Substrate solubility in steroid biotransformation is critical for enhancing the biotransformation of hydrophobic compounds. In this study, the sulfobutyl ether-β-cyclodextrin (SBE-β-CD) complexation technique was used for the biotransformation of β-sitosterol to androsta-1, 4-diene-3, 17-dione with Mycobacterium ATCC25795. The production yield was increased by 26.72%, and the biotransformation course was shortened by 24h using β-sitosterol/SBE-β-CD inclusion complexes as substrates (1.0 g/L). Fourier transform infrared spectroscopy and differential scanning calorimetry indicated that an inclusion complex was formed between SBE-β-CD and β-sitosterol. The complex significantly increased the solubility of β-sitosterol and improved the biotransformation efficiency of the substrate
