This paper describes an innovative biotechnology and civil engineering utilizing Microbiologically induced calcite precipitation MCIP for the improvement in properties of surface concrete. Newly, it is found that microbial mineral precipitation resulting from metabolic activities of favorable microorganisms in concrete enhanced the overall behavior of concrete. Calcite precipitation induced by Bacillus cereus was studied in three different percentage of incorporation of bacterial culture in Portland cement concrete specimens. Bacterial culture was mixed with basic ingredients of concrete to obtain microbial concrete. The addition of bacteria was found out to be very effective in increasing the strength of concrete. About 57% of increase in compressive strength was observed by microbial treatment. Different tests like EDTA and pH have also confirmed presence of calcium carbonate precipitation. Involvement of bacterial culture shows detrimental effect that bacteria can cause on the formation of passive layer that prevents rebar from its corrosion. SEM analysis have also confirmed the presence of bacteria forming spore further the following approach has also found out to be efficient in reducing water permeability in concrete structure.
