All strains are derivatives of M. acetivorans WWM1 and were constructed by markerless exchange as described in Materials and Methods. Plasmids used for introduction of the ΔmtaA1, ΔmtaA2, and ΔmtbA alleles were pMP68, pMP70, and pMP65, respectively. The construction of WWM15 has been previously published (32) and was used to construct WWM28, WWM147, and WWM346.
