In the original article, the reference for Balch et al. (1979) was incorrectly written as Balch, W. E., and Wolfe, R. S. (1976). New approach to the cultivation of methanogenic bacteria: 2-mercaptoethanesulfonic acid (HS-CoM)-dependent growth of Methanobacterium ruminantium in a pressureized atmosphere. Appl. Environ. Microbiol. 32, 781–791. It should be Balch, W. E., Fox, G. E., Magrum, L. J., Woese, C. R., and Wolfe, R. S. (1979). Methanogens: reevaluation of a unique biological group. Microbiol. Rev. 43, 260–296.
The 2 L steel anaerobic canister used in our study was a modified version of a pressure cylinder described in Figure 5 of the above-mentioned publication (Balch et al., 1979). The length or the height of the modified unit was 17.5 cm.
