AB  - Biological Mn(II) removal usually involves adsorption and precipitation of Mn(II) 
      in the form of various minerals. Manganese oxides (MnO(x)) formation through the 
      activity of Mn(II) oxidation bacteria (MnOB) contributes to the majority of 
      Mn(II) removal. However, whether other bacterial-mediated pathway could couple or 
      competitive with Mn(II) oxidation during Mn(II) removal is scarcely reported. In 
      this study, we reported a competitive Mn(II) removal occurred in nutrient-rich 
      condition during the indirect Mn(II) oxidation of Lysinibacillus sp. MHQ-1, i.e., 
      microbially-induced carbonate precipitation (MICP). In the presence of 1 mM 
      Mn(II), 39.4% of free Mn(II) converted to MnCO(3)(s) quickly within 100 h, and 
      then 11.6% of initial Mn(II) slowly oxidized to MnO(x) within 442 h. The urease 
      activity assay and the genome sequencing confirmed the existence of urease and 
      the absence of Mn(II)-oxidizing enzymes in the genome of strain MHQ-1. The urease 
      catalyzed the formation of carbonate ion that reacts with Mn(II) and the formed 
      ammonia raises the pH to initiate indirect Mn(II) oxidation. Genome survey 
      suggests the urease widely exists in various Mn(II)-oxidizing bacteria (MnOB), 
      emphasizing the importance to reconsider the composition, stability and 
      environmental effects of biological Mn(II) removal products in nutrient-rich 
      environment.
