AB  - The detrimental effects of sand storms on agriculture, human health, 
      transportation network, and infrastructures pose serious threats in many 
      countries worldwide. Hence, wind erosion is considered a global challenge. An 
      environmental-friendly method to suppress wind erosion is to employ microbially 
      induced carbonate precipitation (MICP). However, the by-products of 
      ureolysis-based MICP, such as ammonia, are not favorable when produced in large 
      volumes. This study introduces two calcium formate-bacteria compositions for 
      non-ureolytic MICP and comprehensively compares their performance with two 
      calcium acetate-bacteria compositions, all of which do not produce ammonia. The 
      considered bacteria are Bacillus subtilis and Bacillus amyloliquefaciens. First, 
      the optimized values of factors controlling CaCO(3) production were determined. 
      Then, wind tunnel tests were performed on sand dune samples treated with the 
      optimized compositions, where wind erosion resistance, threshold detachment 
      velocity, and sand bombardment resistance were measured. An optical microscope, 
      scanning electron microscope (SEM), and X-ray diffraction analysis were employed 
      to evaluate the CaCO(3) polymorph. Calcium formate-based compositions performed 
      much better than the acetate-based compositions in producing CaCO(3). Moreover, 
      B. subtilis produced more CaCO(3) than B. amyloliquefaciens. SEM micrographs 
      clearly illustrated precipitation-induced active and inactive bounds and imprints 
      of bacteria on CaCO(3). All compositions considerably reduced wind erosion.
