Abstract

ABSTRACT Leptospirillum ferriphilum strain UBK03 isolated from a mine in Jiangxi, China, is resistant to Ni 2+ (30 to 40 mM). A four-gene nickel resistance cluster was identified and, when transformed into Escherichia coli , enabled growth in 6 mM nickel. Mutation experiments revealed that the genes ncrA , ncrB , and ncrC could confer nickel resistance in Escherichia coli , whereas the gene ncrY could have a negative effect on nickel resistance.
