Abstract
An object of the present invention is to provide a method for efficiently recovering solid selenium or gaseous selenium from wastewater/waste using a microorganism. The present invention provides a method for recovering selenium, comprising reducing a water-soluble selenium compound so as to produce elemental selenium or gaseous selenium by allowing a sample containing a water-soluble selenium compound to come into contact at a temperature which is more than 35° C. and is 40° C. or less at pH 7.0 to 9.4 with a microorganism capable of producing elemental selenium or gaseous selenium through reduction of a water-soluble selenium compound.
