An overview on the role of photosynthetic microbes in biomineralization of calcite in bioconcretes


Mohammad Salim, Waseem Khan, Arvind Kumar Tripathi, Mohammad Shahid Masroor, Mohammad Rizwan Khan Bhina

The main objective of the present paper is to discuss the applications of microalgae to improve the quality of cement concrete. It deals with the study of urease producing algae like Chlorella vulgaris, Spirulina platensis, Synechocystis, Synechococcus, Scytonema, Picocyanobacteria and many others to produce bioconcretes in future. Microalgae are the photosynthetic microorganisms capable of producing calcite in bioconcretes. This is also called as microbiologically induced calcite precipitation (MICP) and could be a novel strategy to restore the concrete structures with the help of biomineralization of CaCO3 using microalgae in future. The review discusses the overall methodology of the culture of microalgae, biotechnology of bioconcrete production and the physicochemical and bioengineering properties of bioconcrete in association with microalgae.
