Abstract

Biocementation is an eco-friendly process in sustainable construction; however, the associated cost of nutrients is major obstacle in it. Therefore, the main objective of this study was to utilize tofu wastewater (TW) in biocementation to grow Bacillus cereus and desirable characteristics were compared with that in commercial nutrient broth. There was no significant difference in bacterial growth between two media with TW as preferable media for growth and urease activity on which biocementation depends. Further, an improved compressive strength of sandstone and mortars was achieved with TW, showing important insights into the greater feasibility of TW as biocementation source.
