title: [Reduction of selenite to elemental red selenium under aerobic condition by Pseudomonas alcaliphila MBR].
abstract: OBJECTIVE
  We studied the reduction of soluble and highly toxic selenite to elemental red selenium, under aerobic condition by Pseudomonas alcaliphila MBR, with organic carbon as electron donor.
  
  
  RESULTS
  The strain could grow under pH 6-11 and resist to high concentration of selenite with the minimal inhibitory concentration of 50 mmol/L. After 5 days, the strain used sodium citrate as electron donor, and reduced 2.0 mmol/L selenite to elemental red selenium from the culture fluid, the elemental red selenium was stored outside the cells. The glutathione and nitrate could increase the number of reduction rate.
  
  
  CONCLUSIONS
  This study implies the application of Pseudomonas alcaliphila MBR to convert selenite to elemental red selenium.
