  1. a. for the β-galactosidase activity assay the bacteria were grown in the ED minimal medium with either sulfate or methionine as sulfur source. b. exp = exponential growth phase, stat= stationary growth phase. c. BFS1851 = mtnU::lacZ, BSHP7020 = mtnV::lacZ, BSHP7014 = mtnW::lacZ, BFS1852 = mtnX::lacZ, BSHP7016 = mtnY::lacZ, BFS1853 = mtnZ::lacZ.
