AB  - Cadmium (Cd) in paddy soil can be immobilized via microbially induced carbonate 
      precipitation (MICP), but it poses a risk to the properties and eco-function of 
      the soil. In this study, rice straw coupled with Sporosarcina pasteurii (S. 
      pasteurii) was used to treat Cd-contaminated paddy soil with minimizing the 
      detrimental effects of MICP. Results showed that the application of rice straw 
      coupled with S. pasteurii reduced Cd bioavailability. The X-ray diffraction (XRD) 
      and X-ray photoelectron spectroscopy (XPS) confirmed that Cd immobilization 
      efficiency was increased in the rice straw coupled with S. pasteurii treatment 
      via co-precipitating with CaCO(3). Moreover, rice straw coupled with S. pasteurii 
      enhanced soil fertility and ecological functions as reflected by the high amount 
      of alkaline hydrolysis nitrogen (AN) (14.9 %), available phosphorus (AP) 
      (13.6 %), available potassium (AK) (60.0 %), catalase (9.95 %), dehydrogenase 
      (736 %), and phosphatase (214 %). Further, the relative abundance of dominant 
      phyla such as Proteobacteria and Firmicutes significantly increased when applying 
      both rice straw coupled with S. pasteurii. The most significant environmental 
      factors that affected the composition of the bacterial community were AP 
      (41.2 %), phosphatase (34.2 %), and AK (8.60 %). In conclusion, using rice straw 
      mixed with S. pasteurii is a promising application to treat Cd-contaminated paddy 
      soil due to its positive effects on treating soil Cd as well as its ability to 
      reduce the detrimental effects of the MICP process.
