Species Allocrenothrix methanicaTs [Me.tha.ni.ca.] N.L. neut. n. methanum, methane; L. fem. adj. suff. -ica, pertaining to; N.L. fem. adj. methanica, pertaining to methane
Microaerobic. Cells are rods 1.0-1.5 μm wide and 1.9-5.0 μm long and form multicellular filaments. Filaments are linear, rarely branched. Cells are connected by conjugation-like structures. No production of gonidia has been observed. The reference strain AF98 was isolated from iron-rich microbial mat material from wetlands regions of Oze National Park (Japan).
