Abstract This study evaluates the effects of microbial processes in improving the swelling and shrinking properties of expansive soil. Elemental microanalysis，X-ray diffraction，Fourier-transform infrared spectroscopy and soil swelling-shrinkage tests were conducted to explore the changes in composition，content and structure of the mineral aggregate of expansive soil in bio-mediated treatment process，as well as the effects of microbial-induced mineral phase transformations on the swelling and shrinking characteristics of the soil. The experimental results indicate that cations Si4+，Al3+，K+，and Mg2+ in the microbial-soil reaction liquid continuously leached out over time. Notably，the concentration of K+ exhibited an initial increase followed by a decrease，reaching a peak at 14 days. The Si-O，Al-O and -OH bonds within montmorillonite crystals were also affected. It was suggested that K+ ions entered the interlayers of montmorillonite crystals，disrupting their structures. After 14 days of microbial activity，an illite-smectite mixed-layer peak appeared at 2θ = 9.882° in the expansive soil samples，and an illite peak was observed at 2θ = 48.07° after 28 days. Calculations using the K-value method proved a decrease in montmorillonite content and an increase in illite content. The free swelling rate and load swelling rate of the expansive soil decreased by 69.01% and 24.04%，respectively；the linear shrinkage rate and volumetric shrinkage rate decreased by 32.9% and 30.98%，respectively. The study reveals that Paenibacillus mucilaginosus effectively promotes the transformation of montmorillonite to illite and improves the swelling and shrinking properties of expansive soil，which provides a novel approach towards modifying some engineering properties of soils.

Key words： soil mechanics expansive soil montmorillonite Paenibacillus mucilaginosus phase transition swell- shrink properties
