carbonate biominerals for improving the durability of buildings, remediation of environment (water and soil), sequestration of atmospheric CO₂ etc. are discussed. The study also sheds light on benefits of bacterial biominerals over traditional agents and also the issues that lie in the path of successful commercialization of the technology of microbially induced calcium carbonate precipitation from lab to field scale.
