AB  - Microbially induced calcium carbonate precipitation (MICP) has emerged as a novel 
      technology with the potential to produce building materials through 
      lower-temperature processes. The formation of calcium carbonate bridges in MICP 
      allows the biocementation of aggregate particles to produce biobricks. Current 
      approaches require several pulses of microbes and mineralization media to 
      increase the quantity of calcium carbonate minerals and improve the strength of 
      the material, thus leading to a reduction in sustainability. One potential 
      technique to improve the efficiency of strength development involves trapping the 
      bacteria on the aggregate surfaces using silane coupling agents such as 
      positively charged 3-aminopropyl-methyl-diethoxysilane (APMDES). This treatment 
      traps bacteria on sand through electrostatic interactions that attract negatively 
      charged walls of bacteria to positively charged amine groups. The APMDES 
      treatment promoted an abundant and immediate association of bacteria with sand, 
      increasing the spatial density of ureolytic microbes on sand and promoting 
      efficient initial calcium carbonate precipitation. Though microbial viability was 
      compromised by treatment, urea hydrolysis was minimally affected. Strength was 
      gained much more rapidly for the APMDES-treated sand than for the untreated sand. 
      Three injections of bacteria and biomineralization media using APMDES-treated 
      sand led to the same strength gain as seven injections using untreated sand. The 
      higher strength with APMDES treatment was not explained by increased calcium 
      carbonate accrual in the structure and may be influenced by additional factors 
      such as differences in the microstructure of calcium carbonate bridges between 
      sand particles. Overall, incorporating pretreatment methods, such as amine silane 
      coupling agents, opens a new avenue in biomineralization research by producing 
      materials with an improved efficiency and sustainability.
