AB  - Building practices began with human civilization. Cement is the most commonly 
      used building construction material throughout the world. These traditional 
      building materials have their own environmental impact during production, 
      transportation, and construction, but also have limitations on building quality 
      and cost. Biological construction materials are currently emerging technology to 
      combat emissions from the construction sector. Different civil and biotechnology 
      researchers have turned to microorganisms for the production of bio construction 
      materials that are environmentally friendly, socially acceptable, and 
      economically feasible but can also produce high strength. Scanning electron 
      microscope (SEM) and X-Ray diffraction (XRD) are the most characterization 
      methods used to observe and ensure the production of calcite precipitate as 
      bacterial concrete. As compared to conventional concrete, bacterial concrete was 
      greater by 35.15% in compressive strength, 24.32% in average tensile strength, 
      and 17.24% in average flexural strength, and it was 4 times lower in water 
      absorption and 8 times lower in acid resistivity than conventional concrete. 
      Genetic engineering has great potential to further enhance the mechanical 
      strength of bacterial concrete for use in crack repairs in existing buildings.
