中国人. 研究了1株从锰污染的土壤中分离的细菌M14,初步鉴定其为赖氨酸芽孢杆菌（Lysinibacillus sp.）。该菌在生长过程中可以将Mn（Ⅱ）氧化成不溶于水的以Mn（Ⅳ）为主的生物锰氧化物。再利用这种生物锰氧化物去吸附和解析溶液中的金离子,从而达到了贵重金属回收再利用的目的。该菌保藏于中国典型培养物保藏中心,其保藏号为CCTCC NO：M2012084。本研究结果在净化和回收采矿等废水方面具有良好的应用前景。

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.
