Methanogenic Bacteria, Including an Acid-Tolerant Strain, from Peatlands

ABSTRACT

Five pure cultures of methanogenic bacteria were isolated from Minnesota peatlands by enrichment culture techniques. One strain, identified as a member of the family Methanobacteriaceae by antigenic fingerprinting, was acid tolerant and able to produce methane at pH 3.1. Growth could not be demonstrated at pH less than 5.3.
