AB  - Cerium is a critical element to modern technologies. Nowadays, its increased 
      applications have led to elevated levels in the environment. Cerium recovery by 
      microorganisms has gained a great deal of attention. Here, our research showed 
      that Bacillus licheniformis could be used to recover Ce(3+) from aqueous 
      solution. The adsorption capacity of cerium on this bacterial strain achieved 
      38.93 mg/g (dry weight) biomass. Adsorption kinetics followed a 
      pseudo-second-order rate model, and adsorption isotherm was fitted well with the 
      Freundlich model. Scanning electron microscope (SEM) observations coupled with 
      X-ray energy dispersive spectroscopy (EDS) analysis revealed a spatial 
      association of Ce with C, N, O, S, and P. Fourier transform infrared spectroscopy 
      (FT-IR) analysis further suggested that the phosphate and carboxyl groups on the 
      cell surface might be responsible for the adsorption of cerium. Furthermore, 
      X-ray diffraction (XRD) and transmission electron microscopy (TEM) with electron 
      energy loss spectroscopy (EELS) suggested that cerium initially occurred on the 
      bacterial cell surface as Ce(OH)(3), which was mainly converted to monazite 
      (CePO(4)) and a small amount of CeO(2) overtime. Hydrothermal treatment was used 
      to accelerate the mineralization process of cerium by B. licheniformis. The 
      hydrothermal treatment is conducted for comparative analysis of mineralization 
      process in extreme geological condition.
