DOI: 10.1007/s11368-019-02529-7
Abstract: Anaeromyxobacter is a typical representative genus of dissimilatory metal-reducing microbes. However, the community structure and metabolic function of Anaeromyxobacter have rarely been reported because of the limited number of Anaeromyxobacter isolations. Therefore, this study aimed… read more here.
