Abstract

Biocement is a promising alternative to conventional cement, offering advantages in sustainability and reducing carbon footprints. However, its widespread adoption has been hindered by the relatively high production costs. This review aims to explore various strategies and advancements in biocement production that can contribute to cost reduction. Specifically, we discuss the selection of low-cost microbial growth media for microbially induced carbonate precipitation (MICP), the utilization of plant extractives as enzyme substitutes in enzyme-induced carbonate precipitation (EICP), the substitution of urea with urine as a low-cost source of nitrogen, the exploration of affordable alternatives to calcium ions, and the valorization of ammonia/ammonium byproducts, and other pathways. The adoption of these strategies could significantly enhance biocement's scalability and sustainability, paving the way for more eco-friendly and cost-effective construction practices.

期刊介绍： World Journal of Microbiology and Biotechnology publishes research papers and review articles on all aspects of Microbiology and Microbial Biotechnology. Since its foundation, the Journal has provided a forum for research work directed toward finding microbiological and biotechnological solutions to global problems. As many of these problems, including crop productivity, public health and waste management, have major impacts in the developing world, the Journal especially reports on advances for and from developing regions. Some topics are not within the scope of the Journal. Please do not submit your manuscript if it falls into one of the following categories: · Virology · Simple isolation of microbes from local sources · Simple descriptions of an environment or reports on a procedure · Veterinary, agricultural and clinical topics in which the main focus is not on a microorganism · Data reporting on host response to microbes · Optimization of a procedure · Description of the biological effects of not fully identified compounds or undefined extracts of natural origin · Data on not fully purified enzymes or procedures in which they are applied All articles published in the Journal are independently refereed.
