Abstract

Microbially-mediated construction methods and microbial manufacturing of construction materials are new areas of Science and Engineering, which is the branch of construction microbial biotechnology. Production-related biotechnologies are primarily based on pastime of various microorganisms. These include cyanobacteria, algae, microscopic fungi as well as urease, acid, sodium, alkaline producers, as well as denitrifying, iron- and sulfate-decreasing microorganisms. The bio-associated substances and strategies may be used for bioaggregation, soil biogrouting and bioclogging, in crack remediation, self-healing, and biomediated ground improvement. Microbial biotechnology in costruction is progressing in the direction of business products and huge scale packages. The produced materials biotechnologically and construction-associated have lots of blessings over traditional created materials and methods such as cost effective and green alternative to traditional methods of stabilizing soils, it needs a reduced production time and the in-situ process raw materials of biocements are produced at low temperature. More efficient compared to ordinary cement which use temperature up to 1500˚C in production process. The successful commercialization of the technique requires economical alternatives of the medium ingredients that cost 61% of the operating costs. Factors affecting the use of bacteria in construction industry include type of the bacteria and their cell concentration, pH, temperature, calcium and urea concentration. Microbial concrete biotechnology has shown better qualities above several traditional technologies
