The present paper deals with the study and scope of bioconcretes prepared with the applications of urease producing bacteria like Bacillus subtilis to produce rather more powerful and strengthen calcium carbonated bioconcrete and biogrouts in future. The paper discusses the overall methodology of bacterial culture, biotechnology of bioconcrete production and their physicochemical and bioengineering properties in the light of recent researches done so far in the same field. This could be a novel strategy to restore the concrete structures with the help of biominerlaziation of CaCO using bacteria in future. This is also called as microbiologically induced calcite precipita- 3 tion (MICP) and perhaps, one of the most important multidisciplinary works done so far in the fields of microbiology with civil engineering.
