Strain M14 was isolated from manganese polluted soil and identified as Lysinibacillus sp.This strain was able to oxidize Mn(Ⅱ) to biogenic Mn oxide pellets (majored in the form of Mn (Ⅳ)).The adsorption and desorption analysis of gold ion Au(Ⅲ) were conducted using the biogenic Mn oxides.Results showed that the biogenic Mn oxides could successfully remove and recover the precious gold ion.This strain has been stored in China Center for Type Culture Collection (CCTCC NO：M2012084).The results of current study will be valuable for the recycling of gold and bioremediation of gold-polluted wastes.
